The main characteristics of the Refuse Derived Fuel (RDF) and the produced Solid Recovered Fuel (SRF) were investigated in this work. A technological scheme has been developed to produce alternative fuels that can be used in energy-intensive industries, for example, as a replacement fuel during clinker firing. Also, the work proposed an innovative mechanism for extracting raw materials during landfill mining and its application in alternative fuel production. There was an exploration of the extraction of valuable materials from Landfill Mined Residues (LMRs) and their transformation into alternative fuel, thereby contributing to sustainable waste management practices and meeting the energy needs of intensive industries. The work also addresses the issues of waste disposal, which are by-products of combustion products. The environmental feasibility of using Bottom Ash as a substitute component in clay bricks production and the possibility of using ash generated during the gasification of biomass waste as a partial substitute for cement-based materials has been proven. The results of this research will contribute to the most efficient processing of waste and by-product waste, obtaining both environmental and economic benefits. Ultimately, this work can inform the development of strategies and policies to achieve circular economy goals.
