The technology.

And Beyond.

With a versatile technology platform we engineer fungal cells to customize the next generation of cell factories. For the cost efficient and sustainable production of tomorrow.

From cell to solution

Cirkulär’s technology leverages cutting-edge genetic and fermentation engineering to build customized fungal cell factories. With a keen focus on filamentous fungi, we effectively upcycle industrial side streams, converting underutilized or valueless waste into high-quality bio-based products. Our technology, rooted in the principles of the circular economy, allows us to produce sustainable, cost-efficient ingredients, novel materials, and chemical components tailored to meet diverse industrial requirements.

Through this revolutionary waste-to-value approach, we serve multiple industries, offering custom solutions while reducing our environmental impact. It’s our response to the demands and needs of our customers, consumers, and the planet. It’s an innovative strategy that ensures we are contributing to sustainability and resilience, now and for years to come.

The potential


Our fungal cell factories can produce anything from chemicals and polymers to ingredients, foods and materials.


Filamentous fungi can synthesise a wide range of molecules more efficient than existing commercialized cell factories using bacteria and yeast.


The sturdiness of fungi allows them to grow in diverse environments like cheap raw material from industrial side streams.

Going Cirkulär

Catering to the required customization while fostering scalability – this is circular production the Cirkulär way.


Biomass waste streams and fungal organisms act as input to the Cirkulär system.

Cell factory

With state-of-the art genetic and fermentation engineering we create customized fungal cell factories for various applications.


Utilizing biomass waste streams to grow our fungi provides an efficient, sustainable and cost effective production. To optimize the circular process we set up wall-to-wall production with industrial waste stream providers.


The output of the production is a bio-based, sustainable B2B product. Our first application is Cirkulein – a nutritious and functional mycomeal product for the aquafeed- and pet food industry.
