Circa Group’s commercial demonstration plant comes online and produces first batch of 99% pure Cyren

Biotechnology company #Circa Group has announced that its #FC5 commercial demonstration plant is now online, paving the way to a regular supply of Circa’s bio based solvent #Cyrene.

A joint venture between Circa and Norwegian pulp and paper company #NorskeSkog, the FC5 plant is located in Tasmania, Australia. Now successfully commissioned and operated end to end, FC5 is starting to produce a steady stream of 99% pure Cyrene, a non toxic solvent made from certified and renewable cellulose waste.

Cyrene is an alternative to traditional dipolar aprotic solvents, which are used in large volumes – over one million tonnes per year – and are under intense regulatory pressure due their toxicity. In the EU, Circa is a partner on BBI project ReSolve, which specifically aims to replace NMP – a fossil derived solvent which has been categorised as a substance of very high concern (SVHC) under European REACH regulation. Safer solvents are urgently required and Cyrene is a bio based solution with a unique property set, including viscosity, surface tension and polarities. Cyrene is sold worldwide through Circa’s distributors Merck/Sigma Aldrich and Will&Co.

Tony Duncan, CEO and co-founder of Circa Group, said: ‘Scaling up new technologies is always a challenge. After years of hard work, we are delighted that FC5 is now online as this allows us to provide Cyrene reliably and in larger quantities for product testing worldwide, particularly in Europe. Circa is now focused on supporting the development of FC6 – a larger, commercial scale plant.’
