Background

How to Implement the Pay as you throw system

The amount of daily waste<1> emitted from 10.3 million citizens, 4 million households and 780 thousand businesses in 2012 was 9,189 tons per day, 0.88kg per person. All daily wastes should be discarded according to the regulations of the 25 autonomous districts. To discard the general waste (to be sent to incineration facilities or landfills), you should buy and use the standard waste bags sold by the relevant autonomous districts.

To discharge food waste, you should buy and use the standard waste bags or use the chip or RFID based system. In the case of large sized waste, you have to buy stickers from the relevant autonomous districts and attached them to the waste before discarding them, or you can hand such wastes over to specialized waste collection agents. (Ministry of Environment, Nov. 2012; Resource Recirculation Bureau, Ministry of Environment, Nov. 2012) The items that can be recycled to create resources or have value of resources like paper, scrap metal, large home appliances, small home appliances, fluorescent lamps, batteries, cooking oil, etc. should be separated and discarded according to the methods regulated by the government. (Minister of Environment, 2011)

In the case of the general waste and food waste, the discarders bear the whole or a part of expenses for waste collection and treatment and the cost depends on the amount of the discarded waste. That is why the waste fee in Seoul is called pay as you throw system. The measuring method for general waste and food waste is different. The measuring method for general waste is the standard bags which are made according to the quality standards<2> set by the government. The waste discarders can buy the bags in desired sizes at designated stores (such as convenience stores, laundries, etc.).

The expenses for waste collection, treatment and production of bags and the commission for the stores are included in the price of the bags, granting the nature of marketable securities to the bags.

The measuring method for food waste are either an RFID based waste weighing system, chips (or stickers) or standard waste bags, more various than the method for general waste. RFID based waste weighting system is used to measure the weight of waste and impose consequential fees. An advantageous trait of this system is accurate weighing of the discarded waste. But the devices have disadvantages at the same time, because the system has a complicated configuration consisting of weighing devices, discarder recognition system and storing devices to save the discarders and results of weight measurement. Chips or stickers are used with the standard containers. Daily volume measuring and monthly volume measuring are all available with this solution.

Except for recycling products, large sized waste and used coal briquettes that are allowed to be discarded using other routes, all wastes discarded in Seoul must be made according to the volume-rate disposal system without exception and the corresponding fees must be paid. If you do not pay the fees when you discard your waste, it is a violation of the waste management law or ordinances of the local government, and is subject to the penalties of those laws or ordinances.

Background of Introduction of Pay as you throw system

In the late 1980s and early 1990s, the whole society of Korea was filled with high public esteem and vitality due to the successful hosting of Asian Games in 1986, Seoul Olympic Games in 1988 and continuous economic development. There were lots of products on the market and plastic products were produced in mass volume thanks to the development of production technologies.

Lots of products led to increased amounts of waste. Meanwhile, Seoul, the capital city of Korea, could not secure the space for landfills to treat wastes any more while the space of Seoul was being expanded to the outskirts of the city.

As the capacity of Nanji Landfill (operated from 1978 to 1993) was reaching its limit, the central government led a project to establish new waste treatment facilities in the metropolitan area to treat the waste from Seoul, Incheon and Gyeonggi-do (province) in 1989. But it was very difficult to move forward because of the strong opposition from the residents living the areas near the expected sites for facilities.

The Seoul Metropolitan Government also planned to build 11 incineration facilities to treat all daily waste from Seoul, but encountered opposition from neighboring citizens and strong voices of the civil societies concerned about excessive facility construction. In 1996, Seoul managed to complete the construction of incineration facilities in Yangcheon (400 tons per day) and Nowon (800 tons per day), and just 4 more facilities (2,850 tons per day) could be built after that. In order to address the issues of waste which had increased in quantity and had deteriorated in quality, the government started to have interest in waste recycling as an alternative mean.

Recycling boxes had appeared in the apartment complexes of Seoul in 1990, and began to be provided to detached house areas the next year. However, the citizens were not familiar with the separate discarding for recyclables. In the case of the detached house areas, half of the collected recyclables was general garbage. On the other hand, the changes in the waste management system costed a lot of money, using landfills a long distance away, constructing incineration facilities, separating the waste into general garbage and recyclables to be collected in different ways, etc. As shown in the data from 1991, the financial expense spent in the waste management was KRW 280 billion and the fee revenue was only KRW 25.4 billion, covering just 9% of the total costs. Most of the expenses for waste treatment were taken by the general account budget, and the part paid by the citizens, the waste generators, was very small. (The Seoul Metropolitan Government, 1992)

<Figure 1> Main Waste Management Projects before and after the Introduction of Pay as you throw system

In this situation, the government started seeking methods to reduce the amount of waste fundamentally (waste reduction), to lower the dependence on the incineration facilities or landfills by establishing the separate discarding of recyclables (promotion of recycling), and to charge the citizens who generate waste for the involved costs of the waste management (securing financial resources for waste management), and selected the pay as you throw system as an alternative. Entering the 1980s, the necessity of introducing the pay as you throw system had been raised in a corner of academic circles (Environmental Planning Institute, Graduate School of Environment of the Seoul National University, 1983; Jeong-jeon Lee, 1991).

However, the fees for waste disposal in Seoul had been collected in a kind of tax form based on the building areas or property taxes which had nothing to do with the amount of waste produced before the pay as you throw system was introduced in 1995 (Ki-young Yu and Jae-cheon Jeong, 1995). The pay as you throw system taken as the waste disposal fee system through establishment of social atmosphere, creation of implementation conditions, pilot projects, etc. has gone through changes and development until it reached its current form.

History

- Preparation Stage (1992~1994)

The pay as you throw system was introduced in 1995, however the preparation started in the early 1990s and the practical arrangement began in 1992 with the government at its center. First, the survey and research to verify the validity of the introduction of pay as you throw system had been conducted by Korea Society of Waste Management from September 1992 to January 1993. The main contents of the survey and research were relevant amendment of legislations, enforcement measures, expected effects, ripple effects, etc. In 1993, the government began the process of opinion collection from all walks of life regarding the introduction of pay as you throw system.

Public hearings and meetings with private organizations consisting of relevant experts, cleaning companies, etc. (Feb. ~ Jul. 1993), meetings with the consumer groups, groups of housewives and waste bag manufactures (Jul. 1993), meetings with the managers of the urban and provincial cleaning departments and opinion collection of the waste subcommittees (Jul. ~ Aug. 1993) were held during the process. Inquiry about the opinions of related organizations and institutes on the legal status of standard waste bags was also conducted (Sep. 1993). The result was that the waste bags could be regarded as official documents as long as the positions of mayor or district heads as well as the marks of the city hall or the autonomous district offices were on the bags, and that it would be considered forgery of official documents if anyone forges and sell the bags.

One year before the pay as you throw system was introduced in country-wide, pilot projects were conducted in 33 cities, counties and districts (Apr. ~ Dec. 1994). In Seoul, Jung-gu as a commercial area, Seongbuk-gu as a detached housing area and Songpa-gu as an apartment area participated in the pilot projects (The Seoul Metropolitan Government, 1994). Before that, the central government announced the implementation measures of the pay as you throw system, including the amounts of the waste fees, how to distribute the standard bags, how to treat the expected increase of recyclables, etc. (Nov. 1993).

During the pilot projects, the government concentrated on finding the waste discarding status, standard waste bags, degree of citizens’ participation, flow of the community opinions, etc. The government assembled a civil assessment team consisting of 7 civic groups including YWCA, YMCA, Green Korea United, the Korean Federation of Environmental Movement, etc. and 165 monitoring agents to provide the ability to assess and report the status of the projects. There were big concerns about negative factors, such as illegal waste dumping, however the positive assessment was dominant due to the 40% reduction of waste amount, 100% increase of recyclables collection, reduced cleaning cost, social expansion of awareness about waste reduction, inspiration of self-confidence of the officials, etc.

Based on the problems that appeared during the implementation of pilot projects, the government made “Guidelines of Pay as you throw system” (Sep. 8^th, 1994) to enforce the system on a national scale. On November 7^th, 1994, the government held a meeting with the related urban and provincial officials to conduct an interim evaluation on the project implementation of the local governments. On December 7^th of the same year, the government issued guidelines of how to fix the problems that were discovered during the interim inspection such as the basic plans to handle the expected rapid increase of regional processing of recyclables, emergency transportation period setting against the emission of large amount of waste just before the enforcement of pay as you throw system at the end of the year, the reinforcement of manpower to facilitate the pay as you throw system, etc.

In addition, the government processed the revision and amendment of related ordinances, management of waste bag manufacturing, designation of the stores to sell the bags, public relation activities, etc. in preparation for the introduction of pay as you throw system on January 1^st, 1995. In particular, the government carried out a public relation campaign to ease the citizens’ complaints of “why we should pay for waste disposal?” via media outlets such as TV commercial programs, advertisements in the daily press, TV talk shows, etc. and made and distributed promotion materials like VTR tapes, PR books, posters, etc. (Ministry of Environment and Korea Environment Institute, 2012)

- Introduction Stage (1995)

The pay as you throw system was implemented nationwide as of January 1^st, 1995. As a result of the implementation of the system, the previous waste collection fee was replaced with the value of waste bags and the bags could be used in the region that was printed on the bag. General waste was to be placed in bags purchased from the designated stores up to the dotted line and discarded in the front of houses. The recyclables were separated into paper, bottles, cans and plastics and then discarded. The large waste like refrigerators and cabinets were collected after prior notification by phone call to the administrative organizations containing address, name, kind and size of the waste, the confirmation of the visiting officials and the issuance of the bill for disposal fees. In consideration of low-income people, the coal briquette ashes were allowed to be discharged without using the standard bags. For the protected groups under the livelihood protection law and other poor people authorized by the heads of local governments, around 60ℓ of standard bags were provided for free or the purchasing price was reduced (Ministry of Environment, May 1997).

In the beginning stage of the system, the citizens seemed to not adapt to the implementation of the volume-rate waste disposal methods. There were many cases where the citizens could not distinguish recyclables from general household waste. Out of selfishness, citizens dumped household trash prior to the enforcement of pay as you throw system. They especially discarded large waste like cabinets, refrigerators, etc. at the same time to intensify the confusion. However, these things happened often only in the early stages, and became stabilized as time went by.

In April 1995, the government had an evaluation meeting 100 days after the implementation of pay as you throw system. During the period, a survey of 1,000 households was conducted and the results showed that the citizens appeared to almost fully adapt to the system in a month after the implementation. 98.6% of the respondents had evaluated that they practiced the system well, and the capacity of the most widely used standard bags was 10ℓ, 5ℓ and 20ℓ in order.

The improvement and complement points proposed in the evaluation meeting were strength and convenience of the standard waste bags, application of the system to the wastes in public places, enhancement of convenience for separate collection of recyclables by showing the recycling mark, timely collection of recyclables, prohibition of collection of recyclables that were mixed with the waste, prohibition of excessive packaging of disposable products and preparation of its basis, initiative practice of the system in government organizations, preparation of the criteria for penalty enforcement, establishment and expansion of recycling networks, securing the appropriate price of standard bags, linkage of allotment/deposit for the pay as you throw system, supply and promotion of system related information, etc.

- Development Stage (After 1996)

Many things that concerned the government and caused inconvenience to the citizens regarding the implementation of pay as you throw system. However, the system was recognized to have lots of positive effects, including the practical reduction of the amount of waste, facilitation of separate disposal of recyclables and expansion of social awareness on waste reduction from when it began in 1995 through its 20-year anniversary in 2015. In the meantime, the pay as you throw system has been developed and changed continuously.

First, the most troublesome problem in the beginning stage was how to handle the collected recyclables. It was resolved by enacting the producer responsibility regulation in 2003. The recyclables are divided into paper, plastic containers, scrap metal (including cans) and glass bottles. Under the pay as you throw system, the amount of collected recyclables increased but the demand for recyclables was the same. The producer responsibility regulation had been executed using the deposit system for a limited number of items including paper packs, PET bottles, iron cans, glass bottles, etc. However, the system did not work well enough to be of help to increase the demand for manufacturing, because many manufacturers gave up the deposit.

Thus, the government decided to convert the deposit system to an expanded producer responsibility scheme, which required the producers to treat the recyclables. Additionally, the relevant items were greatly expanded to include paper packs, plastic containers, scrap metal (including cans), glass bottles, large sized home appliances, small sized home appliances, fluorescent lamps and batteries. As a result, the supply and demand of recyclables were dramatically improved.

In 1997, the government started to make and provide waste bags exclusively for waste that was difficult for both discarders and collectors to handle. The special waste bags were used to hold broken glasses, small amounts of construction waste, etc. that are sharp and heavy enough to cause physical damage, especially in the process of collection. The special bags were made of tough and easy-to-handle materials (poly propylene) different from those used for the general waste bags.

The standard waste bag, as the core method for implementing the pay as you throw system, was a very convenient tool for measuring the amount of waste in a large city like Seoul, Korea where it is difficult to identify the discarders. But many people pointed out repeatedly that the waste bags were disposable products and became waste after a single use. In order to address the problem, the government recommended selling standard bags for goods transport at large supermarkets (E-mart, Homeplus, Lotte mart, National Agricultural Cooperative Federation or Nonghyup Hanaro Club and Mega Mart). The large supermarkets located in Seoul began to sell the standard bags in 2010. The bag was called the reusable bag, consumers could use it as a standard waste bag, and the price of the reusable bag was same as the standard bag selling at other stores.

The most innovative development was the introduction of the weight-rate waste disposal system to weigh food waste. Many autonomous districts could not apply the principle of pay per disposal system properly in the case of food waste. Most of the districts used the standard boxes for the food waste, and imposed the same fees to all households regardless of the amount of waste. Some districts collected food waste free of charge. There were reasons for their methods. The material of standard bag was polyethylene, which would become foreign material in the process of food waste treatment, lowered the quality of feed or compost made from the food waste, and made the feed or compost consumers reluctant to buy. The districts were confused because they were not sure of the validity of imposing fees for the collection of food waste that could be treated only using the garbage recycling methods, while they were collecting the recyclables free of charge.

However, too much food waste was generated, and it was difficult to turn the food waste into recycled resources and to apply the expanded producer responsibility scheme while taking care of the food waste. Thus, the government decided to introduce the weight-rate waste disposal system in order to reduce the amount of food waste. The Seoul Metropolitan Government also enacted the system in 2003 (The Seoul Metropolitan Government, https://seoulsolution.kr).

The government recommended that the system should operate not on the basis of volume, but on the basis of weight when treating food waste because food waste is heavier than general waste. As a result of this change, it was reported that food waste was reduced by 10~30% (Korea Institute of Industrial Relations and Korea Environment Corporation, Dec. 2013). By using this system, the amount of food waste is recorded by each individual when the food waste is discarded. Based on the recorded information of each individual, the monthly fees are imposed. However, this system is currently only operated in a portion of apartment complexes, because the installation and operation of the weighing system costs a lot and requires space for the installation. For detached houses and restaurants, the standard bags or standard tanks with chip attached are generally used. (Resource Recirculation Bureau of the Ministry of Environment, Nov. 2012)

As described above, the meter-rate based waste fee system has been steadily developed. During the process, the government made big efforts to develop the system by implementing periodic status and problem monitoring. It found and evaluated the degree of system settlement, inconvenient factors when discarding the waste, items to improve in the system, things to improve in the related cleaning system and things to improve in the recycling market. In the beginning stage, the government evaluated the achievement of the system every year and held an evaluation meeting in 2005 to look back the achievement of the system over the first 10 years. In 2004, it started to investigate the results of standard bag sales by the local government, waste treatment facilities, how to secure the financial resources for cleaning, response performance against illegal waste dumping, etc. and to issue the results of the investigation as a government report. The guidelines for the waste disposal system established in the early stage have been amended many times in 1997, 2001, 2003, 2006, 2008, 2009, 2010 and 2012.

Achievements

Acceleration of Waste Reduction

According to the statistics of Seoul, in 1995 when the pay as you throw system was implemented, the amount of waste was reduced by 8% compared with the previous year and 11% in 1996 compared with two years before. In the beginning stage of the system, large waste was discarded in large quantities because it was free at that time. Therefore, the amount of waste discharged in the 2^nd year, 1996, can be assumed to be more accurate. So the actual percent of waste reduction was about 11%, which equaled an amount of about 1,712 tons per day. The average capacity of the 4 incineration facilities in Seoul is 700 tons per day<1>. In other words, the amount of waste reduced was equal to the capacity of 2~3 incineration facilities.

Of course, there were different arguments for the reduced wastes. According to an opinion, other factors besides the pay as you throw system such as the rapidly reduced use of coal briquettes and the regulatory policy on disposable items and product packaging affected waste reduction (Yong-seon Oh, 2006). On the contrary, another study showed that even when the other factors are considered, it was the waste disposal system that clearly brought about the reduction in waste (Kwang-ho Jeong et al, 2007). The controversial evaluations above were not on the waste reduction itself, but on the size of the system’s effect. The citizens became more sensitive to exaggerated packaging when choosing products, took only the products, leaving the packing materials, and requested to return the packing materials of delivered products. These reactions of the consumers influenced manufactures and were reflected in product design. After the introduction of pay as you throw system, it was obvious that there were changes in the consumption pattern and those changes were admitted by all.

<Table 4> Change of Waste Amount before and after the Enforcement of Pay as you throw system

Classification	1994 (Preparation)	1995 (Enforcement)	1996 (2nd Year)
Generation Amount (tons/day)	15,397	14,102	13,685
Generation Amount (kg/day)	1.43	1.33	1.31

Facilitated Separation of Recyclables and Early Adaptation of Waste Separation

The outstanding results of the pay as you throw system included the facilitated separation of recyclables and early adaptation of waste separation habit in a short period of time. The amount of recyclables increased by 881 tons per day in 1996 compared to 1994. The proportion of recycled waste of the total amount of processed waste was 20.5% in 1994, 29.3% in 1995 (enforcement of the system) and 29.5% in 1996, showing a rapid increase of 9% in 1996 (2^nd year) compared with that in 1994. There were different evaluations of the waste reduction effects, but everyone agreed on the adaptation of separate disposal of recyclables. The facilitated separation of recyclables led to the reduced demand for the waste treatment facilities. Because the average capacity of the incineration facilities in Seoul was 700 tons per day, the separation of recyclables contributed to the reduction of 1.3 incineration facilities worth of waste.

Recycled Amount (tons/day)	2,940	3,156	4,131	4,037
Recycling Rate (%)	18.4	20.5	29.3	29.5

Securing the Waste Management Expenses with Fees

The financial independence rate (appropriation scale by the income from fees, etc. compared to the expenses for waste management) in 1991 was just 9%, meaning that the expense burden of the waste discarders was very low (The Seoul Metropolitan Government, 1992). It is for this reason that the pay as you throw system was introduced. With the pay as you throw system, the fees paid by the waste discarders increased from KRW 119.9 billion in 1993 to KRW 153.6 billion in 1995 (growth rate: 28%), and there was a more desirable aspect. The total income from the fees got bigger without increasing the burden per household while maintaining fairness in charging the burden of fees. In other words, the monthly fee per household before the introduction of the pay as you throw system was KRW 2,102, and KRW 2,288 after the system introduction, showing little difference except that the waste discarding sources who were paying the waste fees were expanded from 1,690 thousand households to 2,970 thousand households. In conclusion, the introduction of pay as you throw system was effective in improving the unreasonable fee structure and increasing the fee income.

Fee Income (KRW Mil.)	119,912	153,638	1.28

Creation of Economic Benefit

In 2005, the government evaluated the 10-year performance of pay as you throw system that was introduced in 1995. According to the evaluation, 1 ton of waste reduction created a benefit of KRW 144,071 and 1 ton of waste recycling created a benefit of KRW 18,901. The benefits of waste reduction came from the reduced cost for waste collection and transportation, installation of treatment facilities and operation of such facilities. The benefits of recycled waste were the values earned after deducting the cost for collection and transportation, sorting, processing, etc. from the total value of the recyclable items (Korea Institute of Industrial Relations and Korea Environment Corporation, Dec. 2013). In the case of Seoul, it seemed that the cost for waste collection, transportation and processing was reduced by KRW 90 billion and the recycling created KRW 6.1 billion of economic benefits, KRW 96.1 billion in total per year if the government evaluations above were applied to the performance of pay as you throw system in Seoul.

Meaningful Experiences

- Thorough Preparations

The volume-rate waste fee collection system is inconvenient to citizens as the waste discarders. Even the experts opposed the introduction of the system, saying that foreign countries hesitated its introduction out of concern for possible illegal waste dumping. In Korea, the introduction of pay as you throw system was made with the support of the government, cities and some scholars fearing the difficulties in securing the waste treatment facilities, not with the support of the majority of people.

To cope with this negative atmosphere, it was necessary to remove the institutional obstacles in advance, to create an amicable social atmosphere for the system, to find the effects and the problems through implementing pilot projects and to persuade the people of the benefits. In particular, it was imperative to find the system implementation methods suitable to each city in during preparation stage. In the case of Seoul, it was not easy to identify the waste discarders because there were many high-rise buildings such as apartments and shopping centers and the city space was small and narrow. That was the reason why Seoul took the standard waste bag as the method to measure the amount of waste.

However, it was desirable to use baskets only for the waste in regions with many detached houses and developed roads because it was possible to prevent the waste of disposable standard bags and illegal dumping by making an agreement with all dischargers on the size of waste baskets and to reduce the waste collection cost by introducing the automated basket loading vehicle system.

Cooperation with the Civil Society

The civil society in the environmental field played a large role in adapting the pay as you throw system in Korea. When the system introduction was in the middle of discussion, the civil society did not have a favorable opinion of the system. It expressed concerns about illegal waste dumping to avoid paying the waste fees and signs of uneasiness about the intention of government to shift the responsibilities for waste reduction and waste recycling to the people. However, the society started to see the positive sides of the system after participating in the site monitoring activities and ensuring the citizens’ active participation during the periods of pilot project and the 1^st year of project implementation.

The civil society has taken part in the evaluations for the pilot project and the first, second and tenth years of the system implementation persistently. Even now it is involved in the process of assessment for the implementation of the food waste disposal system. The positive evaluation from the civil society has contributed greatly to the change of the attitude of the mass media and the national consciousness.

Securing the Disposal Paths for the Increased Amount of Recyclables

The separate discarding of recyclables free of charge was implemented in a short time. How to process the collected recyclables became the task of the government. The biggest headache was how to handle plastic containers (PE, PP, PS and PVC materials) other than PET containers. While they were designated as recyclables, there were not enough infrastructures equipped to treat plastic products. In addition, the producers were not responsible for the treatment of waste plastics because the waste charges were imposed on most of the plastic containers.

The issue was solved in 2003 when theE government gave financial support to help the plastic recycling operators install and operate the relevant facilities, made the public sectors purchase recycled plastic products preferentially, and to impose the obligation to collect and process recyclables which had weak treatment basis in the market (including the plastic containers) to the manufacturers (Extended Producer Responsibilities Scheme).

With the introduction of pay as you throw system, an unplanned recycling item was added. Because of the serious bad smell from the landfills, lots of complaints were raised one year after the system’s introduction. The same complaints were made about the roads to the waste treatment facilities. The cause of the problems was food waste. The large amounts of papers acted as buffers in standard bags, absorbing the leachate and blocking the smell of the food waste to some degree, but the papers were classified as one of the recyclable items.

The main cause of the bad smell was the fact that papers were no longer discarded with general waste. The problem was resolved by collecting the food waste separately and changing the treatment system on a large scale. Landfill of all food waste was prohibited from 2005. The government started the construction of food waste treatment facilities in 1998. Seoul has 5 public facilities to treat food waste in five places now. The remaining food waste is processed using private facilities.

Prevention of Illegal Acts

When reviewing the system introduction, the most concerning side effect was illegal waste dumping to avoid paying fees. Actually, many people dumped household or business side trashes in public street wastebaskets or in secluded spots or desolate places and discarded the waste without using standard waste bags. In order to prevent illegal waste dumping, reflectors were installed and places used for illegal dumping were changed into flower gardens. Some districts removed the wastebaskets on downtown streets.

The illegal dumping was reduced a lot, but not eliminated though. In the meantime, the systems to impose penalties for committing illegal acts and to supply standard bags to the low-income class free of charge were prepared.

- Revision of Legislation

The enforcement basis of pay as you throw system is the waste management act. The detailed implementation methods are authorized to the local governments by their ordinances. The waste management act also deals with the penalties for illegal dumping to avoid the fees.

Each district covers the specific regulations on how to enforce the system in its own ordinance. It regulates the kinds of waste under the application of the pay as you throw system, discharging methods, fees, kinds/colors/materials of the standard bags, supervision of standard bag manufacturing and safe management, designation of the stores to sell standard bags, guidelines for standard bag sellers, criteria on the cancellation appointment of standard bag sellers, etc.

The size, material, strength and kind are determined based on the Korean Standard on Plastic Products. All specifications of standard bags are subject to the standard and standard bags made against the standard cannot pass the inspection. To prevent the counterfeiting of bags, the seals for printing on the surface of standard bags were kept by the autonomous districts and handed over to the manufacturers only when they produced standard bags. In the case that a person makes and distributes counterfeit bags, the person would be punished according to the regulation on the fabrication of official documents under criminal law.

Background Information

After 1980s Korea enjoyed unprecedented economic revitalization and abundance of industrial products based on economic development that started in earnest since 1960s and overall change in industrial structure. The amount of waste generated in the city skyrocketed due to mass production and consumption of affordable plastic products and synthetic packing material due to the development in domestic production technology.

In the meanwhile, due to the shift in the tendency of huge population, who used to flock to Seoul for living and work, started moving out to the suburb area, Seoul’s neighbouring cities were turning into new towns accommodating Seoul’s excess population. As a result, it got more difficult to secure landfill sites in the suburb and even impossible to do so in Seoul, which had been major waste treatment facility. Gyeonggy Province and City of Incheon were not exception in having difficulties in securing landfill sites. Government took the lead in promoting the establishment of the landfill sites (Sudokwon Landfill Site) where Seoul, Gyeonggi province and Incheon could share. However, it was not smooth at all to establish the Sudokwon Landfill Site as the sense of repulsion towards non-preferred facilities like landfills was already widespread.

While going through difficulties in securing landfill sites, Seoul established a waste treatment plan with the focus on reducing dependence on landfills in 1991. The plan mainly covered constructing 11 incineration facilities. However, even that plan was severely opposed by residents of designated facility area. Civic groups pointed out problems in the plan arguing the size and the number of planned incinerator facilities construction was excessive. So far, as a result, 4 incinerator facilities have been built in Seoul.

As an alternative to reducing waste volume to be buried, recycling policy had been promoted. In 1990, the recycling bin started to be installed in apartment complexes. Due to a level of success so the bins were installed in detached houses area as well. However, residents were not accustomed to separating recyclables from garbages so it was not unusual to find the trash from the recycling bins.

It required a huge amount of costs to construct incinerator facilities and promote recycling in order to overcome the situation where landfill sites got farther away from the downtown. In 1991, Seoul and autonomous gu (administrative district, borough) spent a whopping 280 billion KRW in waste management while residents spent only 25.4 billion KRW. Residents, who discharged the garbage, shared only 9 percent of the costs in waste management.

Due to such situations in 1980s and 1990s, government was desperate in finding ways to invite active public participation in recycling and charge the public more for the growing costs of waste treatment.

Volume-based waste charge system is a sort of solution based on ‘The Polluters Pay Principle.’ The theory supporting the need for the volume based waste charge system had already been raised in 1980s. However, before the volume based system was in place, waste treatment fees were levied based on the gross area of the building or on the property tax. Back then, waste treatment fees were collected as a type of tax. Table 1 below summarizes the changes of the waste charge systems up until the implementation of volume based waste charge system in 1995.

The Importance of the Policy

The type of waste subject to the VBWF system is municipal solid waste (MSW) generated from households, commercial sectors and small businesses. Designated waste and industrial wastes defined by Waste Management Act are not subject to VBWF system. VBWF system is based on the ‘pay-as-you-throw-principle’, which charges according to the amount of discharged waste by selling mandatory standard garbage bags. People should use pre-paid garbage bag in order to discharge waste.

VBWF system has been designed to charge in proportion to the amount of discharged waste and to the costs required in the waste treatment. People are induced to reduce the waste amount on voluntary basis. Wastes discharged as reclyable goods are exempted from collection fees, thus inducing recycling from separate waste collection, which is good both for the residents and authorities. Reduced amount of discharged waste means reduced fees for the residents and also means less dependency on the incinerating facilities and landfill facilities. VBWF system is meaningful as a policy as it changes residents’ patterns of waste disposal.

The efforts to change citizens’ pattern of waste disposal by awareness campaign or education may be more convenient but may not gain desired results or may gain, yet, very slowly. As a way to control behaviors against environmental protection, government rules and regulations have long been resorted to but enforcement requires human resources, giving rise to high cost for the policy implementation or due to insufficient number of personnel, enforcement had not been conducted. Regulation-oriented approach may not encourage consumers to make voluntary efforts to reduce pollution lower than permissible level. On the contrary, when residents are encouraged to change their behavioral patterns by gaining economic incentives (via VBWF system) proportional to the amount of the reduced amount of discharged waste, residents are motivated to reduce the waste more. After all, VBWF is a very environmentally desirable and effective way to bring about changes in behavioral patterns of residents.

Relevance with Other Policies

Today’s waste management policy aims to reduce the waste volume based on the reduced waste generation at source and reuse of recyclable wastes. The waste management policy also plans to recover material or energy from the waste and turn them into resources. Lastly, the wastes, which had not been processed from the previous two steps, are requested to be processed safely by being incinerated and buried.

Therefore, it is very important to make a reasonable estimation and strike a balance between the amounts of waste to be generated, waste to be recovered as resources, and waste to be processed by burning or burying. Particularly, VBWF system has direct impact on other relevant waste management policies including policies on waste management facilities as VBWF system makes a huge contribution to suppressing waste in the first phase, waste generation, of the waste management policy.

Until 1980s, private sector took the lead in the recycling market whose focus had been collecting discarded papers, scrap metals and glass bottles. Recyclable wastes were collected by junk men. To the low income people, scavenging for recyclable items had been a crucial means of livelihood at the Nanjido landfill. Recycling bin installed by civic groups and Korea Resources Recovery and Reutilization Corporation (KORECO) started to appear by the time when it was hard to secure landfill site and incineration facilities had become controversial in 1990.

The recycling bin started to spread across detached house area since 1992. As social conflicts got intensified over incineration facilities and waste landfill, high expectation were pinned on turning the wastes into recyclable items as alternatives to incineration and reclamation. Obviously, the separate disposal and collection of wastes and recyclables had not been settled as it was not unusual to find wastes mixed in the recycling bins or recyclables items in the waste bags. The VBWF system implemented since 1995 had solved such problems. The VBWF system implemented in Korea has been remarkably effective in settling the separate collection and disposal of voluminous papers, plastic containers and cans, which requires purchasing standard waste bags to throw away their garbage, thus waste collection fee is charged in proportion to the amount thrown away.

The government revised the Waste Management Act in 1998 saying starting in 2005 so the direct land-filling of food waste generated in urban areas would be completely banned. With the implementation of the VBWF system, residents living around waste treatment facilities including incineration and landfill site expressed opposition to the facilities, as food waste was discharged using the VBWF bags, which gave rise to the various environmental problems including creating serious foul order and harmful insects.

Meanwhile, autonomies, responsible for the MSW, faced more difficulties when supply of recyclables increased. It was not unusual to see recyclable items piled up in the regional authorities’ recycling depository as there was no available market for the recycled goods. Also, due to free-fall of trade prices, private sector refused to purchase the recyclable items. Selecting and securing food waste treatment facilities were also serious headaches as residents around the would-be facility sites were deadly opposed to them and the other option of using private facilities were simply too expensive.

In the end, VBWF system had met the policy goals of waste reduction and separate disposal and collection of recyclable wastes but it generated the demand for policies such as securing markets for supply and demand of recyclable markets and establishing food waste management facilities, which led to the introduction of Expanded Producer Responsibility (EPR) in 2003 and ban on the direct land-filling of food waste in 2005.

Policy Objectives

Reduced waste generation at source
Settlement of separate disposal and collection of recyclable items.
Reduced dependence on the waste processing facilities (incinerating facilities and landfill facilities)

Main Policy Contents

Volume-based Waste Fee system is a policy to charge fees in proportion to the amount thrown away. In Seoul, all wastes should be discharged in accordance with VBWF system, with the exception to the recyclable items, bulky waste and coal briquette whose discharge are otherwise specified, and fees are charged proportional to the amount discharged. Depending on the waste type, their volumes are measured differently. Wastes are divided into general wastes (or MSW) to be incinerated or buried, food waste, and recyclable waste which could be turned into resources.

General waste refers to waste to be incinerated or to be buried. Waste volume is measured through standard garbage bags, which were taken by the district, or gu, offices to be divided into household, commercial, and business use. Bags are in 2, 3, 5, 10, 20, 30, 50, 75, and 100 liter sizes, with people able to purchase the size and quantity of bags they wish at designated stores. General waste therefore is treated based on volume based charge system.

Food waste could be discharged in various ways. People may use standard waste bags sold by local authorities, standard plastic container equipped with electronic chip or sticker, and weight-based payment using electronic card with RFID. In the case of RFID based food waste treatment, discharger should swipe a card before gaining access to residential waste bins. The chip containing user’s name and address allows the authorities monitor the weight of individual’s waste. The system accumulates the fee on a monthly basis, and each household receives a monthly food waste disposal bill.

Other items such as papers, plastic packaging materials, glass bottles, scrap metals, discarded home appliances, discarded florescent lamps, used batteries and used cooking oil are classified as recyclables and should be discharged in the way prescribed by the Ministry of Environment.

Colors of VBWF bags	General use bags and reusable bags: White Public　use : blue	General Use : Yellow

However, ordinary VBWF bags are little better than disposable trash bags which could be used only once. The Korean Government, for its part, as an effort to solve, albeit partly, such issue, allowed shopping giants such as E-mart, Home plus, Lotte mart, Nonghyup Hanaro mart, Mega mart to offer the reusable VBWF bags and customers could use them as standard trash bags.

Since 2013, food waste has been subject to volume-based waste fee system in Seoul. The chip or sticker system requires a discharger to buy a payment chip or sticker and attach it to a standard collection container to be picked up. The container serves as a disposable volume measuring device or monthly volume measuring devices. The merit of RFID system is that it accurately scales waste volume and fees are charged according to the total volume. However, RFID system could be quite complicated as it has to be equipped with weight measuring device, discharger recognition system, and volume tracking & storage devices.

When disposing large items, discharger should buy sticker from the regional authorities and place it on the item before they are picked up, or let them be picked up by garbage haulers.

Discharge Fees

In accordance with the VBWF system, dischargers pay partial or all costs of collecting and treating them when they throw away municipal solid waste and food waste. The amount of fee is determined by the volume of generated wastes, which is why the system is named as volume-based waste fee system. The price of VBWF bags includes the costs of collection, treatment, manufacturing, and sales profit of the VBWF bags.

Policy Effects

1) Reduction of Household Solid Waste Generation

According to Seoul’s statistics, the volume of waste generated in Seoul had been reduced by 8 % in 1995 and 11% in 1996 compared with that in 1994, which was tantamount to reduction of 1,1712 ton/day. Since the VBWF system has been instituted, consumers have shown changed pattern of waste generation, improved awareness of waste disposal, which well explains the cause of the reduction in statistics. For example, consumers got sensitive to over-packaging of products, brought only product part, while leaving the package materials at the sales shop, requested the collection/return of packaging material when delivered, which, in turn, affected product design. Some quarters, of course, argued the waste reduction was hardly due to the VBWF system, but due to reduced consumption of coal briquette, changes of charging basis from volume to weight, dwindled production and consumption in the wake of economic crisis that hit Korea hard in 1998 and the Government’s separate implementation of relevant policy. However, reduced waste generation was a very natural consequence of the policy considering the principle of environmental policy, VBWF system. Therefore, the level of the policy effect could be controversial but it does not make sense to argue against the effect per se.

Table 3. Changes in the Waste Generation

Change	1994 (Preparation Period)	1995 (Implemented Year)	1996 (Institutionalization Period)
Generated Volume (ton/day)	15,397	14,102	13,685
Generated Volume (kg/day)	1.43	1.33	1.31

2) Contribution to the Settlement of Separated Disposal and Collection of Waste and Recyclable Goods

The most apparent outcome of the VBWF system is its contribution to the settlement of separated disposal and collection of waste and recyclable goods in a short space of time. In accordance with the VBWF system in Korea, discharged recyclable waste are collected by authority free of charge. Papers, plastic products and cans are sizable which means the more you discharge the recyclable items (instead of throwing them away in VBWF bags), the more you can save.

Recycling performance (the recycled amount) in 1996 had increased by 881 ton/day compared with that in 1994. Out of overall waste treatments, the recycled volume had shown significant rise from 20.5% in 1994, to 29.3% in 1995 (the year VBWF system was introduced), to 29.5% (2 years into the introduction of VBWF system). The separate disposal and collection of wastes and recyclables had led to reduced demand for waste treatment facilities.

Category	1993 (Flat Rate)	1994 (Preparation Period)	1995 (Implemented Year)	1996 (Institutionalization Period)
Waste Generation (ton/day)	16,021	15,397	14,102	13,685
Recyclables Generation (ton/day)	2,940	3,156	4,131	4,037
Recycling rate (%)	18.4	20.5	29.3	29.5

3) Securing Waste Treatment Costs from Profits of VBWF System

In 1991, Seoul’s financial independence of the cleaning budget was as low as 9%, which was calculated by dividing the total profits from the sales of waste bag and recyclable materials, fees for the disposal of bulky waste, and penalties by the annual waste disposal cost. In other words, dischargers’ share of responsibility in cleaning was very low (SMG, 1992). With the implementation of VBWF system, dischargers’ share of payment had risen by 28% from 119.9 billion KRW in 1993 to 153.6 billion KRW. While the overall fees from VBWF system had risen, the charge per household had not increased. That is due to improved equity of the system. For example, monthly payment per household had risen from 2,102 KRW to 2,288 KRW. Yet, the number of households paying the fees had risen from 1.69 million to 2.97 million. The implementation of the VBWF system had improved unreasonable charging system, which led to the rise in the revenue from the VBWF system.

Category	1993(Flat Rate)	1995 (Implemented Year)	1995/1993
VBWF Revenues (million won)	119,912	153,638	1.28

4) Creation of Economic Benefits

In 2005, Korean government assessed the outcome of the VBWF system to commemorate the 10th anniversary of the system which had been in place since 1995. The assessment said that one ton of waste reduction generated economic benefit of 144,071 KRW and one ton of recycled waste creates economic value of 18,901 KRW. The benefits generated from the waste reduction were due to the cost savings from waste collection and transport, and installation and operation of treatment facilities. In addition, benefits from recycled goods equaled to the total value of recycled goods subtracting the costs of collection, transport, selection and processing of the recycled goods. If those calculations were included in the outcome of Seoul’s VBWF system, Seoul had created economic benefits of 96.1 billion KRW by reducing the costs in waste collection, transport and treatment and by creating market value of 6.1 billion KRW with the recyclables.

Challenges and Solutions

1) Supply of Collected Recyclable Waste

Recyclable wastes are categorized into papers, plastic containers, scrap metals (including can) and glass bottles. The VBWF system, which stipulates collection of recyclable goods for free, helped settlement of the separated discharge and collection of recyclables in a short period. In the meanwhile, recyclables had not been well utilized, which became the burden of the government. In particular, main headache was how to make use of plastic containers (made of PE, PP, PS or PVC) except PET. Even though they are designated as recyclables but those recycling infrastructure for plastic materials was inadequate. Moreover, as VBWF system virtually focused on charging plastic containers, producers were not responsible for the recyclable waste. The deposit-refund system was in place, which levied a refundable container deposit on consumers. However, that system applied to only a few limited items including paper pack, PET bottles, iron can and glass bottles. Unfortunately, many producers gave up on the deposit, so the deposit-refund system did not really help supply and utilize the recyclable wastes.

Solutions

First of all, when it comes to the problems in the plastic containers, government offered loan on installation and operation of plastic recycling facilities to the manufacturers.
In addition, products manufactured using recycled plastics were preferentially purchased by the public sector. Also, in 2003 expanded producer responsibility (EPR), replacing the deposit-refund system, was imposed on the manufacturer to resolve insufficient recycling infrastructure for recyclable wastes (including plastic containers), which held the manufacturer responsible for the costs of managing their products at the end of life. Also, the items subject to the EPR have been expanded to include paper pack, plastic containers, scrap metals (including iron can), glass bottles, big and small home appliances, discarded florescent lamps, and used batteries. As a result, the issue of supply and demand of collected recyclable waste had improved dramatically.

2) Food Waste

Difficulties in Implementing VBWF System

Even though the VBWF system had been in place, food wastes were discharged into standard food waste bin in most autonomous districts and flat rate was levied on each household regardless of the amount discharged. Some district collected free of charge not to use VBWF bags. That’s because VBWF bags made of PE (polyethylene) could function as foreign matter while the food waste is processed into animal feed and fertilizer, deteriorating product quality, which became main reasons the consumers are reluctant to purchase.
Also, autonomous districts had hard time in arguing whether it’s proper to impose charge on food waste which would turn into resources, while recycable items were collected free of charge.

Solutions

The Seoul Metropolitan Government (SMG) has instituted VBWF systems for food waste since 2013 with the goal of reducing food waste taking into account the difficulties in turning the food waste into resources and the hardships in applying expanded producer responsibility (EPR) and the generation of too much food waste.

Considering relatively heavier weight of food waste, the government has recommended authorities to adopt weight-based waste fee (WBF) system instead of volume-based system and the WBF system has reportedly reduced the food waste by ten to thirty percent. Under the WBF system, the discharged weight of food waste is recorded for each resident and the fees are levied based on the weight tracking record. The devices for WBF system has been installed only in some apartment complexes as it is costly to install and operate weight measuring devices and enough space is necessary for the installation of device. Detached houses and restaurants have widely used VBWF bags for food waste or standard waste bin tagged with chip.

Foul Odor from Food Waste

Throughout the first year while VBWF system was in place, there had been significant amount of complaints on foul odor in many places including roads leading to the landfill facilities and waste management facilities. The foul odor was created from the food waste and it got even more serious since the VBWF system had been introduced. That was because papers which used to absorb leachate and the foul odor from the food waste were separately discharged in accordance with VBWF system.

Solutions

The problem of foul odor had been resolved by a massive change in the food treatment system whereby food waste have been separately disposed, collected and treated. Since 1998, the SMG has embarked on the construction of food waste treatment facilities, has secured and run 5 public food treatment facilities and also has commissioned private facilities for the food waste treatment. Starting in 2005, direct land-filling of food waste has been banned.

3) Waste Bags

Material

Broken glasses and small-size construction wastes are sharp and heavy, often causing injuries to the sanitary workers particularly during collection procedure.

Solution

Since 1997, special VBWF bags have been manufactured especially for wastes, which both discharger and collectors find hard to handle, including broken glasses, small-size construction wastes and etc. These bags are made of durable ‘poly propylene.’

Environmental Issues

VBWF bags, the essence of VBWF system, is very convenient especially in big cities like Seoul as the system naturally imposes fee in proportion to the amount of generated wastes. However, many had pointed out whether it is proper to use the throw-away type VBWF bags.

Solution

As a way to resolve this, government recommended shopping giants including E-mart, Homeplus, Lotte mart, Nonghyup, Hanaro club, Mega mart to sell VBWF bags as shopping baskets instead of free plastics bags so shopping giants in Seoul started to follow government’s recommendation. These VBWF bags are called as reusable bags which are also used as shopping baskets in addition to its original use as VBWF bags. The prices of reusable VBWF bags are the same with those of ordinary VBWF bags.

4) Negative Public Sentiment against the Implementation of VBWF System

VBWF system had been instituted with the strong support of government, cities and some academics who felt sense of crisis due to the difficulties in securing sites for waste treatment facilities, not with the support of the general public. After all, VBWF system is quite inconvenient program to the perspective of citizens, the dischargers, and many experts argued that other nations would not introduce the VBWF system for fear of reckless illegal dumping.

Solution

In order to overcome such a negative social atmosphere against the VBWF system, authorities had made enormous efforts to get rid of institutional stumbling blocks and explored benefits and effects as well as possible problems, and thereby secured a chance to persuade general public.

- Thorough Preparation
It is imperative to figure out what type of VBWF system is proper for the city during the preparation stage. Seoul selected VBWF bags as a means to measure the waste volume because it’s hard to identify dischargers in this overpopulated but cramped city with lots of high-rise buildings such as apartment complexes and shopping malls.
However, it could be desirable to use waste bins for area with lots of detached houses and with roads stretching in all directions. Also, the use of waste bins could prevent the waste of throw-away VBWF bags, ward off illegal dumping by concluding contracts with the dischargers on the size of trash bins, and save waste collection fees by using automatic loading system.

- Cooperation with Civic Groups
In the settlement of VBWF system, civic groups in the environmental field had played a crucial role. While the introduction of the VBWF system had been discussed, civic groups were not by and large positive to the idea. They were also worried about fly-tipping not to pay charges for the wastes and were doubtful of government, arguing the government tried to shoulder the entire burden of waste reduction and turning the waste into resources to the general public. However, the civic groups started changing their attitude after they participated in the pilot projects and site monitoring in the year when the VBWF system was introduced, and ascertained publics’ passion for the system. The civic groups had steadily partaken in pilot project evaluation, year one evaluation, year two evaluation, and ten year evaluation. Even nowadays, they have taken part in the progress evaluation of volume-based food waste fee system. Positive attitudes and evaluation of civic groups have made a huge contribution to changing the tone of media coverage and the public awareness of the issue.

5) Illegal Dumping

When introduction of the VBWF system was considered, one of the most worrisome side effects was illegal littering not to pay waste collection charges. As worried, some threw away municipal wastes or business waste into public trash bins on the street, disposed of waste in remote area, or discharged waste in non-VBWF bags.

Solution

In order to prevent littering, some local authorities installed reflectors in vulnerable places, made flower garden, got rid of public waste bins in the down town. Due to such a series of efforts, the number of violations had been dramatically decreased, even though not perfectly eradicated. In addition, penalties were imposed on the violations or VBWF bags were offered to low income family free of charge.

6) Legal Framework for the Institutionalization of Volume-based Waste Fee System

- Legal Grounds for the Volume-based Waste Fee System
Legal grounds for volume-based waste fee (VBWF) system is ‘Waste Management Act’ and specific implementation of the act is determined by regional authorities’ ordinances. The Waste Management Act includes penalties against the violators.

Each regional authority’s ordinance defines specifics of the implementation which are types of waste subject to the VBWF system, ways of discharge, charge, color and materials of standard plastic bags (VBWF bags), safety management of manufacturing and inspection of VBWF bags, how to designate shops in charge of supply, purchase and sales of the VBWF bags, rules the seller have to follow, the standard of cancelling the designated VBWF bag sales shops.

The size, material, strength and type of the standard litter bags are determined by Korea Federation of Plastic Industry Cooperation (KFPIC). The standard VBWF bags should be manufactured in accordance with the standard of KFPIC and if they fail to meet the standard, they will not pass the inspection.

To prevent the manufacturing and use of fake litter bag, seals stamped on the surface of the VBWF bags are kept by local authorities (or collection and transport agency authorized by the local authorities) and are handed over to the manufacturers only when the VBWF bags are manufactured. If fake bags are manufactured or distributed, violators will be subject to criminal penalties equivalent of fabrication of the official documents.

Promotion of Phased Price Rise of VBWF Bags

On August 1 2015, the prices of VBWF bags rose in 4 regional autonomies in Seoul including Yongsan-gu, Nowon-gu, Youngdeungpo-gu, Dongjak-gu. With a 20 liter VBWF bag for municipal solid waste as a basis, the price was previously determined between 340 KRW and 380 KRW but rose to 400 KRW and 490 KRW. With a 2 liter VBWF bag for food waste as a basis, the price has risen to 140-210 KRW from 50-80 KRW. The rise was not confined to a couple of autonomous districts but 14 autonomous districts had already raised the price in the first half of 2015 and other districts also had plans to raise the price.

Table 8. Basic Price of VBWF bags for General Waste and Food Waste

Category		Collection & Transport Fee	Treatment Cost	Manufacturing Cost	Sales Profit	Total	Deviation
General Waste	20L (Basic Price)	402	190	51	22	665	1.00
General Waste	20L (Currently)	308	12	21	22	363	0.55
Food Waste	2L (Basic Price)	142	149	10	4	305	1.00
Food Waste	2L (Currently)	101	5	10	4	120	0.39

Seoul had good reasons to raise the price of VBWF bags. Above all, Seoul residents’ share of charge included in the price of VBWF bags had been lowest among local autonomies. It cost 665 KRW to dispose of 20 liters of MSW while the price of 20 liter VBWF bag was 363 KRW, which meant Seoul residents paid only 55% of the waste treatment costs. In regards to food waste, situation was even more worrisome. The price of 2 liter VBWF bags for food waste was 120 KRW while the food waste treatment costs for that volume was 305 KRW, residents took only 39% of the cost burden.

Table 9. Nation-wide Average VBWF Bag Prices

(20ℓ, 2014 )

Category	National Average	Average of Metropolitan Cities	Seoul	Busan	Dae-gu	In-cheon	Gwang-ju	Dae-jeon	Ulsan
Price (KRW)	457	650	363	850	430	620	740	660	600

While national average price of VBWF bags was 457 KRW, the price in Seoul was 363 KRW, 80% of national average or the lowest in the nation. Even if we factor into different processing methods and costs for local autonomies, VBWF bags in Seoul were apparently cheaper than in other regions.

As the residents’ share of waste treatment cost was low, district’s financial strain got severer. While the price of VBWF bags had not changed a lot since 1995 (the year the system was introduced), prices kept rising, causing bigger treatment costs. In addition, profits from the sales of the VBWF bags have had a direct impact on the district’s financial condition as starting in 2015 sales profits of the VBWF bags have been directly managed by the districts.

Table 10. Guidelines in the Price Raise of VBWF Bags

Category	Current Fee	Autonomies’ Average	’15	’17
General waste (20ℓ)	340KRW～400KRW	363 KRW	437 KRW	492 KRW
Food waste (2ℓ)	40KRW～160KRW	120 KRW	133 KRW	187 KRW

To resolve such problems, Seoul announced guidelines in the price rise to make different prices of VBWF bags from districts to districts to similar level and in raising the lowest rise of VBWF bags in Seoul in phases until 2017.

In other words, the price of VBWF bags will have been raised gradually and by 2018 the prices of VBWF bags in all the autonomous districts in Seoul would be similar level. Final prices for 20 litter VBWF bags will be 492 KRW and 2 liter volume-based food waste fee bags will be 187 KRW.

To sum up, price rise of the VBWF bags mainly aims to reduce the financial burden of local districts. More fundamentally, it aims to curb waste generation at source.

People would be more discrete in discharging if the VBWF bags are more expensive, or they would go so far as not to generate unnecessary waste in the first place. To curb the waste generation, VBWF system has been instituted and for the same purpose the prices of VBWF have been raised.

Model Cases of Volume-Based Waste Fee System

The model cases in Dobong-gu, Seoul
Separate Disposal and Collection of Recyclable Waste

Dobong-gu (gu, administrative district) came up with 6 different guidelines depending on the housing types. Basically, the waste collection from apartment complexes made independently by residents while those living in ordinary residential area required district office to be actively involved in the collection and disposal of wastes and recyclables.

a) Professional Collection System
Garbage collection team was organized in respective sub-districts, dong, and one cleaning personnel and one driver took a recycling waste collection vehicle together to collect the recyclable waste on the road, joined by an official in charge of waste management from the sub-districts office. In addition, they entered into a business relationship with recycling shops. Professional team members brought necessary equipment and collected recyclable materials and sold the recovered materials to the shops. The profitability was maximized and residents’ involvement increased.

b) Compensation for Recyclable Materials
The Volume-based Waste Fee System represents a right way of waste separation and collection but to the perspective of residents it could be a very inconvenient system. It does not make any sense if the recyclable materials-- which residents separated from trash with much effort -- are to be collected free of charge while residents are asked to bear considerable inconveniences following the system. As compensation (toilet paper) was made for the recyclable materials, residents were motivated to participate and the compensation had a level of promotional effect in a short space of time.

c) Separation of 5 types of Recyclable Waste
Recyclable waste is separated into 5 types (newspapers, scrap paper, milk cartons, bottles, metals) and there are certain ways of discharging the recyclable waste. Collected waste, already separated into 5 types, could be sold at the recycling shops immediately upon collection.

d) Daily Collection Drive in One Single Zone
The one-size-fits-all approach was not pursued to the waste collection based on sub-districts, dong, but flexibility was added to the collection process to ensure adjustment of collection methods and schedules, etc. In other words, they divided the entire sub-district into five zones and focused on the promotional drive and thorough waste collection in one zone a day, not covering the entire five zones in a day. The sanitary workers were ordered not to collect improperly discharged garbage at the door and induced the residents to load the garbage bags onto the waste collecting truck when they hear the signature song.

e) Collection and Selling on the Same Day
As the recyclable materials were collected in the morning and sold in the afternoon, the recyclable waste selection yard were no longer necessary. The recovered recyclable materials, depending on the items, were sold directly to the private recycling shops not only to the public recycling companies. In that way, the profits from the recyclables management were maximized and returned to the residents.

f) Implication
The key drivers for the success were 1)the active involvement of residents who were encouraged to do what they had to, 2) high proceeds from the sale of recovered recyclable materials by relevant administrative authorities, 3) return of the proceeds to the residents, and 4) efforts by the authorities to motivate residents’ participation. To ensure success, intensive educational session was conducted, hosted by the head of district office. On top of that, instead of perfunctory committee gathering, public officials had face-to-face encounter with residents for promotion of the program.
