Abstract

Nowadays, the cycle of manufacturing and consuming plastic materials has resulted in a serious environmental and economic problem, as called ‘white pollution’ in the world. For this reason, disposal of waste plastics has become increasingly a concern and much efforts for recycling waste plastics have been made. Based on the traditional method of disposing waste plastics by coking process,a new method of cocoking waste plastics and blend coal was proposed by Shougang Group and investigated theoretically and experimentally. The results showed,that the new method not only can increase the content of waste plastics to ≤4% in the charge of coke oven, but also improves the quality of coke if the content of waste plastics ≤2%. The new technology has been proved economical and environmentally friendly to deal with ‘white pollution’.
