Gasification Chemical Recycling System (Waste Plastic - Chemical Feedstock) - Late 1990s to Early 2000s
The gasification chemical recycling system introduced by Showa Denko K.K. (SDK) emerged in the late 1990s and early 2000s as a response to the dual challenges faced by the Japanese chemical industry: the waste plastic problem and the need to secure stable supplies of chemical raw materials. It is characterized by the fact that it redefines waste plastic as a carbon resource and incorporates it into the production of basic chemical raw materials such as ammonia, instead of focusing primarily on waste disposal. At the time, the Containers and Packaging Recycling Law made progress in recycling, but material recycling was not sufficient to break away from dependence on incineration due to significant quality deterioration and application restrictions. The gasification method can treat any material and any contamination, and it presented a recycling model that does not assume a sorting process. It was evaluated as a technology that symbolized the recycling-oriented society theory
of the time because it shifted the waste plastic problem from a mere processing volume issue to a carbon resource reorganization issue.
