A huge project is being prepared to the east of Nantes. In the coming years, between now and 2030, an “urban ecology pole” must emerge in the Mauves prairie sector. Concretely, the area must accommodate a rehabilitated and enlarged recycling center, an extension of the current waste treatment and recovery center to treat 270,000 tonnes per year (compared to 140,000 today), but also a new wastewater treatment station or even a bio-waste recovery platform.
A large-scale operation led by the metropolis, valued at 366 million euros. Around 11 million will be needed in particular to rehabilitate the site which hosted a landfill in the past, and whose subsoil is polluted with metals and hydrocarbons.
A consultation until December 20
In the meantime, a consultation opens this Monday on this project which represents, for the community, “an opportunity for synergies between future or already existing equipment in the service of the ecological transition”. According to the metropolis, the Prairie de Mauves site has the advantage of offering “a substantial (and unique) land base which allows the reception in the metropolis of facilities essential to the essential needs of the population, this without artificializing new surfaces”.
If the metropolis justifies the approach by demographic growth and new waste regulations (source sorting of bio-waste, extension of packaging sorting instructions, reduction of buried waste, etc.), it undertakes to “enrich the urban ecology reference project and to reduce nuisance as much as possible by taking into account the opinions of citizens and key players in the territory. »
Residents have until December 20 to obtain information and make their contributions as part of the consultation, led by the national commission for public debate. Several public meetings, the first of which is being held this Monday evening, will be organized. The findings will be made public in early 2024.
