About
Founded in 2020 in Brisbane, US, Heirloom Carbon Technologies specializes in carbon dioxide removal via Direct Air Capture. The company has undergone strategic developments to scale its operations. In December 2025, Heirloom Carbon Technologies, Inc. raised an undisclosed amount of venture funding from Development Bank of Japan.
Heirloom specializes in Direct Air Capture (DAC) technology, utilizing limestone for carbon mineralization to permanently remove CO2 from the atmosphere. The company operates facilities that capture significant volumes of CO2, with plans for two new facilities in Northwestern Louisiana capable of capturing nearly 320,000 tons of CO2 annually. Heirloom's technology accelerates the natural mineralization process, targeting businesses committed to sustainability who purchase carbon removal credits to offset their emissions. The company primarily focuses on the North American market, especially the United States, as it scales operations aligned with regional net-zero goals.
