according to the relevant interpretation of the new environmental protection law, water-based ink belongs to hazardous waste. The cans filled with water-based ink, the cloth wiped with water-based ink and the waste residue after treatment also belong to hazardous waste. It needs a treatment plant with special hazardous waste treatment qualification for final treatment. There is no doubt about this. If you don’t understand, you can call the local environmental protection bureau. They will explain it to you in detail.
