단독주택지역의 재활용품 분리배출을 촉진하는 수거방법 평가

Abstract

It is desirable solid waste flow that all recyclables go to recycle stream and all of discards do to disposal stream. This study aims at looking for recyclable materials collection programs which are effective in stimulating separation activity of recyclables at waste sources, and before doing that, frames an “evaluation tool” to be able to describe how much of recyclables are separated with containing any portion of discards quantitatively according to various recyclables collection methods. The application of this tool to 12 residential districts brings diverse results from each other by districts, which means that there are differences in the degree of source separation respectively. In the meantime, low relevance of the results to recycling rates, used as performance criteria in general, shows fundamental characteristic of the tool proposed in this study that is invisible in recycling rates. 5 kinds of collection programs of recyclables, such as recyclables group, collection point, service charge for discards collection, etc, are adapted to evaluate their potentials for encouraging source separation activity. From comparing different recyclables groups which is designated by local government, 2 or 3 groups seperating methods are effective for source separation, and using vehicles or stations as collection points shows similar effect. Keeping collection frequency of recyclables to equal with that of discards or more also promotes source seperation activity. However, this study couldn't identify the reason why collection frequency of recyclables itself and the difference in waste fee don't have influence on source separation activity. This study could not also consider multiple effects of collection methods in the case, for example, when 2 or more programs are implemented at the same time.
