Graphyte, Inc. is a U.S.-based company specializing in biomass carbon removal and storage (BiCRS). It develops and operates projects that process, compress, and seal biomass residues for long-term underground sequestration, generating carbon dioxide removal (CDR) credits. The company is headquartered in the United States with its initial operations centered on the Loblolly project in Pine Bluff, Arkansas.
Graphyte employs its proprietary Carbon Casting technology to achieve durable sequestration exceeding 1,000 years while emphasizing cost competitiveness and modular scalability. It is privately held, with Breakthrough Energy Ventures as its largest shareholder.
In June 2026, Graphyte established a joint venture with Sumitomo Corporation to develop and sell CDR credits in the United States, with Graphyte holding a 51% stake and Sumitomo 49%. The venture initially focuses on expanding the Loblolly project to an annual capacity of 50,000 metric tons of CO2 removal.
