Complex recovery of mineral mining and industrial waste as secondary raw material in the context of eco-conscious building materials and hydrometallurgy

Pressure for new waste-free and CO2-neutral technologies remain high and, in the context of commodity security, the landfills of the past must become the deposits of the future. The objective of the proposed project is the complex valorisation of mineral waste streams, which will be carried out through the development of waste-based building materials and critical raw material resources, as well as the reduction of the carbon footprint based on carbonization technologies. The expected results are basic and applied knowledge (a) the valorisation of local mineral industrial waste as a lightweight building material based on the necessary technical characteristics such as strength and thermal insulation, sound attenuation, durability and environmental performance, and CO2 sequestration; (b) integration of extraction optimized for raw materials with a low Mg content (4-6% MgO) in the key of critical raw material resources into a potentially waste-free ash hill valorisation complex.
