The Norwegian-owned newsprint maker and Melbourne-based chemical technology R&D company Circa Group – headed by well-known industry identity Tony Duncan – are building a commercial demonstration plant at Boyer for Cyrene, a non-toxic and cleaner alternative to conventional solvents. Certified plantation softwood will be used to produce the bio-solvent.

Australia has the opportunity to establish a completely new biochemical industry based on renewable forestry resources and today’s announcement will help maintain the Cyrene project’s first mover status. Cyrene is an environmentally friendly, sustainably produced solvent that has the potential to replace fossil fuel based solvents that are currently used in the pharmaceutical and agrichemical industries around the world. We are very proud of the work being done at the Boyer Mill in conjunction with our joint venture partner, Circa Group, to commercialise the production of Cyrene. Today’s announcement is another very important step.
— Rod Bender, Norske Skog’s vice president of renewables and business development.

MELBOURNE, AUSTRALIA and YORK, UK - 7 December 2017. Tony Duncan, Circa CEO, has been voted the Most Innovative Bioeconomy CEO of 2017 by an international audience of bioeconomy experts.

Only the third recipient of the award, Tony is the second Australian winner – a coup for the world’s smallest continent, quietly proving its prowess in bioeconomy innovation.  

“Agriculture and Forestry have always been key industries in Australia, requiring ongoing innovation to compete on global markets. Promisingly for the bioeconomy, there is also strong support here for more sustainable industries,” explains Tony. “I am surprised and delighted to have been awarded this global accolade, and feel it is a true validation of Circa’s approach and team effort over the last nine years.”

Circa defines innovation to include both invention and commercialisation – key tenets in their success to date. In 2017 alone, the team established their 50 Tonne per year prototype in joint venture with Norske Skog and sealed a distribution agreement with Will & Co in key markets, while winning Bio-based Chemical Innovation of the Year for Cyrene in partnership with University of York and distributor Merck Sigma; and making it to the top three bio-based chemicals in the UK with Levoglucosenone.

2018 promises to be full of opportunities, with the commissioning of the prototype manufacturing plant, expected completion of their REACH VIII annex for Cyrene and a further string of exciting joint ventures.

“Importantly, this is our success, not just mine. To get here, it has taken dedicated staff, shareholders, stakeholders and partners. This joint approach is key to bioeconomy innovations: a new interdependence between organisations, built on mutual respect, high trust and an ability to look and work beyond next quarter’s results.”
