| Use advice for data set | When using this life cycle assessment (LCA) data for Quanlin Paper Industry's unbleached cultural paper, ensure that the system boundary encompasses the entire process from raw material collection, preparation, to the distribution channels. This includes straw collection and transport, import wood transportation, pulping process, production of unbleached cultural paper, transportation, and sales, as well as the treatment of wastewater and black liquor. Data is sourced from on-site research at Quanlin Paper Industry, corporate reports, statistics from the Liaocheng City Statistics Bureau, and environmental assessment materials from Liaocheng City Environmental Protection Bureau. The functional unit is 1 tonne of the unbleached cultural paper product. According to the research, chemicals added during the paper production process at Quanlin Paper Industry make up a minimal proportion of the raw materials and do not include bleaching agents; thus, their use and environmental pollution are significantly less, hence the chemical inputs in this aspect are not included in the LCA. |
| Technical purpose of product or process | The described industrial process refers to the production of unbleached cultural paper predominantly used for stationery, books, and office paper. The raw material composition for this cultural paper from Quanlin Paper Industry comprises 80% straw pulp and 20% imported wood pulp. The production process primarily involves papermaking steps such as pulping, impurity removal, refining, beating, preparing various additives, mixing of paper stock, conveyance of pulpy material, pressing, drying, surface sizing, additional drying, calendaring, and reeling into paper rolls. |
