Showa Denko Got a License to Process Industrial Waste, Aiming to Promote Plastic Chemical Recycling

On July 1, 2020, Showa Denko (SDK) (TOKYO: 4004) obtained a license to process industrial waste, and started to accept used plastics which were crushed and molded.

Since 2003, SDK’s Kawasaki Plant, which is located in Kawasaki City, Kanagawa Prefecture, has been operating “plastic chemical recycling business,” a business to recycle used plastics as raw materials for chemicals under the provisions of Containers and Packaging Recycling Law. SDK calls this business “Kawasaki Plastic Recycling (KPR).” We gasify used plastics under high temperature, and decompose them to the level of molecules. Then gasified plastics are converted into hydrogen (low-carbon hydrogen) and carbon dioxide (CO2). We use low-carbon hydrogen as raw material to produce ammonia, and CO2 as raw material to produce dry ice and carbonated drinks.
