Problem
Removing billions of tons of CO2 from the atmosphere is necessary to mitigate the worst effects of climate change. Natural carbon mineralization, where limestone absorbs CO2 from the air, is a slow process that takes years. Scaling carbon removal requires accelerating this natural process.
Solution
Heirloom employs Direct Air Capture (DAC) technology to accelerate the natural carbon mineralization process of limestone, enabling the permanent removal of CO2 from the atmosphere in days rather than years. The company's facilities capture CO2, which is then mineralized and permanently stored underground. This approach leverages the abundance and low cost of limestone to provide a scalable and verifiable carbon removal solution. Heirloom's DAC facilities are powered by 100% renewable energy and adhere to principles of responsible carbon removal, including strong labor protections and community governance.
Target Audience
Heirloom's primary customers are corporations seeking to offset their carbon emissions and achieve carbon-negative targets through verifiable and permanent carbon removal.
