Sweden’s Millow Commissions “World’s First” Facility Creating Beef-Like Protein From Mycelium & Oats

Swedish food tech company Millow has commissioned a large-scale facility that will produce a beef-like protein from mycelium and Nordic oats, claimed to be the first of its kind worldwide. The 2,500 m² site, formerly a LEGO production hall, will be able to deliver up to 500 kg of protein per day once fully outfitted later this year, with one of Europe’s most advanced fermentation and food laboratories also housed in the building. The facility was made possible by an initial €2.5 million grant from the European Innovation Council.

Millow’s protein is made using a patented dry-state fermentation process, using oats and mycelium as the only ingredients. The products are rich in complete protein, fiber, vitamins, and minerals, with highly sustainable production methods that significantly reduce energy demand, water use, and greenhouse gas emissions. By repurposing the LEGO facility, Millow has avoided roughly 1,400 tonnes of embedded CO₂, making their platform a sustainable solution for advanced protein production with minimal resources.
