**When Fermentation Meets Friesland**

Alt dairy is not slowing down. It is splitting into two very different playbooks.

In Canada, Aux Labs just raised $4 million to commercialize its precision fermentation platform for dairy proteins. The company produces casein via precision fermentation and plans to scale using existing brewing facilities across North America instead of building its own plant. Asset light. Faster ramp. Less concrete.

Meanwhile in the Netherlands, FrieslandCampina is leaning the other way. The dairy giant is investing more than €90 million to expand whey protein capacity and modernize production across Bedum, Veghel and Workum. FrieslandCampina Ingredients is boosting its ability to process whey into premium protein for sports nutrition, early life nutrition and medical nutrition, with full capacity expected by 2028. The bet is clear. Global whey protein demand is projected to grow at 7.7% CAGR through 2033, and the company says demand is already outpacing supply.

Zoom out and the backdrop gets interesting. In Europe, plant-based dairy holds a 21% share of the plant-based food market, versus 4% for plant-based meat. Sales volumes of plant-based drinks jumped around 150% between 2015 and 2024.

Why it matters: protein demand is not a fad, it is a volume story. Incumbents are scaling up cow-based whey because the market is pulling hard. Startups are scaling smarter, piggybacking on existing infrastructure. The next wave of dairy will not be cows versus plants. It will be about who can deliver functional protein at scale, fast, and without blowing up the capex line.
