The process converts C-6 cellulose into building-block chemicals in one step. The process sequesters carbon, so the company describes it as “restorative”.

Rich Riley, co-CEO of Origin Materials, said: "Earning the USDA Certified Biobased Product label is a significant step in our mission to transition the world to sustainable, carbon-negative materials. 

“With this third-party certification, Origin becomes a preferred supplier of biobased materials to the United States government. And we further strengthen our leadership position in renewable, carbon-negative materials that reduce the need for fossil resources.”

Insulation maker PrimaLoft is teaming up with Origin Materials to develop “carbon-negative, insulating, high-performance fibres”.
