"SolVinge" the Fish and Brewing Waste Problem

An unsustainable future

The aquaculture industry is at a critical juncture. While its rapid expansion is essential to meet the escalating global demand for protein, the industry's current dependence on wild-caught fish for fishmeal is unsustainable. Overfishing has led to the depletion of marine resources, disrupting ecosystems and threatening the industry's long-term viability. The Swedish fleet, harvesting over 120,000 tonnes of pelagic fish as fish meal and wet feed annually, faces significant economic instability due to diminishing fish populations (SwAM, 2021). If current practices persist, key fish stocks may collapse, leading to increased feed costs and rendering seafood inaccessible for future generations.

Concurrently, Swedish brewery industry produces over 4,100,000 hectolitres of beer per year, where brewer's spent grain (BSG) waste likely amounts to 20-25%, much of which is discarded or underutilized, contributing to environmental degradation. The disposal of BSG not only incurs costs but also results in greenhouse gas emissions, exacerbating environmental concerns. This wasteful cycle not only harms the environment but also overlooks a valuable resource that could help address aquaculture's sustainability challenges. By repurposing BSG, there is potential to create a sustainable feed alternative, thereby alleviating pressure on wild fish stocks and promoting a circular economy.

"SolVinge" the problem

By replacing fishmeal with cost-effective, scalable, and circular alternative could reduces pressure on wild fish stocks, securing the future of aquaculture, while cutting GHG emissions, lowering the environmental footprint of both the brewing and aquaculture industries.

As a primarily process technology venture with an innovative waste-to-value model, SolVinge aims to create sustainable, high-value products through developing and scaling proprietary bioconversion process, integrating Black Soldier Fly Larvae (BSFL) cultivation and filamentous fungi for nutrient enhancement. This circular approach not only transforms brewery waste into high-protein fish feed and organic soil amendments but also provides a scalable solution for reducing waste and emissions across multiple industries.

Key monetization streams include the material sales of bioconverted fish feed ingredient and organic soil amendment, targeting organic fertilizer buyers, fish feed mills and pet food companies. Potential future expansion incorporates licensing the process proprietary process (recipe/process patents) to fish feed companies and design and engineering of “So-Labs” modular waste processing systems.
