Japanese blast furnace can "eat" waste plastic

According to the principle of recycling plastic waste from container packaging, Kawasaki Steel Corporation of Japan has recently successfully developed a series of process technologies for the use of waste plastics in blast furnaces. If vinyl chloride is contained in waste plastics, it can be dechlorinated using this technology, then solidified, crushed, and converted into similar pulverized coal products. The practice is to place vinyl chloride-containing waste plastics in a solvent heated to about 2000°C. After stirring, chlorine is extracted from vinyl chloride to produce hydrochloric acid for recovery. Dechlorination resin can also be recovered. This technology is jointly developed by Kawasaki Steel Corporation and the Institute of Earth Environment Technology. At present, the development of the process of gas flow, blowing, reduction, and combustion of plastic after dechlorination is progressing smoothly, and industrial experiments are being prepared.
