Circa Group is a renewable chemicals company that develops bio-based solvents and intermediates from non-food lignocellulosic biomass. Using its proprietary Furacell process, the company converts cellulose into levoglucosenone (LGO), a versatile platform molecule, and downstream products.
Circa’s lead product is Cyrene (dihydrolevoglucosenone), a bio-based solvent designed as an alternative to traditional fossil-derived polar aprotic solvents such as NMP, DMF, DMAc, and DCM. Cyrene is used in research and industrial applications across areas including pharmaceuticals, battery materials, polymers, and coatings. The company pursues a modular scale-up strategy for production, working with industrial and academic partners in Europe to commercialize its technology and expand capacity. Circa’s activities align with regulatory and market trends favoring safer and more sustainable solvent systems and support the shift toward a circular, bio-based chemicals value chain.
