On April 13, a symposium on mercury-free transformation of acetylene-based PVC production, organized by CCAIA, kicked off in Urumqi. Attendees included representatives from the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, competent industry and information technology authorities of Xinjiang, major carbide-based PVC producers, and catalyst manufacturers. Relevant officials from the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology briefed on the implementation progress of the Minamata Convention on Mercury and the overall considerations for promoting the mercury-free transformation of the carbide-based PVC industry, and listened to relevant opinions and suggestions. CCAIA’s leading officials introduced the general situation of China′s carbide-based PVC industry as well as the R&D and application of mercury-free catalysts. Enterprise representatives reported on the progress and effects of their mercury reduction work, the application and evaluation of mercury-free catalysts, and the technical and economic challenges in the mercury-free transformation process in light of their own practices. The meeting pointed out that mercury-free transformation is an important measure to advance the green development of the carbide-based PVC industry. It is of great significance for implementing the decisions and arrangements of the Party Central Committee and the State Council on strengthening the prevention and control of heavy metal pollution, fulfilling international environmental conventions, and ensuring the security and stability of the PVC industrial and supply chains. Enterprises in the industry should attach great importance to this work, make early plans, and promote the mercury-free transformation of calcium carbide-based PVC production in an orderly manner.
