Circular Economy Business Model for Sustainable Urban Construction

CE in the construction sector spearheads the exploration of industrial waste as a pivotal resource for the construction sector, addressing the critical need for sustainable materials. Through meticulous evaluation and experimentation, the project endeavours to uncover avenues for extracting secondary raw materials (SRM) from industrial waste streams, notably focusing on slag. These SRMs undergo meticulous mechanical processing, yielding top-tier aggregates tailored for diverse construction applications, ranging from road surfacing to wall construction.
The primary source of these secondary raw materials (SRM) is non-hazardous industrial waste, specifically black and white slag generated from the furnaces at the Makstil factory during the smelting of scrap iron. Black slag undergoes thorough testing to ascertain its suitability as a lower bearing layer (aggregate for tampon—sub base) and as an aggregate for asphalt mixtures. Similarly, white slag undergoes testing to evaluate its potential use as an additive or substitute for cement in concrete mixtures. These products can be used for revitalization of degraded areas, for asphalting roads, for production of partition blocks for walls construction, etc.
