Oslo, Norway – 22 November 2021

Circa Group AS and the University of York, have signed a new agreement which further extends the close collaboration between the organisations and includes a revised royalty payments schedule and continuing support for the University of York’s Green Chemistry Centre of Excellence (GCCE).

A revenue sharing arrangement for sales of Cyrene™ was originally agreed between the two organisations in 2017. This new royalty agreement replaces that and will see rates reduce from 4% to 1.5% for quantities up to 1,000 tonnes per year, and from 2% to 0. 75% for quantities over 1,000 tonnes.

This is a positive development for Circa, both from a financial and a research perspective. It ensures a continuation of the University’s important and fruitful research into applications for Cyrene™ and the development of other levoglucosenone (LGO) based solvents.

Tony Duncan, CEO and co-founder of Circa Group, said, “The University of York is a highly valuable research partner in identifying LGO derivatives for commercialisation. Circa Group will continue to work with Professor James Clark and the GCCE on development activities to further advance industrially significant renewable chemistry applications.”
