Abstract

The problems of waste disposal have become major issues in Japan. Japan must deal directly with these issues. In early 1970s, “KOGAI” or environmental pollution already loomed as major problems. A number of technical innovations and systems were proposed to recycle various waste products. Based on those experiences, current situation of urban refuse, waste plastics, scrapped tires and scrapped automobiles in Japan and their challenges toward 21st century are discussed.
