| Use advice for data set | Data users should ensure to only include the transportation of copper tailings and replacement raw materials within the factory premises for LCA system boundary considerations. The transportation of other raw materials is excluded from the system boundaries. It is also noted that environmental impacts consequent to the production of copper tailing resource utilization products are not to be considered. The LCI results are based on actual production data and field surveys performed in 2019 in Jiangxi Province, with the absence of additional related data from research and databases. Calculation formulas for cement clinker yield factors should be used according to process consumption and emissions for accurate accounting. |
| Technical purpose of product or process | The process is used for the production of cement clinker where copper tailings are utilized as a substitute for clay. This repurposes the copper tailings byproduct as a resource in the cement manufacturing industry. The utilization system is focused on the production of copper tailing waste-based products and is targeted towards businesses that aim to reduce material waste through industrial symbiosis practices. |
