Market Drivers

Sustainability and Circular Economy Practices

Brewers' spent grain, traditionally treated as waste, is increasingly being repurposed into flour for food applications. Breweries and food producers are adopting circular economy models that transform byproducts into valuable ingredients. This not only reduces environmental impact but also aligns with global sustainability trends, making BSG flour an attractive choice for eco-conscious businesses and consumers alike.

Rising Demand for Nutritional Foods

BSG flour is naturally rich in protein, dietary fiber, and essential micronutrients. Its incorporation into bakery items, snacks, and plant-based products allows manufacturers to meet the growing consumer demand for health-focused foods. The trend of functional foods, which offer added nutritional or health benefits beyond basic nutrition, has particularly boosted the market for BSG flour.
