Initiated in 2019, Coop d’Herbauges and Nature Energy’s project to build a giant methanizer in Corcoué-sur-Logne has been rejected by the Loire-Atlantique prefecture. The plan was to convert around 500,000 tonnes of organic matter into biogas annually, making it one of France’s largest biogas plants.
Mobilization and opposition from local residents
The local opposition played a key role in this decision. Public inquiries revealed strong resistance from local residents and stakeholders. The main reasons for this opposition were the lack of consultation on the project and concerns about road safety due to the expected increase in truck traffic.
Environmental and agricultural issues
The debate surrounding the methanizer has highlighted crucial questions concerning methanization and its impact on agriculture. Concerns were raised about prioritizing the production of materials for methanization to the detriment of food farming. This situation has led to calls for regulation and stricter controls by the authorities.
Methanizers in Loire-Atlantique: a mixed picture
Loire-Atlantique already boasts 19 methanization units, with a further six under construction. Unlike the rejected project, these facilities were built with the agreement and support of local communities. These projects aim to diversify energy sources while providing farmers with additional income.
Reactions and political implications
Michel Ménard, Socialist President of the Loire-Atlantique département, welcomed the abandonment of the project. At the same time, Hervé Morin, President of the Normandy Region, criticized the excesses of the methanization system, particularly in the cultivation of corn, and announced the suspension of all new funding pending government controls.
The rejection of the giant methanizer at Corcoué-sur-Logne underlines the need for balanced sustainable development that respects both environmental imperatives and the needs of local communities. This decision could serve as a precedent for other projects in France, underlining the importance of a holistic approach to the development of renewable energy.
