| Use advice for data set | When using this data set for life cycle assessment of wood pulp paper production for copy paper, care should be taken to account for all chemistries involved in the pulping and paper-making processes, regardless of their quantities. While typical cutoff thresholds for considering chemicals in assessments are those which mass over 1%, this data set includes all available chemical data, even for those substances used in minor quantities with significant environmental impact. This approach minimizes errors and provides a more comprehensive view of the process. It is recommended that users verify the relevance and timeliness of the data, especially given the potential variance in processes and environmental factors. Any updates on production methods or environmental regulations should be considered. |
| Technical purpose of product or process | The data set representing wood pulp paper production for copy paper is used to quantify the resource consumption and environmental impact associated with the production of 1 ton of copy paper. The process is relevant for life cycle assessment studies and includes pulp making, paper forming, transportation, and waste treatment as its major components. Copy paper produced using wood pulp technology is significant within the paper production industry in Shandong Province, highlighting its importance and representativeness for such studies. The high standards for hardness and brightness in copy paper production justify the selection of wood pulp processes over others. |

| ???common.completenessOtherProblemField??? | Combined with the relevant foreign research on the pulp and paper production process chemicals are usually greater than 1% by mass as a trade-off principle, but in fact some of the chemicals used in very small quantities in their own production process has a great impact on the environment. Due to the difficulty of obtaining data, all available chemical data were analysed in this paper to minimise errors. | ||||
