According to the UN, in order to avoid climate disaster the world needs to both reduce carbon emissions and actively remove CO₂ from the atmosphere. Heirloom develops a technology to handle the latter, using limestone to capture carbon directly from the air and permanently store it - and in doing so delivering high-quality carbon credits for businesses to purchase.
Initially, the company stored captured carbon in underground deposits, but it now also boasts the ability to sequester CO₂ into concrete. This process, which was developed alongside its partner, CarbonCure, actually strengthens the concrete, which can then be used in all types of construction projects.
Crucially, because limestone is so widely available - and because the capture process is a chemical reaction - the process requires minimal land and energy. This allows the company to remain relatively low-impact in its operations, making its carbon removal credits more valuable. This has contributed to the achievement of Microsoft purchasing 315,000 metric tons of carbon removal from the company, in one of the biggest deals of its kind to date.
