Confolentais, FR

There is nothing more local than in Confolentais!

Located in western France in the region of Confolentais, Metha Confolentais is a waste-to-energy plant with a biomethane production of around 125 Nm³/h. The biogas is purified and then injected in the local gas distribution grid, thus providing energy for 430 local households! Fed by mainly agricultural byproducts and waste,

the RNG plant utilizes feedstock from a small group of local farmers. The PowerRing technology has the benefit of low operating costs and the ability to treat the entire feedstock mix without any dilution or recirculation, thus providing an optimum basis for future project growth and diversification.
