Removing 1B tons of CO2 from the air by 2035 by engineering the most cost-effective, scalable direct air capture system MoreLess
Heirloom Carbon is a pioneering startup in the environmental technology sector, focusing on the reduction of atmospheric carbon dioxide (CO2) levels. The company's primary service is the development and deployment of Direct Air Capture technology, a process that extracts CO2 directly from the atmosphere. This technology leverages the natural carbon-absorbing properties of limestone, one of the most abundant rocks on the planet, to accelerate the process of carbon mineralization, transforming CO2 into rock in a matter of days.
Heirloom Carbon's business model revolves around the sale of carbon removal credits, a market-based tool that allows companies to offset their carbon emissions. These credits represent the permanent removal and safe storage of CO2, either underground or within building materials like concrete. The company's first commercial facility, established in 2020, serves as a testament to their rapid technological and business progress.
The startup operates in the growing carbon credit market, catering to environmentally conscious businesses seeking to reduce their carbon footprint. By offering carbon removal credits at a cost of less than $100 per ton of CO2 by 2035, Heirloom Carbon positions itself as an affordable solution for companies aiming to achieve carbon neutrality.
In addition to its environmental impact, Heirloom Carbon also contributes to the green economy by creating high-paying jobs in the environmental technology sector. The company's operations align with principles for responsible carbon removal, ensuring minimal environmental footprint.
