Determination of potential replacement of natural carbon raw materials with walnut waste in the reduction process of metal recovery

Purpose: The article presents the research results on the possibility of replacing carbon-based raw materials in recycling or metal production processes. The obtained results will verify the possibility of using biomass material in the metal production process in terms of effectiveness and the impact of the resulting products on elements of research equipment. Experimental confirmation of the possibility of replacing coke or reducing its consumption through biomass materials, thus reducing the creation of a carbon footprint, is part of the circular economy. Undertaking such a type of research aims to verify the thermodynamic analysis and supplement the database that will be used in development work carried out on a larger scale, which may translate into industrial applications in the future. Design/methodology/approach: Thermodynamic analysis of the metal oxide reduction process using biomass raw materials indicates the possibility of their use in non-ferrous metal recovery technology. The results obtained from thermogravimetric tests of biomass make it possible to determine the share of volatile components, which constitute an important element supporting the ongoing processes.
