Sidestream

About Sidestream

Sidestream is a Copenhagen-based food upcycling and by-product matching company focused on helping food businesses make better use of edible sidestreams. It works between producers that generate by-products and businesses that can use them, with the goal of keeping valuable food materials in the food system rather than letting them go to waste.

The company positions itself as a practical bridge between supply and demand for ingredients such as spent grains, juice pulp, coffee chaff, coffee grounds, and stale bread. It supports both sides of the market: producers looking for a new home for by-products, and food businesses looking to test and integrate those materials into production.

Core Values

• Circularity: Sidestream is built around recirculating edible by-products back into the food industry instead of treating them as waste.
• Waste reduction: The company emphasizes reducing food loss by finding valuable uses for materials that would otherwise be discarded.
• Practical collaboration: Its model depends on working closely with producers and users to make by-product reuse feasible in real production settings.
• Sustainability-minded innovation: Founded by people with backgrounds in design and sustainability, Sidestream approaches food upcycling as a creative, solution-oriented challenge.

Unique Aspects

• Focus on edible sidestreams: Sidestream specializes in edible food by-products, including brewery spent grain, juice pulp, coffee chaff, coffee grounds, and stale bread.
• End-to-end support: Unlike a pure marketplace, it also handles collection and delivery, reducing friction for both suppliers and users.
• Active pilot projects: The company is already testing applications such as spent grain in baked goods and carrot pulp in alternative meat products.
• Cross-industry ingredient sourcing: Sidestream looks across multiple food sectors to connect one producer’s by-product with another producer’s ingredient need.
