Secondary raw materials are key in the circular economy. The concept itself is at the intersection of two circular principles: eliminating waste (by diverting waste flows to recycling and recovery plants) and maintaining the value of components. Secondary raw materials also contribute to strategic autonomy and resilience by reducing reliance on virgin raw materials which are not available domestically.

The ECESP website has plenty of examples of secondary raw materials. This series will shine a spotlight on some of them!

Secondary raw material concept: upcycling fish sidestreams into food products

The global fishing and fish farming industry is under pressure from lower quotas, higher taxes and stricter environmental regulations. Although rising prices have sustained profits, the industry urgently needs sustainable solutions to meet the growing demand. With seafood consumption expected to rise by over 50% by 2050, the gap between production and supply is widening, threatening economic stability and food security. A key issue contributing to this gap is the underutilisation of fish sidestreams.

Globally, a significant portion of processed fish - up to 70% in Europe - ends up as low-value animal feed or waste. This is inefficient and economically shortsighted, given the high nutritional value of these sidestreams.

The current approach misses a vital opportunity to maximise resource use and economic potential. The reliance on traditional processing methods results in valuable proteins being reduced to byproducts or waste, while demand for seafood continues to grow.

Converting sidestreams into feed or oil, which sells for minimal returns, contrasts sharply with the potential to create high-quality food products. To address these challenges, the global fishing industry must shift its perspective, recognising sidestreams as valuable resources. Embracing innovative solutions is essential to closing the gap between seafood production and consumption.

Results

• Hailia’s patent-pending technology is transforming the seafood industry by upcycling fish sidestreams into high-quality, versatile food products. It produces items with over 90% fish sidestream content - while being very tasty and suitable for a wide range of dishes, from soups to sushi.
• Hailia collaborates with several Finland-based fish processors as well as global giants, turning previously "wasted" byproducts into premium products.
• The interest in these solutions is immense, validating their approach to sustainable and profitable seafood production. Their partnerships are driving the launch of these products across major markets.
