Whey boom fuels surge in protein processing expansion

Protein has long been a way for brands to differentiate in the good-for-you space – but as the line between everyday and active wellness continues to blur, standing out in the sports and functional nutrition market increasingly relies on high-quality protein and superior, science-backed nutritional outcomes. All that calls for investment in a robust innovation pipeline where formulation, processing, branding and distribution must be well thought through to land with the right consumer and secure return on investment. Because despite the higher margins high-protein products command – whether that’s in the premium nutrition space or in the grocery store – getting hold of protein is becoming increasingly challenging. That’s particularly true of high-end whey protein concentrates, such as WPC80 and WPI, where manufacturers are having to spend thousands of dollars per tonne of product. In segments such as sports nutrition, the price of whey is the necessary trade-off for access to a high-margin market with resilient demand patterns. And yet, with quantities often booked up months in advance, processors are likely already missing out on deals as demand continues to outstrip supply. For those with the resources and foresight, investment in capacity expansion is already happening. In June, US ingredient producer Actus Nutrition forged a strategic partnership with Darigold to leverage the dairy co-op’s processing infrastructure and supply chain network. The move would unlock value for Darigold farmers while expanding scale and distribution for protein ingredients that Actus offers. “We continue to see strong global demand for high-quality dairy proteins, and this partnership accelerates our ability to meet that demand,” said David Lenzmeier, Chief Executive Officer of Actus Nutrition. “The reliability of Darigold’s manufacturing operations and the quality of its member-owners’ milk make Darigold an excellent partner as we position ourselves to grow with our customers. Together, we are creating a more connected and efficient supply chain that supports innovation and delivers greater value to customers and farmer-owners alike.” “Our partnership with Actus Nutrition allows Darigold to maintain focus on our core business of processing our members’ milk and serving our customers here in the Pacific Northwest and around the world, while participating in the growing market for specialty protein ingredients,” said Amy Humphreys, President and Chief Executive Officer of Darigold. “This partnership brings specialized expertise that complements our strong capabilities and will deliver long-term value for our member-owners.” Whey protein production is one of the growth pillars for the newly merged Arla and DMK, who formed Europe’s largest dairy co-operative last month. The two dairy groups were already running a whey processing JV even before a merger was officially floated, but now, the combined business can leverage DMK’s whey streams to further bolster Arla’s specialised ingredients business. And that’s not all. In May 2026, DMK said it was investing €26m in adding a new WPC80 production plant with a capacity of 7,000 tonnes to its existing plant in Edewecht. Ingo Müller, CEO of the DMK Group, said at the time that the move was designed to secure long-term added value for farmers, in addition to setting the scene for the eventual merger, which has now been formalised. Dutch multinational FrieslandCampina has made premium protein expansion a key strategic priority. The co-op recently acquired Wisconsin Whey Protein , significantly increasing its presence in the US ingredient space, while also doubling production capacity for WPI and MFGM ingredients at its Borculo facility and investing more than $90m across three other facilities in the Netherlands to expand production of WPC80, instantized whey proteins and microparticulated whey. Cheese processor Saputo is also expanding its whey processing capacity to unlock long-term value from its whey streams. The Canadian dairy major has invested more than CA$180m to upgrade its plant in Ripon, Wisconsin, as it seeks to expand WPC80 output by around 35% and improve quality. Taken together, these investments underline how major dairy players are racing to scale high-value whey processing capabilities, positioning themselves to capture sustained growth in premium protein markets while tightening supply continues to support elevated pricing.
