Protein Industries Canada backs beer byproducts into food ingredients

Protein Industries Canada committed C$1.1 million to help Terra Bioindustries and Great Western Brewing Co. turn brewers spent grain into a new ingredient lineup, a sign that beer byproducts are moving from disposal problem to commercial feedstock. The project, announced May 27, 2026, puts C$486,000 from Protein Industries Canada behind a partnership that is trying to prove spent grain can deliver not just a sustainability story, but real function, nutrition and value.

The work is aimed at four products: Terra Protina, a high-protein concentrate; Terra Fibra, a dietary fibre; Terra Choc, a cocoa extender; and Terra Malt, a multifunctional barley syrup. That mix matters because the commercialization test is not just whether spent grain can be diverted from landfill or feed, but whether it can be separated into ingredients that hold up in food systems and earn their place in a formulation.

The first commercial target is Terra Malt, which Great Western Brewing Co. is using in development of a non-alcoholic beer. Protein Industries Canada said the syrup’s low-fermentable sugar content can help lower alcohol production during fermentation, making it directly useful in a process where sugar profile can determine both final alcohol level and sensory balance. That gives the project an immediate technical reason to exist beyond the broader circular-economy pitch.

Rebecca Palmer, Terra Bioindustries’ marketing lead, said the company’s process separates proteins, fibers, sugars and flavor compounds from spent grain so the material can be used more fully while the nutritional or functional qualities are concentrated separately. That separation step is the whole game for spent-grain upcycling: if the fractions are inconsistent, hard to handle or weak in flavor, the economics fall apart fast.

The corporate and policy backers are treating it as more than a niche experiment. Industry Minister Mélanie Joly said the initiative strengthens Canada’s domestic food supply chain and sustainability story. Protein Industries Canada CEO Tyler Groeneveld said it helps Canada make more food at home and create economic opportunities. Great Western Brewing Co. CFO Brendan Halbgewachs said the project could keep thousands of dollars in the business and support local jobs.

The market logic is reinforced by the scale of the raw material. Terra founder and CEO Steve George said there are about 40 million metric tons of spent grains worldwide, much of it still going to landfill or animal feed. AgFunderNews previously estimated that around 70% of spent grain goes to animal feed, 20% to landfill, 9% to composting and less than 1% to alternate uses. That leaves plenty of room, but not much room for a weak product.

If Terra and Great Western can turn spent grain into ingredients that perform in protein foods, fiber systems and beverage applications, this could be a real ingredient pipeline. If not, it becomes another circular-economy idea that sounded better at the pilot stage than it did in the plant.
