At the advent of the 21st century, mankind is facing a global environmental problem, and the industrial sector is required to take initiatives in the establishment of recycling society for efficient utilization of natural resources. The Japan Iron & Steel Federation, as a voluntary energy-saving action plan, proposed a 10% energy reduction by 2010 with 1990 as the basis. Furthermore, it has put forward an additional 1.5% energy saving by the use of waste plastics as metallurgical raw materials. By laboratory and actual coke oven tests, it was found that waste plastics recycling process using coke ovens is feasible to recover coke, tar, light oil and gas from general waste plastics mixed in coal by carbonization in coke ovens without deteriorating the qualities of coke. Waste plastics recycling process using coke ovens was started as a chemical recycling technology at Nippon Steel Nagoya and Kimitsu works in 2000. Waste plastics recycling equipment with a total capacity of 120,000 t/y is in operating by Nippon Steel Corporation. Using the life-cycle assessment (LCA) methodology, the waste plastics recycling process using coke ovens was estimated. And the process is thought to be effective to reduce CO_2 emission significantly.
