The brewer's spent grain market size has grown rapidly in recent years. It will grow from $1.67 billion in 2024 to $1.84 billion in 2025 at a compound annual growth rate (CAGR) of 10.2%. The growth in the historic period can be attributed to rising use of spent grain as animal feed, waste management, integrating brewery waste back into the agricultural cycle, recycling and repurposing material, and providing a nutritional boost to feed.

The brewer's spent grain market size is expected to see strong growth in the next few years. It will grow to $2.69 billion in 2029 at a compound annual growth rate (CAGR) of 9.9%. The growth in the forecast period can be attributed to increases in brewing output, weather conditions and climate change, the cost associated with disposing, increasing consumption of beer and shifts in consumer preferences. Major trends in the forecast period include high-value product extraction, waste-to-energy solutions, smart farming, ongoing research and innovation, and soil amendment or livestock feed.

The rising beer consumption is expected to drive the growth of the brewer's spent grain market. Beer, an alcoholic beverage made from fermenting sugars primarily sourced from grains such as barley, wheat, or corn, is seeing increased consumption due to cultural and social events, economic growth, effective marketing, and evolving drinking preferences. This growing demand results in higher production of brewer's spent grain (BSG), a byproduct of brewing that can be repurposed for animal feed, biofuels, and food ingredients, thereby reducing waste and adding value to the brewing industry. For example, in December 2023, Kirin Holdings Company Limited, a Japan-based beverage company, reported that global beer consumption increased by approximately 5.4 million kiloliters, or around 8.5 billion 633-ml bottles, in 2022 compared to the previous year, reaching about 192.1 million kiloliters. This represents a 2.9% increase from the prior year, equivalent to roughly 303.5 billion 633-ml bottles. Hence, the growing beer consumption is fueling the expansion of the brewer's spent grain market.

Major companies in the brewer's spent grain market are advancing innovative sustainability initiatives to minimize waste, improve resource efficiency, and develop value-added products. These initiatives focus on reducing environmental impact by creatively reusing or recycling byproducts from brewing, supporting sustainable practices, and fostering a circular economy. For example, in May 2024, Heineken France, a France-based brewing company, introduced Project Circle. This initiative aims to enhance circularity in brewery operations and lower carbon emissions. It involves separating brewer's spent grain (BSG) into fibers and proteins. The proteins are refined for potential food applications, while the fibers are used to generate renewable energy. The goal is to significantly reduce CO2 emissions, with the pilot phase targeting a 50% reduction in scope 1 thermal energy emissions. Project Circle supports Heineken's objectives of achieving net zero scope 1 and 2 emissions by 2030 and net zero across the entire value chain by 2040. By creating a closed-loop system, Project Circle contributes to the circular economy and helps decarbonize brewing operations.

In September 2022, Sapporo Breweries Ltd., a Japan-based beer brewing company, acquired Stone Brewing for $165 million. Through this acquisition, Sapporo intends to brew Sapporo-branded beers at Stone’s state-of-the-art facilities in Escondido, California, and Richmond, Virginia. The deal is designed to significantly increase production capacity and address the growing consumer demand for its beers. Stone Brewing, a US-based brewery, also produces spent grain products.
