内容简介

Since 1989 in Japan, about 50 million tons of general wastes (urban wastes) have been discharged every year. The annual quantities of waste discharged per capita are going sideways at about 1,100 g, regardless of various longstanding efforts. The disposal of general waste is carried out according to long-term disposal programs approved from local municipalities. In the quantity treated by local governments, about 80% was incinerated directly. On the other hand, the quantity undergoing various intermediate processing treatments (recycling by crushing and separating and rapid composting) and the quantities going to renewable resource traders excluding incineration treatment was 18.3% in 2003 versus 17.3% in 2002. Therefore, the final - disposal quantities were 8.45 million tons, which decreased by 580 thousand tons compared with the previous year.
