Turning Fishing Waste into Sustainable Solutions

Posted

The EcoeFISHent project, part of the Circular Cities and Regions Initiative (CCRI), is addressing one of the fishing industry's most pressing challenges—waste. By repurposing discarded fish byproducts and fishing gear, the project reduces marine pollution while creating sustainable supply chains that support multiple industries.

Turning Waste into Resources

Each year, the fishing industry discards 7 to 10 million tonnes of catch, with fishing gear making up nearly 50% of marine plastic pollution. To combat this, EcoeFISHent has developed six circular value chains, converting waste into high-value products that contribute to food, agriculture, cosmetics, energy, and manufacturing.

Using advanced Themis machines, fish byproducts are transformed into Eco-FISH-powder and gelatine, used in food supplements, biodegradable packaging, fertilizers, and skincare products. Additionally, black soldier fly bioconversion repurposes fish waste into fertilizers, biodiesel, and chitin for cosmetics, providing a cost-effective waste management solution for coastal communities.

Discarded fishing nets are also recycled into polymer-based car parts and sustainable packaging, aligning with European Green Deal targets to reduce plastic waste, which constitutes 70% of marine litter in the EU.

EcoeFISHent’s Six Circular Value Chains

EcoeFISHent’s circular approach spans multiple industries:

  • Biodegradable Packaging – Fish processing byproducts replace conventional plastics.
  • Organic Fertilizers – Nutrient-rich waste enhances soil health.
  • Cosmetics Ingredients – Extracted bioactive compounds add value to skincare products.
  • Soil Conditioners – Innovative bioconversion improves agricultural sustainability.
  • Recycled Plastics – Discarded fishing nets become automotive components and packaging.
  • Food Supplements – High-value nutrition products are derived from fish side-streams.

Scaling Circular Solutions

To expand its impact, EcoeFISHent is developing a Cluster Digital Twin, enabling cities and regions to replicate its circular economy model. This approach helps reduce carbon emissions, enhance sustainability, and protect marine biodiversity—demonstrating that fishing waste can become a valuable resource rather than an environmental burden.
