About

Corigin Solutions is a Merced, California biorefinery that uses vacuum pyrolysis to convert agricultural waste (primarily almond shells) into biochar (Corichar), a liquid plant-growth enhancer (Coriphol), and bio-oil. The biochar is sold as a soil amendment and the bio-oil is supplied to Charm Industrial for permanent underground sequestration. The company brands itself as a carbon-removal business and was featured in a January 2026 WRI article on BiCRS suppliers.
