BioFaCon3

The BioFACON3 project (BioBased Fly Ash for Engineered Concrete Products) aims to upcycle fly ash generated from biomass combustion in cogeneration plants. These by-products, typically disposed of in landfills, can be used as “Supplementary Cementitious Material” in cement-based formulations.

• The main goal is to make these ashes compatible with cement by studying the effect of undesirable elements such as alkalis and phosphorus.

• An economical and innovative physico-mechano-chemical treatment process is being developed to enhance the reactivity of the fly ash, facilitating its incorporation into mortar or concrete mixes.

• By partially substituting more traditional resources (like blast furnace slag or coal fly ash), this project helps reduce waste generation and optimize resource use in the construction sector.

• The consortium includes Ibv & Cie S.a. (Industrie du Bois Vielsalm), the CTP (Centre Terre et Pierre asbl), and the University of Liège (Urban and Environmental Engineering and Chemical Engineering), working closely together to establish and validate these innovative valorization pathways.
