Circa creates renewable chemicals from cellulose, extracting value from non-food, waste biomass to produce advanced bio-based chemicals. Our developing product portfolio includes flavours, biopolymers, and bio-solvents including Cyrene™, an alternative to traditional polar aprotic solvents, which is produced in one step from platform biomolecule levoglucosenone.

Cyrene™ is a bio-based solvent that demonstrates circularity, sustainability and safety at every stage of its life cycle. From fossil-free non-food feedstock, to its recyclability and end of life disposal, Cyrene™ is a safer and more sustainable alternative to traditional toxic petroleum-based solvents.

Extensive research worldwide identifies a vast range of bio-based derivatives which can be produced from LGO. Circa has found a way to make LGO at scale, minimising side products, maximising functionality and leading to a breakthrough problem-solving molecule.
