Mixed waste plastics including PVC are decomposed into monomers, hydrogen, etc. at 200°C to 300°C, without organic solvents, using industrial water as a solvent and without precious metals as catalysts, and the world's first depolymerization from PET to methanol (according to our research, by 2023).
Organic wastes such as cellulose, lignin, agricultural waste, sewage sludge, and paper sludge are decomposed into hydrogen and other substances under almost the same conditions as those described above.
