This study was carried out to evaluate the physicochemical characteristics of mined waste(separated waste and soil) and to predict environmental effect of an old landfill site located at north of Seoul. Municipal solid waste(MSW) had been disposed of at the old landfill site used in this study for about 2 years(J990-1992J. The old landfill site selected for this study had accepted mainly muhicipal solid waste. The landfill-mined waste contained separated waste (40.9%) and soil(59.1 %) by wet weight basis. The separated waste consisted of combustible(91.0%) and non-combustible<9.0%). The combustible waste was mainly non-biodegradable plastics. The low heating value of the separated combustible waste, which is calculated by Dulong’s equation, was as high as 3.470kcal/kg. According to the Korean Extraction Procedure, separated waste and soil were proved to be not hazardous. The total content of heavy metal in the separated waste and soil met standard of California State, USA. Therefore the separated waste may be relandfilled at a sanitary landfill site ancvor burned up at an incinerator, and the separated old soil may be used as landfill cover-soil at a sanitary landfill site. Water quality of two streams was grade N, of which water could be used as industrial and agricultural water. The streams near the landfill site might not be contaminated by leachate from the old landfill site. It was estimated that organic matter in the old landfill site would not be actively biodegraded within a short period of time.
