Métha-Vie: a group of 19 farmers committed to bioNGV


Métha-Vie is an important project carried out by 19 French farms, devised 9 years before its launch after a very long administrative procedure. It has been shown that this is the main obstacle to achieving energy independence in countries such as France or Spain, since biogas or biomass environmental projects in other countries such as Germany manage to reduce processing times by a quarter.

Finally, a project of 9 million euros has been launched, contributing 600,000 euros of capital. Several public entities participate in the operation and have extensive bank financing. The plant already invoices 2.4 million euros per year and has around 500,000 euros in operating costs. The plant works 24 hours a day, 7 days a week thanks to its 4 employees.

At Métha-Vie they have been producing biogas and bioNGV since 2021 which they use for the mobility of cars, vans, trucks, buses and coaches. It takes about 60 days to obtain biomethane from the different materials that reach the methanizers. They basically use 2,800 tons of agricultural waste from cereal crops, 1,400 tons of chicken manure, 22,650 tons of cattle manure and waste from a local dairy. Every day some 110 tons of manure come in, supplied by the 19 farms involved. Arrivals are made by trucks that work with bioNGV.

The materials are automatically injected into 8-meter-high stainless steel tanks at a certain rate to optimize the process, which mixes 70% liquid materials and 30% solid waste. Where anaerobic digestion occurs thanks to slow agitation, achieving a biogas that is not flammable at controlled temperature and pressure. At the outlet of the methanizer, and before its injection into the network, the gas is purified and odorized. The plant maintains a production of 270 Nm3/h.

By changing the fertilization of the fields of the 19 farms with manure for digestate, the population has forgotten about the bad smells, something that the nearby populations value very positively.
