Updated: On December 2, 2021, China MEE published the revised Hazardous Waste Exclusion Management List[1]. There are a few changes compared with the consultation version published on September 26, 2021. "Waste water-based drilling mud" is replaced by "waste water-based drilling mud and cuttings". Besides, there are changes to the description of hot dip galvanizing scum and bottom slag, as well as waste generated in the production of seven types of resins.
