Turning Marine Waste into High-Value Proteins for Food, Feed, and Cosmetics

foodTestedTRL 5

Imagine taking the leftovers from seafood processing and seaweed harvests and using them as 'food' for tiny microbes. These microbes eat the waste and grow into a rich protein powder. It's like turning old scraps into a high-quality protein shake for humans, animals, or even skincare creams.

The business problem

What needed solving

The EU relies heavily on imported proteins, while massive amounts of marine biowaste are discarded. This creates both a supply chain vulnerability and an environmental waste problem.

The solution

What was built

A microbial biorefinery process that converts marine waste into protein extracts and non-protein bio-compounds. Deliverables include 12 total prototypes across food, feed, and pharma sectors.

Who can put this to work

Alternative Proteins
enterprise
Target: Plant-based food manufacturer

If you are a food manufacturer dealing with high import costs for protein sources — this project developed 5 high-quality protein extracts that reduce reliance on imports and use sustainable marine waste.

Animal Nutrition
mid-size
Target: Aquaculture or livestock feed producer

If you are a feed producer dealing with unstable raw material prices — this project developed 5 feed prototypes based on microbial biomass that offer a sustainable and nutritious alternative to traditional soy or fishmeal.

Cosmeceuticals
SME
Target: Bio-based skincare brand

If you are a cosmetic company dealing with a need for sustainable active ingredients — this project developed 3 non-food prototypes and 7 non-protein ingredients like lipids and polyphenols recovered from waste.

Frequently asked

Quick answers

How does this impact production costs?

The project aims to demonstrate a biorefinery that reduces production periods and costs for proteins by using under-exploited marine biowaste as a substrate.

Can this be scaled to an industrial level?

Yes, the project focuses on demonstrating a technically and economically viable bio-refinery for microbial-based protein production.

What intellectual property or licensing is available?

Based on available project data, the project will deliver 6 sets of production guidelines and various prototypes, though specific patent details are not listed.

What is the timeline for implementation?

The project runs from September 2023 to August 2027, meaning results and prototypes will be finalized by late 2027.

How does it integrate into existing waste streams?

It uses a zero-waste approach to upcycle over 30 types of marine biowaste, including invertebrate and macroalgae discards.

Consortium

Who built it

The consortium is highly market-oriented with an industry ratio of 45%, comprising 11 partners across 5 countries. With 5 industrial partners (including 4 SMEs), the project is well-positioned to bridge the gap between academic research and commercial application, ensuring that the 30+ formulations meet actual market requirements.
