Addition of new capability recognises growing demand for sustainable chemicals

Nigel Rowe

The bio-chemical manufacturer, Circa, is proud to welcome a new appointment, Dr. Ebbe Dommisse, as Chief Operating Officer. With a PhD in Chemical Wood Processing from the University of Stellenbosch in South Africa, combined with extensive experience in cellulose, pulp & paper, petrochemical and polymer industries enhances Circa’s strong competitive advantage in the bio-chemistry industry.

In his new role, Ebbe will focus on implementation and scale-up of Circa’s proprietary technology for the production of Levoglucosenone from waste cellulose. And with a growing order book from major European and North American companies, developing a pathway to scale is a critical priority for the business. Dr Dommisse will be responsible for the development of Circa’s continuous manufacturing process and the scale-up to meet future demand.

Tony Duncan, CEO of Circa said “Ebbe’s wealth of experience and industry knowledge provides Circa with increased impetus to achieve our vision to be a global supplier of value-added chemicals from renewable feedstocks.
