Is industrial rock wool a hazardous waste?

First of all, the full name of hazardous waste is hazardous waste, which refers to the waste with the characteristics of hazardous waste that is listed in the national hazardous waste list or identified according to the standards and methods of hazardous waste identification stipulated by the state. Hazardous waste has five common characteristics, namely toxicity (including leaching toxicity, acute toxicity, biological toxicity, etc.). ), corrosiveness, flammability, infectivity and chemical reactivity. Solid waste with one or several hazardous characteristics is classified as hazardous waste.

Industrial rock wool is an industrial product, not a hazardous waste. According to the national hazardous waste list, waste insulation materials and construction waste containing asbestos belong to hazardous waste. The Catalogue does not indicate that rock wool belongs to hazardous waste, and solid waste with unknown hazardous characteristics should be identified according to the national standards and methods for identifying hazardous waste.

Supplement: The main raw materials of industrial rock wool are high-quality basalt, dolomite and other natural rocks. After melting at a high temperature above 1450℃, it is formed by high-speed centrifugation with an internationally advanced four-axis centrifuge. Add waterproofing agent, etc. After being collected by cotton harvester, it is made by pendulum method, and then the cotton is flattened, solidified and cut. Utterson rock wool does not contain asbestos. Even if there is a fire, it will not release toxic and harmful gases, and will not produce smoke and dripping water. As a biodegradable fiber, it is easy to dissolve and excrete even if it comes into contact with skin or is inhaled into human body. It does not cause cancer, and the leaching toxicity detected according to the identification standard does not exceed the standard, so it does not belong to hazardous waste.
