Arca’s detailed analysis of feedstock availability has identified 16.5 gigatonnes of carbon removal capacity in suitable historical industrial waste material and this is growing by 1 gigatonne each year due to ongoing operations.
Leveraging this abundant feedstock and the infrastructure of heavy industry enables gigatonne-scale carbon removal, with an ultra-light footprint.
Arca’s portfolio of technologies accelerate the natural process of carbon mineralization to store CO2 permanently as stable carbonate minerals. This is confirmed through direct measurement, sampling, and laboratory analysis.
