Strictly speaking, paint barrels and paint residues are hazardous wastes, and hazardous wastes must be entrusted to qualified units for disposal. According to the Supreme People's Court (20 13)No. 15, illegal disposal or dumping of hazardous wastes exceeding 3 tons not only constitutes a serious pollution crime. However, there are practical difficulties in implementing it in ordinary families. For example, how many barrels of paint are used for home decoration? Therefore, it is also a good idea for manufacturers to recycle. After all, most manufacturers have this qualification. However, if the quantity is relatively large, it is recommended to entrust a qualified unit to handle it or sign a recycling agreement with the manufacturer, and declare the hazardous waste transfer plan to the local environmental protection department, which is safe.
