Hazardous Waste Treatment Business
Under the hazardous waste treatment business, the Group processes and safely disposes of hazardous waste for industrial companies and medical institutions and charges them waste treatment fees. The Group’s hazardous waste treatment business mainly covers collection, transportation, storage and disposal of wastes such as medical waste and industrial solid waste.
Hazard-free waste disposal aims to eliminate or minimize negative effect that hazardous waste may have on the environment. Landfill and incineration are two of the most common treatment methods for solid hazardous waste. For liquid hazardous waste, common treatment methods include flocculation and purification. Before being disposed of, hazardous waste needs to undergo certain pretreatment methods based on its nature. Common pretreatment methods include physical-chemical and solidification or stabilization.
