Brewer’s Spent Grain Market Size Forecast: How Big Could The Market Get By 2030?
The brewer’s spent grain market size has experienced rapid expansion over recent years. It is anticipated to increase from $1.84 billion in 2025 to $2.03 billion in 2026, achieving a compound annual growth rate (CAGR) of 10.2%. This historical growth can be linked to the rise in brewing activities, the enhanced availability of spent grain byproducts, the increased application of BSG in animal feed, improvements in grain drying technologies, and a heightened focus on reducing food waste.
The market for brewer’s spent grain is projected to experience substantial expansion over the upcoming years. By 2030, its size is anticipated to reach $2.95 billion, expanding at a compound annual growth rate (CAGR) of 9.8%. This projected growth is driven by several factors including the rising demand for sustainable food components, greater acceptance of upcycled food items, the expansion of plant-based dietary options, increasing investments in solutions for food circularity, and enhanced innovation in food formulations rich in fiber. Key trends during this period involve the increasing application of bsg in human food items, a greater uptake of functional ingredients derived from bsg, increasing incorporation into circular brewing practices, the broadening of high-fiber nutritional uses, and a heightened emphasis on processing bsg for shelf stability.

Brewer’s Spent Grain Market Development Factors: What’s Supporting Demand?
The rising consumption of beer is projected to fuel the expansion of the brewer’s spent grain market moving forward. Beer, an alcoholic beverage derived from fermented sugars typically from grains such as barley, wheat, or corn, sees increased consumption due to cultural and social events, economic growth, marketing efforts, and evolving drinking preferences. This heightened beer consumption directly results in the production of brewer’s spent grain (BSG), a significant byproduct of the brewing process. This versatile grain can be repurposed into animal feed, biofuels, and food ingredients, thereby reducing waste and adding value within the brewing industry. For example, in December 2024, data from Kirin Holdings Company, a Japan-based beverage firm, indicated that total beer consumption in 2023 climbed by approximately 200,000 kiloliters, or 0.1% from the previous year, reaching around 187.9 million kiloliters, with China continuing as the world’s largest beer-consuming country for the 21st consecutive year. Therefore, the growing demand for beer is a primary driver for the growth of the brewer’s spent grain market.

Brewer’s Spent Grain Market Transformation Trends: What Innovations Are Driving Change?
Leading firms within the brewer’s spent grain market are introducing pioneering sustainability efforts focused on waste reduction, improving resource utilization, and developing valuable new products. Such initiatives aim to lessen environmental harm by innovatively repurposing or recycling materials left over from the brewing process. This strategy promotes environmentally sound practices and fosters a circular economy model. An example is Project Circle, initiated in May 2024 by Heineken France, a brewing company based in France. This project seeks to enhance circularity within brewery activities and decrease carbon emissions. It involves separating brewers’ spent grain (BSG), which is the solid residue remaining post-brewing, into its fiber and protein components. The proteins undergo refinement for possible application in food, while the fibers are utilized for producing renewable energy. This method is intended to substantially lower CO2 emissions, with its initial phase targeting a 50% reduction in scope 1 thermal energy emissions. Project Circle contributes to HEINEKEN’s aspirations of achieving net zero scope 1 and 2 emissions by 2030 and attaining net zero across its entire value chain by 2040. Through the establishment of a closed-loop system, Project Circle furthers the circular economy and assists in the decarbonization of brewing activities.
