| 数据集使用建议 | 在使用这个生命周期评估(LCA)数据集时,必须包括包括原油提炼和运输在内的前期过程背景系统。数据应代表中国的HDPE生产,并在中国数据缺乏的情况下补充欧洲数据。根据2020年电力结构的报告份额,重要的是要考虑中国国家电网的特定电力结构。在整个评估过程中,应坚持使用ReCiPe方法(欧洲H/H)以保持一致性。用户在应用该数据集时应考虑1公斤HDPE树脂生产为功能单位。 |
| 产品或过程的技术目的 | 高密度聚乙烯(HDPE)是一种多功能聚合物,用于生产塑料瓶、容器、管材、塑料木材和土工膜等各种塑料制品。它特别设计用于承受恶劣的环境因素和重型搬运。 |

| 时间代表性描述 | 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). |
