On Sept. 23, 2024, China’s Ministry of Ecology and Environment published a draft 2024 edition of the list of waste materials that are not regulated as hazardous waste, as part of the country’s effort to rigorously enforce the Environmental Protection Law, Solid Waste Environmental Pollution Prevention and Control Law and other laws and regulations, optimize China’s hazardous waste identification system, and promote the grade- and category-based management of hazardous waste. Comments on the draft were accepted through Oct. 13, 2024.
Solid waste materials on the list would not be treated as hazardous waste, and would be managed according to non-hazardous waste regulations. The draft list contains 12 types of solid waste, including sludge from drinking, waste from plastic pelletizing, filter residues and sludge from acrylic emulsion production, and waste of ion exchange resins.
