The Lund, Sweden-based company, founded in 2019, uses filamentous fungal cell factories to create sustainable and high-quality bio-based products. By leveraging microbes that can metabolize a wide range of feedstocks, Cirkulär is able to unlock the potential of industrial by-products that were previously considered useless, thus promoting a circular bioeconomy. The company's focus on developing cell factories that produce key ingredients in milk is part of its larger mission to create a more sustainable and environmentally friendly food system.
