Streamlining Multiple Heterogenous Renewable Supplies to Single Homogenous Supply and Value Streams for Cementitious Binders and Admixtures
摘要
Currently, cement clinker reduction and binder efficiency often involve industrial residues and petrochemical products. However, a more sustainable and climate-friendly option is to replace these with neglected bio-based agricultural, aquacultural, and recyclable by-products. This is particularly relevant in developing countries with significant agricultural potential. By utilizing these by-products, we can create a more circular economy and improve livelihoods in local communities. Compared to industrial residues, bio-based resources are more widely distributed in smaller clusters, varying by crop and subject to seasonal fluctuations. To match the performance of established industrial products, these heterogeneous materials must be consolidated into a few larger, homogeneous supply streams. This requires collaborative ecosystems, effective communication, and digital optimisation tools. This paper emphasises Africa’s potential to adopt low-carbon construction technologies and leapfrog traditional methods. It analyses challenges and opportunities; and presents a circular approach to converting bio-based and renewable resources into high-performance concrete constituents. The paper details research on circularity potentials with renewable and recyclable materials, which aims to construct a pilot plant for processing low-carbon materials and utilise artificial intelligence tools to optimise supply chains and value streams.
