The processed ash will then be able to replace up to 25% of cement in low-CO2 concrete production.

TransAlta previously secured with Lafarge Canada for the supply of renewable power to its Exshaw, Alberta, cement plant in February 2022.

Australia: First Graphene has partnered with Suvo Strategic Minerals to develop graphene-enhanced metakaolin for use in cement and concrete production.
