쓰레기문제해결을위한시민운동협의회는 2002년 9월16일부터 10월 4일까지 국회, 정부, 1$\cdot$2청사, 16개 광역시$\cdot$도청 등 공공기관을 대상으로 1회용품 사용 및 재활용품 분리 수거실태에 조사를 실시한 바, 공공기관의 사무실이나 회의장에서 여전히 1회용컵이 사용(조사대상 $37{\%}$)되고 있고, 또한 사무실이나 자판기 주변에 분리수거함이 설치되지 않는 등 문제점을 지적하고 있다. 이 결과를 토대로 환경부에서는 전국 600개 공공기관을 대상으로 사무실내 또는 회의시 1회용컵 사용안하기, 자판기에 대한 다회용컵 사용, 사무실 및 자판기 주변에 분리수거함 설치등을 철저히 준수하도록 하는 협조요청을 진행했다. 자판기를 통한 1회용기 배출에 대한 수거 및 재활용문제에 대한 관심이 높아지고 있는 현실에 즈음하여 이번 산업정보에서는 쓰레기문제해결을 위한 시민운동협의회의 실태조사 결과를 게재했다.

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.

부산시 연제구는 주민 혐오시설로 인식되어 있는 재활용집하장을 도심 속의 생태공원으로 탈바꿈시켜 주민들의 자연생태 학습장으로 활용토록하고 있으며 재활용품은 품목별로 배출요일을 정하여 수거하는 등 주민들의 자발적 협조는 통해 모범적인 청소행정을 펴오고 있다.

This study was performed to investigate the recycling activity of solid waste. Three study area were selected, which were Dobonggu in Seoul, Siheung City and Kimpogun. The amount of recycled out of the solid waste generated was between 0.02 kg per capita/day -0.10 kg per capita/day. The recovery rate of the waste paper was 42.7%, which was the highest, followed by glass bottles, cans and plastics. The waste paper was the most important item concerning its weight percentage and amount of sales. It comprised more than 60% in its weight and sales amount out of the total recycled item. Glass bottles placed the second. Amount of sale for the recycled item was less than 5 Won per capita/day, this is very low. The Recycling Drive Association, a private organization was mainly organized by public administrational basis and its activity was simply concentrated on the reclassification of the collected recyclables. Generally, citizen's participation and the member's satisifaction was low since there was no economic incentives. In this paper, some strategies were suggested and evaluated to increase citizen's recycling activity.

This paper studies a joint EOQ and EPQ model in which a stationary demand can be satisfied by recycled products as well as newly purchased products. The model assumes that a fixed quantity of the used products are collected from customers and later recovered for reuse. The recovered products are regarded as perfectly new ones. We also assume that the number of orders for newly purchasing items and the number of recovery setups in a cycle can be mutually independent integers. Under these assumptions, we develop an optimization model obtaining the economic order quantity for newly procured products, the optimal lot size for the recovery process, and the sequence of the orders and the setups, simultaneously. And then a simple solution procedure to find a local optimal control parameter set is proposed. To validate the model and the solution procedure, finally, some computational experiments are presented.

Eco-robot for collecting recycling products is the machine which collects non-industrial wastes such as cans, PET bottles and etc. to reuse them as recycling resources. This eco-robot is operated in the condition that it should compress and hold various products without knowing their geometric shapes and material properties. For this reason reliability problems like malfunction or failure. comes to emerge, but the reliability test conditions to assess its performance and durability have not been founded yet. Therefore in this research failure mechanism of the eco-robot was analyzed and life test equipment which can reproduce actual usage conditions was developed. The compression levels in the life test were determined by measuring the crushing force acting on test products and Furthermore the test specimens which have equivalent shape and material properties with those of cans and PET bottles were proposed by simulating the deformation characteristics so that the actual compression conditions were set up in the test.
