The pilot

ADEME supported a study aiming to identify deposits and outlets for seashells of Baie de Somme. Following this, the local government carried out a pilot operation for the recycling of seashells from 8 partner restaurants. In the FACET project we wish to investigate the opportunities to use the collected seashells to make products for the tourism sector (e.g. tidal waste collection bins). 

In the pilot we also wish to:

- secure the seashell recovery channel by removing the barriers for a wide use of local shellfish by-products in the tourism sector: regulatory obstacles on the use of biowaste, identification of a competitive process, shift of tourism actors towards circular practices and procurement;

- identify the local actors able to carry out all stages of the recovery process (collection, sanitation, shredding, transformation) and to develop new links between them. This could lead to new collections of seashells generated by touristic actors or during touristic events in Baie de Somme and in Hauts-de-France.

The pilot project addresses upstream, restaurants as shell waste providers and downstream, the local government of Baie de Somme -authority for tourism development- and the tourism sites. It aims at removing the barriers for a wide use of local shell waste by-products in the tourism sector: regulatory obstacle on the use of non-inert waste, identification of a competitive process, stimulation of tourist entrepreneurs in changing to circular practices and purchase.

Origin and objective of the project

There is a lot of consumption of shellfish in the Hauts-de-France region, and particularly in the Baie de Somme territory. The waste from the shells is not currently recovered, and disposed of as municipal waste. For example large volumes of shells are collected from restaurants and fishmongers. These Shells are buried which has a high cost and environmental impact. Meanwhile, the industrial actors involved in the pilot wish to have a more local procurement of shells, as they currently import them from other regions in France and from abroad (Netherlands). This relocation of procurement will help the local economy, and will have lesser environmental impact in terms of transport. As the tourism sector is facing increasing challenges, it shows a strong ambition to have more sustainable activities, and the recovery of waste generated by tourists in restaurants is a step in that direction.

The objective is therefore to have a more local supply with shellfish waste from the Hauts-de-france region and so introduce circularity in the value chain.

Evaluation meetings

Within this pilot evaluation meetings are held with several stakeholders. In this meetings the obstacles all along the local tourism value chain were analysed and discussed. This has allowed setting up baselines.

A first evaluation meeting took place on the 14th of October. This meeting gathered many stakeholders involved in shellfish waste in the Hauts-de-France region (producers, recovery industries, industry associations, etc.), and allowed the actors to meet and present their activities. This first evaluation meeting brought together in total 20 stakeholders from different backgrounds: local authorities, the Hauts-de-France region, Alkern, Ecailles de mer and Etnisi: 3 industrial actors who recover scallop, oyster and mussel shells to make different kinds of products, development agencies. Several of the attendees showed a keen interest in going further and the first contacts were established. Additional discussions helped to gather more information on the actors’ current activities, namely the types of shells produced and/or recovered, the origin of the waste stream, the recovery methods used, the actors’ ambitions for the future and their current barriers. In its next steps, the project will focus on 3 actors in particular: Ecailles de Mer, Etnisi and the Baie de Somme local authority, as it was necessary to limit the scope of the project to the Baie de Somme territory to determine an achievable action plan.

In the second consultation meeting Ecailles de Mer, Etnisi and CA Baie de Somme were invited to discuss the links between their activities.

Collection and recovery of oyster shells from the Dunkirk oyster festival

In addition to the project in Baie-de-Somme, the FACET project facilitated the creation of links between other actors of the Hauts-de-France region, and enabled the collection and recovery of oyster shells from the Dunkirk oyster festival.

The Dunkirk oyster festival is organised every year end of September/early October by the association La Bouée Bleue. It generates approximately 8 tonnes of shells every year. In 2022, the FACET project brought together the Greater Dunkirk Council, La Bouée Bleue and Ecailles de Mer and led to the collection of the oyster shells generated at the festival. The oyster shells were separated from the rest of the waste generated at the event, were collected by the waste services of the Greater Dunkirk Council and sent to recovery at Ecailles de Mer.
