Market Estimation & Definition

Brewers spent grain (BSG) is the solid residue generated after the extraction of wort during the beer brewing process. It mainly consists of barley husks and other grain components rich in fiber, protein, and nutrients. It accounts for nearly 85% of total brewing by-products and is produced in large quantities throughout the year.

The Spain Brewers Spent Grain market was valued at approximately USD 152.92 million in 2024 and is projected to reach around USD 193.42 million by 2032, growing at a CAGR of 2.98% during the forecast period. The steady growth reflects increasing utilization of brewing by-products across multiple downstream industries and the expansion of Spain’s beer production ecosystem.

Market Growth Drivers & Opportunity

One of the key drivers of the market is the increasing beer production in Spain, which directly leads to higher availability of brewers spent grain. Spain is among the major beer-producing countries in Europe, generating a significant volume of brewery by-products annually.

Rising sustainability concerns and the shift toward circular economy models are also supporting market growth. Breweries are increasingly focusing on waste reduction, resource efficiency, and recycling of brewing residues into valuable applications such as animal feed and bio-based products.

The nutritional value of BSG is another important growth factor. It contains high levels of protein and dietary fiber, making it suitable for livestock feed and emerging food ingredient applications. This has created new opportunities in functional food development and plant-based nutrition markets.

Technological advancements in processing and valorization techniques are further expanding application areas. Improved drying, stabilization, and extraction technologies are enabling the use of BSG in bioenergy, bioplastics, and specialty ingredient production.

What Lies Ahead: Emerging Trends Shaping the Future

The Spain Brewers Spent Grain market is expected to evolve significantly due to the growing focus on high-value applications beyond traditional animal feed usage.

One major trend is the shift toward food-grade utilization of BSG. Increasing research and innovation are enabling its use in bakery products, fiber-enriched foods, and nutritional supplements, moving it closer to human consumption markets.

Another emerging trend is the expansion of bioenergy applications. Brewer’s spent grain is being explored as a feedstock for biogas and biofuel production, supporting renewable energy initiatives and reducing environmental waste.

The rise of circular bioeconomy initiatives in Europe is also shaping market development. Breweries and agri-food companies are increasingly forming partnerships to convert BSG into valuable co-products, reducing landfill dependency and improving resource efficiency.

Additionally, technological improvements in storage and preservation are addressing one of the major industry challenges—high moisture content and rapid spoilage. Better logistics and drying systems are expected to improve commercial scalability in the coming years.
