The Study on the Possibility of Reusing Landfill Site through BMP Test

摘要

Samples were collected both from upper and lower areas and their physicochemical characteristics were explored while an analysis of biodegradability assessment (BMP) was conducted in Asan. Based on the results, the contents of combustibles were very high. This result enables us to assume that the contents of vinyl and plastic materials of low decomposition speeds were high in the wastes previously introduced on S landfill. Based on the results from analyses of the three components covering water, combustibles, and lime, the highest level of water content was 38.72% in the lower area of A-upper while its lowest level was 29.39% in the upper area of A-lower. Water contents were higher in the lower areas where samples were collected. It can be said that based on the characteristics of a sanitary landfill, there is an impact of shield skirts as leachate treatment facilities in the lower area of a landfill. Anaerobic (BMP test) biodegradability as one of the ways to assess biodegradability of wastes was around 11%, which is lower than that of general wastes amounting to 52.8-78.3%.
