Abstract

The EU-funded project, Sustainable Aggregate Production with Imbibed Carbon Dioxide (SAPICO2) is an INTERREG IVa Channel Programme examining the development of eco-construction materials made from various carbonate-able wastes residues normally disposed to landfill. The partnership involves the University of Greenwich (UoG), the University of Picardie Jules Verne (UPJV), and Carbon8 Systems (a UoG spin-out company). The project applies accelerated carbonation technology (ACT) to facilitate waste valorisation in the production of manufactured carbonated materials that have re-use potential. SAPICO2 has investigated more than 100 wastes originating in NW France and the SE UK (Channel Region), with a view to explore new ways in which carbonation can be applied beneficially. Wastes have been collected and characterised for their chemical and physical properties, very importantly for their ability to react/combine with CO2 gas. It is shown that with careful control of a carbonation process reaction conditions it is possible to treat waste to give it value and re-use potential and thus, divert it from landfill into the materials supply chain. Such an outcome meets the needs of the developing European ‘circular economy’. The final part of the SAPICO2 project involved the production of bulk samples of carbonated materials for product testing/evaluation in France.
