| Use advice for data set | When using this LCA data set, it is crucial to include the background system that includes upstream processes such as crude oil refining and transportation. The data should be used to represent HDPE production in China, supplementing with European data where Chinese data is lacking. It is important to account for the specific electricity mix of the national grid in China as per the reported shares of electric power structure for the year 2020. The ReCiPe method (Europe H/H) should be adhered to for consistency throughout the evaluation. Users should consider 1 kg of HDPE resin production as the functional unit when applying this data set. |
| Technical purpose of product or process | High Density Polyethylene (HDPE) is a versatile polymer used in various applications including the manufacture of plastic bottles, containers, pipes, plastic lumber, and geomembranes, among other plastic products. It is specifically designed to endure harsh environmental factors and heavy-duty handling. |

| 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). |
