Study Tours - 18th March 2015
Two Study Tours have been organised on Wednesday 18th March - the day before the Exhibition opened
- Morning : GAEC des Buissons, small-scale unit
- Afternoon : AgriBioMéthane, first biomethane injection project in Western France
These visits were organised by our partner AILE, leaving and returning from the Parc Expo La Beaujoire in Nante.
GAEC des Buissons
First Microferm unit in France (HoSt technology), installed on the dairy farm of GAEC des Buissons (120 dairy cows), in operationg since early 2014.
The inputs are exclusively agricultural byproducts (cattle manure, fodder leftovers and straw.). The manure is pumped freshly into the Microferm, because the stable is furnished with a closed floor and slurry scrapers.
The biogas is used for cogeneration
- The heat is used in 3 private houses.
- The electricity output has a capacity of 65 kWe

AgriBioMéthane - visit in partnership with AFG & GDF-Suez
First unit in Western France injecting biomethane in the gas distribution grid.
The project, undertaken by several partners (including GDF-Suez, co-organisators of this visit), involves 10 farmers over 4 farms around Mortagne-sur-Sèvre, near Nantes.
The provide around 15000 tons of manure per year, supplemented by 6000 tons of byproducts and waste from agroindustries (waste from slaughterhouses, poultry transformation, industrial biscuit factories).
Innovation of this project, the first to do so in Western France, the biogas produced is upgraded into biomethane with a PSA process, and then injected directly in the gas grid. Thanks to this, energy efficiency reaches around 83%. The energy injected amounts to 550 000 m3 of biomethane per year, corresponding to about 500 households, or 1500 people.
