Graphyte
Combining plant photosynthesis and engineering for large scale, immediate and economical carbon removal
About Graphyte
Graphyte is a carbon removal company that utilizes a process called "Carbon Casting." The method involves collecting waste biomass, such as wood residue and crop hulls, which have captured atmospheric carbon through photosynthesis.
Read full description
This biomass is then dried and compressed into dense, brick-like blocks. These blocks are subsequently buried in specially designed underground sites, where the carbon is permanently sequestered, preventing its release back into the atmosphere for what is estimated to be over 1,000 years. This approach is presented as a low-cost and readily scalable solution for carbon dioxide removal.
The company's business model is centered on selling carbon removal credits. Its primary clients are corporations seeking to offset their carbon emissions, with American Airlines being an early customer. Graphyte operates in the growing carbon removal market, which is a segment of the broader climate technology sector. The company was founded in 2023 and has received backing from investors such as Breakthrough Energy Ventures.
