Which well-known companies do hazardous waste treatment in China?

Hazardous waste/solid waste/soil remediation: dongjiang environmental protection, Everbright Environmental Protection, Meg (electronic waste recycling), Jinyuan Co., Ltd. (cement kiln co-processing hazardous waste), high-energy environment (hazardous waste, soil remediation), Beijing Construction Engineering Group (soil remediation), etc. In fact, many of the above companies have multiple sectors of business, and environmental protection companies tend to develop horizontally into the industry, so they have developed or acquired many other sectors of business. You can look for the dangerous network, there are many well-known enterprises engaged in environmental protection industry, as well as Veolia, Sander and Everbright International, which have both water and solid waste. Besides, Hanlan environment also has gas business, and high-energy environment has both water and solid waste (hazardous waste) and soil remediation, so my division is not necessarily accurate.
