The data set represents the life cycle inventory (LCI) results of calcination of raw materials. This process is typically used in the production of materials like cement, lime, or alumina, where it is essential for transforming specific minerals by thermal decomposition. Users of this data set should account for the specific boundary conditions of the calcination process, including the origin and type of raw material, energy consumption, and emissions. The results should be carefully integrated into broader LCA studies, considering the impact of transportation, potential for recycling of by-products, and regional differences in technology and energy supply.
