Transforming ash into opportunity: advancing circular construction for a sustainable Europe

Turning wood biomass fly ash into supplementary cementitious material

Pilot product: Alternative supplementary cementitious material
Location: Lyngby
Technology: Base metal removal
Ash type: Wood biomass fly ash
Targeted metals: Ca, Cl, Mg


This pilot demonstrates the that electrodialytic treatment (EDR) can extract Ca, Cl and Mg from wood biomass fly ash to produce 20 kg of materials that complies with regulations for use as supplementary cementitious material (SCM).​ 

Wood biomass fly ash from Vartaverket, Sweden was used as case to upgrade the fly ash from a waste material to SCM, ready for the concrete producers.
