Abstract
The treatment of waste is becoming a important social problem. In this situation, various processes for treating waste utilizing characteristics of supercritical water are investigated. As one of such processes, a new oil conversion process in supercritical water has been developed, and a demonstration plant of 1 ton/day capacity has been constructed. We successfully liquefied scrap of plastic materials of electric cable made of cross-linked polyethylene and obtained the liquefaction yield of more than 80%.
