| Use advice for data set | When using this life cycle inventory (LCI) data, it is critical to only include it for AAC production where copper tailings are substituted for sand and a portion of cement. The appropriate calcium-silicate ratio (w(Ca)/w(Si)) of 0.56 should be maintained. Note that the system boundary excludes the transportation of other raw materials outside the factory and does not account for the potential environmental impacts after the production of the copper tailings AAC product. Actual production data and on-site research from companies in Jiangxi Province in 2019 should be referenced for accurate assessments. |
| Technical purpose of product or process | The use of copper tailings in autoclaved aerated concrete (AAC) substitutes natural sand in the production process, enabling the recycling of copper mining waste into valuable construction materials. This AAC product, utilizing copper tailings, is typically used in the construction industry for building components that require lightweight and good thermal insulation properties, like walls, floors, and roof panels. |
