Yes, China has regulations on the disposal of used waterproofing materials. According to the 'Environmental Protection Law of the People's Republic of China' and the 'Solid Waste Pollution Environmental Prevention Law,' used waterproofing materials are classified as solid waste. These laws mandate that solid waste must be disposed of in an environmentally friendly manner, prohibiting arbitrary dumping. Specific regulations may vary by region, and local environmental protection bureaus enforce these rules. Disposal methods often include recycling, centralized treatment, or safe landfilling to minimize environmental impact.
