PVC mercury reduction demonstration project enterprises began to solicit

The reporter learned on September 1 that the "China Polyvinyl Chloride Production Mercury Reduction and Minimization Demonstration Project" jointly developed by the Ministry of Ecology and Environment's Foreign Cooperation and Exchange Center and the United Nations Industrial Development Organization (UNIDO) has now begun to solicit technologies to participate in the project this year.

It is understood that the project was approved by the Global Environment Facility (GEF) in 2017 and launched in the same year

According to the overall design of the project, the project plans to arrange a grant of USD 800,000 to support 2 to 3 waste mercury catalyst recycling and disposal enterprises to carry out technological transformation activities for the environmentally sound treatment of mercury-containing wastes

The goals that enterprises should achieve after participating in the technological transformation of environmentally sound treatment of mercury-containing wastes include: first, mercury recovery rate, ensuring that at least 90% of the mercury in waste mercury catalysts and waste activated carbon can be recovered and reused; second, mercury recycling rate , the mercury recovered and refined from waste mercury catalyst and waste activated carbon should be preferentially reused for mercury chloride catalyst production in calcium carbide PVC production enterprises; the third is the mercury management ledger, and a complete mercury material flow management ledger is established; the fourth is mercury For safe disposal, the mercury-containing waste residues that cannot be recycled should be disposed of in an environmentally sound manner to avoid mercury re-release and secondary pollution
