抄録

According to the statistics document which the Plastic Waste Management Institute published, the amount of waste plastics in Japan of 2006 is about 10,050,000 t. 72% of the waste plastics are used effectively. The waste plastics which are not used effectively is 28% (direct incineration or direct landfill). With a surge of the interest to environment such as the prevention of global warming, the effective utilization rate of the waste plastic rises year by year, but improvement of the further effective utilization rate and development of eco-friendly recycling technology are still important to push forward construction of the recycling society. The Containers and Packing Recycling Law was completely enforced in 2000 to aim at the construction of the recycling society. In environment change to surround such a waste plastic, Showa Denko used the gasification technology that was chemical recycling and started a business to produce ammonia as raw materials with a syn-gas provided by a gasification of the waste plastic from 2003.
