Circa Group has received authorization from the European Chemicals Agency (ECHA) to manufacture or import up to 100 tones/year of its bio-based solvent Cyrene™ in the European Union, after receiving REACH Annex VIII approval.

Cyrene™ : An Alternative to Polar Aprotic Solvents

Circa has received authorization from the ECHA to manufacture
or import Cyrene which is a chiral dipolar aprotic solvent

A chiral dipolar aprotic solvent, Cyrene™ was developed in conjunction with the Green Chemistry Centre of Excellence (GCCE) at the University of York. Cyrene™ 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.

Cyrene™ provides a safer alternative to these polar aprotic solvents facing regulatory pressure worldwide and is available through Circa’s distributors Merck/Sigma and Will&Co.

Restricting the Possible Toxic Solvents

Solvent regulation is increasingly focused on restricting hazardous chemicals to manage their risk to people animals and the environment. In the EU, widely used solvents such as NMP, DMF and DMAc are on the candidate list of Substances of Very High Concern (SVHC) due to their reprotoxicity.

In addition, a new restriction on NMP was adopted earlier this year, meaning that after May 2020, use will be further restricted and it will not be able to be manufactured or used in the EU unless operational conditions are maintained to ensure that exposure to workers is below specified levels.

Crossing a Major Milestone

Tony Duncan, CEO and co-founder of Circa Group, said, "Annex VIII authorization is a major milestone for Cyrene™ and we are delighted to have been given the go-ahead to sell Cyrene™ in significantly larger quantities in Europe.

Safer solvents are urgently required and with Cyrene™, 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 Cyrene™ in the US and other jurisdictions will soon follow.”
