Recently, various develpomet efforts with waste plastics recycling process have been made. The coke-making process is considered to be suitable as a waste plastics recycling facility, because the process involves coal carbonization in a high-temperature and reducing atmosphere. So the carbonization tests mixed with waste plastics were conducted in laboratory tests and actual coke ovens. As a result, it was clairified that the waste plastics recycling process using coke ovens are feasible, where coke, tar, light oil, and coke oven gas were collected without affecting coke strength. Waste plastics recycling process was started as a chemical recycle technology at Nippon Steel Corporation Nagoya and Kimitsu works in 2000.
