Carbon Removal in Building Materials
Converting CO₂ into solid building materials through accelerated carbonation
This project operate three sites in the United Kingdom and together they process over 150,000 tonnes of waste each year which would have otherwise been sent to landfill and produce over 300,000 tonnes of sustainable construction materials.
