CIRCA RECEIVES GREEN LIGHT TO SELL NON-TOXIC, BIO-BASED AND BIODEGRADABLE SOLVENT IN EU
A chiral dipolar aprotic solvent, CyreneTM was developed in conjunction with the Green Chemistry Centre of Excellence (GCCE) at the University of York.
Biotechnology company Circa Group has received authorisation from the European Chemicals Agency (ECHA) to manufacture or import up to 100 tonnes/year of its bio-based solvent CyreneTM in the European Union, after receiving REACH Annex VIII approval.
A chiral dipolar aprotic solvent, CyreneTM was developed in conjunction with the Green Chemistry Centre of Excellence (GCCE) at the University of York. CyreneTM is a two step conversion of waste biomass, produced at Circa’s large-scale prototype plant, built in partnership with pulp and paper company Norske Skog in Tasmania, Australia.

Tony Duncan, CEO and co-founder of Circa Group, said, “Annex VIII authorisation is a major milestone for CyreneTM and we are delighted to have been given the go-ahead to sell CyreneTM in significantly larger quantities in Europe. Safer solvents are urgently required and with CyreneTM, we are also offering a bio-based solution with a unique property set, including viscosity, surface tension and polarities – making it an exciting new prospect for advanced materials. Our next goal is registration of CyreneTM in the US and other jurisdictions will soon follow.”
Established in 2006, Circa Group converts waste biomass into advanced bio-based chemicals with its proprietary FuracellTM process at its prototype plant in Tasmania – a joint venture with Norske Skog. Circa’s developing product portfolio includes biosolvents, flavours and biopolymers, including CyreneTM, an alternative to traditional polar aprotic solvents. By creating renewable chemicals from cellulose, Circa is extracting value from non-food, waste biomass and addressing a gap in the market by providing bio-based, non-toxic alternatives.
