  • This study was conducted to investigate and analyze the discharge characteristics of recyclable material from S-city, S-district, in order to improve the sorting efficiency in recycling sorting facility. The characteristics of recyclable materials collected were analyzed in three different scopes; source origin, collection and transportation, and sorting steps. The average of recyclable waste generation is $0.121kg/day^*man$. Regional collection period appears to be three times a week, and the density of mixed recyclable wastes showed the average of $202.4kg/m^3$ in the waste collection vehicle. In the analysis into the sorting steps, the average of carrying amount of mixed recycling products is 1,154.6 ton/month, the average of appeared density is $181kg/m^3$, the average amount of separated recycling products is 448.5kg/month, and the density of recycling residue is found out to be $48kg/m^3$. The sorting rate of recyclable material is 38.85% and the percentage of residues is 55.90%. Out of 7,744.8 tons of the total recyclable residues, 4,272.1 tons were found out to be possible recylable materials. As a result of increasing the recycling rate of residues, the encouragement of base-recycling, the automation and retrofit of sorting equipment, and energy recovery from recycling residue were discussed.

  • 현대 디자이너는 사회로부터 다양화와 현대화에 대한 지속적인 요구를 받고 있으며, 한편으로는 자원의 유한성이라는 제한으로 인해 다양화와 현대화와의 모순이라는 현실에 직면하고 있다. 이러한 배경들로 말미암아 재활용품 개발은 현대 디자인에서 중요한 분야로 자리 잡고 있다. 본 연구는 폐기물 재활용품의 모듈형식 디자인에 관한 분석을 통하여 지속 가능한 각도에서의 모듈형식 디자인의 역할과 그 중요성의 의미를 인정하고 모듈형식의 생활용품 디자인에서 나타난 정보를 통하여 재활용품 디자인의 개발방향을 제시하였다.

  • Amid growing interest in recycling around the world, the amount of waste is increasing despite the separate discharge efforts of each household, and it is difficult to find accurate data on recycling household waste. Also, recycling segregation is already settled in our daily lives, but we face a serious problem in which a significant portion of the recyclables collected are re-waste. In this study has been proposed a cash compensation system for recyclables, which is paid cash when the recyclables are washed clean and discharged. The cash compensation system proposed in this study could re-use 100% of the discharged recyclables, resulting in rewards for good deeds for individuals, greater returns for businesses and reduced disposal costs for local governments. In addition, it is expected that the government will be able to secure data related to the recycling of domestic waste, which will contribute to the management of recyclables at the national level.

  • 본 논문은 쓰레기종량제 하에서 가격유인책 및 다른 사회 경제적 변수가 가정의 쓰레기발생과 재활용품배출에 미치는 효과를 분석하고 있다. 개별 가정설문자료를 이용하여 가정의 쓰레기발생과 재활용품배출에 대한 구조적 방정식을 3단계 최소자승법으로 추정하였다. 추정결과 가계소득과 가족 수는 쓰레기발생량에 정의 관계로 영향을 미치며, 재활용품배출량은 가정주부의 시간가치와는 역의 관계를 가지고 교육수준과는 정의 관계를 보이고 있다. 쓰레기봉투가격의 인상은 쓰레기발생량에는 영향을 주지 않고 재활용품배출량의 증가를 통해 쓰레기수거서비스에 대한 수요를 감소시키는 것으로 나타난다. 가정에서 분리수거를 통해 재활용할 수 있는 잠재적 재활용가능량은 정부의 재활용품목의 지정 및 재활용기술에 의해 제한되기 때문에 쓰레기가격의 대폭적 인상을 통해 쓰레기수거서비스의 감소를 유도하는 것은 한계가 있는 것으로 보인다.

  • This paper investigates the impact of an increase in unit price of solid waste collection on demand for alternative solid waste disposal types. I control for other variables affecting the demand and employ both community and time fixed effects models in the estimation of each reduced-form demand functions. Estimation results show that an increase in unit price reduces the demand for garbage bag collection services of non-food solid wastes while it increases the demand for food wastes and source-separated recyclables. These results imply that reduction in the demand for non-food solid wastes collection is mainly achieved by increasing the amount of recyclables and food wastes collected. However, it appears that an increase in unit price increases the total amount of solid wastes generated. This suggests that price incentive effects are offset by the decrease in source-reduction efforts because of feedback effects resulting from the increase in recycling, food waste separation, and illegal disposal of wastes.
