Graphyte

Graphyte is a climate-technology company developing Carbon Casting, a durable carbon-removal process. It uses timber and agricultural residues that would otherwise be burned or decompose, dries and compresses them into dense carbon blocks, protects them with an impermeable barrier, and stores them in monitored underground sites. The company says this approach combines photosynthesis with engineering to provide low-cost carbon removal designed to last more than 1,000 years.
