Grinding wheel foam belongs to which code of hazardous waste?

It is not hazardous waste, but it should be treated as general industrial solid waste.

The solidification of industrial solid waste is generally to solidify the matrix on the waste by adding solidification technology, so that the fixed or dangerous solid waste can be contained in the solidified inert matrix for harmless treatment. When used, the cured product should have good permeability, good mechanical properties, leaching resistance, dry and wet resistance, freeze-thaw resistance and other characteristics.

Grinding wheel foam refers to scrapped grinding wheels used in factories and cannot be reused. Generally divided into brown corundum, white corundum, composite corundum, black silicon carbide and green silicon carbide. There are resin grinding wheels, cutting pieces, polishing pieces and so on.
