Overview — sustainable innovation in mussel farming
The FILL project (innovative net for mussel culture) represents a significant breakthrough for sustainable mussel farming. In response to environmental challenges linked to traditional plastic nets, project partners are developing a new generation of biodegradable, high-performance nets designed for real-world aquaculture use. This innovation provides the mussel farming industry with a practical solution to reduce environmental impact and limit the release of microplastics into marine ecosystems.
An innovation for responsible aquaculture
Cutting-edge biodegradable materials
FILL focuses on the creation of advanced polymer formulations that deliver:
- Robust mechanical strength to support mussel growth
- Controlled biodegradation suited to marine conditions
- Industrial-scale production potential
These materials are developed in collaboration with specialists in biodegradable biopolymers.
Prototype development & real-world testing
Prototypes of the biodegradable nets are manufactured as technical multifilaments and tested in multiple environments, including:
- On mussel stakes in Normandy
- In continuous seawater immersion in Lorient
- At Ubside’s test facilities in Ploemeur
These trials assess durability, mechanical performance, biodegradability, and environmental safety.
Field feedback & continuous improvement
Feedback from participating mussel farmers is integral to refining the net design and optimizing its performance for professional use. This iterative field-informed approach ensures the product meets industry standards.
UBSIDE’s role in driving sustainable innovation
As a key contributor to the FILL project, UBSIDE brings expertise in biodegradable materials and marine environmental solutions. Drawing on experience from the European INDIGO project focused on marine biodegradable devices, UBSIDE leads material characterization, biodegradation monitoring, performance validation in marine conditions, and provides technical support to industry partners.
A collaborative project with strong support
FILL unites a diverse consortium of innovators and industry stakeholders:
- ComposiTIC — Project leader
- SMEL – Synergie Mer et Littoral — Project coordinator
- Filt 1860 — Technical net specialist
- NaturePlast — Biopolymer expert
- CETI — Textile innovation centre
- Comité Régional de Conchyliculture Normandie – Hauts-de-France — Regional Shellfish Farming Committee of Normandy – Hauts-de-France
The project is co-financed by the Brittany Region and the European Maritime, Fisheries and Aquaculture Fund (FEAMPA), supporting the shift toward environmentally responsible aquaculture.
FILL: A milestone for the mussel farming sector
Thanks to FILL, mussel farmers now have access to a solution that combines:
- Technical reliability
