Process Data set: PVC production;PVC;Carbide Calcium Method (en) en zh

Key Data Set Information
Location CN
Geographical representativeness description Process-based data from China were used, yet if not available, data from Europe were applied instead.
Reference year 2020
Name
PVC production;PVC;Carbide Calcium Method
Use advice for data set When using this LCA data set for PVC produced by the calcium carbide method, ensure to account for the methodological differences between data sourced from China and Europe. Be attentive to the fact that electricity input is modeled based on China's national grid structure of 2020. If the data set cannot fulfill regional specific conditions, it might be less accurate. The ReCiPe method (Europe H/H) should be employed for impact assessment, ensuring methodological consistency. Consider 1 kg of resin production as the functional unit for your assessments.
Technical purpose of product or process The PVC produced using the calcium carbide process is used in various applications in the plastics industry. It can be utilized in the manufacturing of construction materials, piping, cable insulation, flooring, and other PVC-related products that require specific properties imparted by the calcium carbide method.

Time representativeness
Time representativeness description Process-based data from China were used, yet if not available, data from Europe were applied instead. The electricity input was developed based on the national grid structure in China (Table S3), which was obtained from the share of the electric power structure in 2020 (National Bureau Statistics of China, 2020).
