CIRCA: Two patents filed for new solvenst for CO2 capture process
OSLO, NORWAY - 6 July 2023 - Circa Group AS (stock symbol: CIRCA) has applied
for patents for two new solvents for CO2 capture processes.
As both the interest and the urgency to capture and transform carbon dioxide
(CO2) emissions increases, Circa has developed two new CO2 solvents from its
platform molecule, levoglucosenone (LGO).
The two new solvents named Furatech:1 and Furatech:2 are the product of 12
months of development and testing across a range of new LGO-based molecules
within Circa's R&D team.
The Furatech products have been designed to be used in several current CO2
capture processes and discussions are underway about further optimisation with
our engineering partners.
"Applying for patents is a major step and we are sufficiently excited about the
performance of these two new CO2 solvents that getting protection in place as
quickly as possible is a priority," says Tony Duncan, Circa CEO. "Furatech
testing has shown good CO2 capture performance across multiple cycles, as well
as lower energy requirements in the desorption phase compared to current
With the ReSolute plant commissioning planned for mid-2024, further testing and
trialling of Furatech:1 and Furatech:2 will continue in parallel.
Established in 2006, Circa Group converts sustainable biomass into advanced
bio-based chemicals with its proprietary FuracellTM process. Its developing
levoglucosenone based product portfolio includes bio-polymers and bio-solvents
including CyreneTM. By creating renewable chemicals from cellulose, Circa is
extracting value from non-food, biomass and addressing a gap in the market by
providing bio-based alternatives contributing to a lower carbon and more
