Japan has developed a technology that uses waste plastics as raw materials to obtain useful materials such as chemicals and pharmaceutical raw materials, and is currently conducting research and development in practical use.
According to the “Nihon Keizai Shimbun†report, the method for preparing these useful materials is to heat polyethylene, polypropylene, and other waste plastics to 300° C., decompose them into carbohydrates, and then add catalysts made of germanium and silicon. Synthesis of aromatic compounds such as benzene, toluene and xylene. When reacted at a temperature of 525°C, 70% of the waste plastics can be converted into useful aromatic substances. These substances can be used as chemicals and raw materials for pharmaceuticals, gasoline fuel improvers, etc., and have a wide range of uses. The remaining components can be converted to hydrogen and propane, and 0.5 liters of hydrogen can be produced per gram of waste plastic.
