About
Sitos Group is a California-based biochar producer that uses slow pyrolysis to convert agricultural and municipal organic waste (almond shells, vineyard residues) into durable biochar for soil amendment and carbon dioxide removal. After running a pilot facility at ReGen Monterey from 2023-2025, the company is building a $9M commercial slow-pyrolysis plant in Delano, CA in partnership with Treehouse California Almonds, targeted for operation by end of 2025.
