SmiLe company Cirkulär develops next-gen climate-smart protein

SmiLe company Cirkulär develops next-gen climate-smart protein

Award-winning startup Cirkulär is developing processes that use advanced biotechnology to produce proteins in bulk from biological residues, with minimal environmental impact. The first application is milk protein for use in cheese production. Cirkulär is a new member of SmiLe Incubator.

Cirkulär uses climate-smart biotechnology processes to produce proteins that normally come from the animal kingdom. The company will begin by focusing on cheese, a globally popular product that is also high on the list of foods in regard to emissions of carbon dioxide, a greenhouse gas. Significant levels of carbon dioxide are generated by large-scale livestock farming, animal feed production and cheese-making.

The company's contribution to solving the environmental problems is to produce the milk protein casein using a closed, antibiotic-free process based on fermentation with genetically modified microorganisms. The protein is identical to the casein found in cow milk, but it is produced by microorganisms instead of cows. Biological residues, such as residues from rapeseed oil pressing, comprise the raw materials.

“Our vision is to use our technology to produce various types of proteins in order to sharply reduce environmental impact. We've chosen to start with casein in order to achieve the greatest environmental benefit in the shortest time, given the magnitude of cheese consumption worldwide and the enormous volume of milk required for the production process – one kilogram of cheese requires ten liters of milk," says Eric Öste, co-founder and CEO of Cirkulär.

The quality of today's vegetable-based cheeses falls short compared with the product derived from milk. They usually do not contain casein, the most abundant protein found in milk, that has great impact on the taste and consistency of the cheese.

Circkulär has garnered recognition on several occasions, most recently winning a prize and a place in a European coaching program for startups sponsored by the innovation organization EIT Food. And in the past, the company has received awards from the Swedish Energy Agency, as well as from Vinnova, which has awarded several grants – most recently “Innovative Startup Step 1.”

Eric Öste and his co-founder Sebastian Carreno Correa have attracted cutting-edge expertise and are collaborating with researchers from both Lund University and Chalmers University of Technology. And now the company is developing further under the auspices of SmiLe.

“We are extremely pleased to be SmiLe Incubator members. We are particularly looking forward to having our business model challenged by SmiLe’s experienced coaches, and to broadening our network,” says Eric Öste.

“Cirkulär is a company of great interest with a focus on climate-smart technologies. It's exciting to help shepherd yet another innovation emerging from university-based biotechnology research onward toward commercialization – our coaches and our labs are ready for them, and our broad network can help them to achieve their goal faster," says Ebba Fåhraeus, CEO of SmiLe Incubator.
