BUSINESS
Founded in 2019 in Lund, Sweden. Cirkulär ferments forestry and pulp industry by-products into fungal protein (mycoprotein) using filamentous fungi, branded as Cirkulein and initially targeting aquafeed. Has operated a pilot facility in southern Sweden for approximately two years. In 2023, partnered with Sylvamo's Nymolla paper mill in a Vinnova-funded pilot. In late 2025, fish raised on Cirkulein reached commercial markets, described as a world first for mycoprotein-fed fish.
