Circa Group Information

Circa has developed a proprietary process for the production of a highly flexible platform chemical (levoglucosenone) from waste cellulose. With over 30 years of academic research into its properties, levoglucosenone has had limited commercial uptake due to lack of supply. With our new continuous process successfully proven through 3 scale ups, Circa is now developing a commercial plant capable of supply in tonne quantities. In parallel, Circa is establishing partnerships with specialty chemical manufacturers and researchers to develop new products for the market. This has seen the development of a new lactone flavour (with UNE), and a bio-solvent - Cyrene - (with University of York). Both products are now in trials. Along with these two products, Circa is also working with researchers in UK, France, Australia, New Zealand and Argentina to identify new opportunities and synthesis pathways.
