HoSt constructing first MICROFERM+ design agricultural biogas-to-biomethane plant in Guichen, France
HoSt is constructing its first MICROFERM+ agricultural biogas-to-biomethane plant at a cattle farm in Guichen near Rennes, France. MICROFERM+ plants are specially designed for on-farm anaerobic digestion of liquid and solid agricultural feedstock. HoSt acts as one-stop supplier for this turnkey project of which completion is planned in November of this year.
To give farmers the ultimate possibility to use their agricultural ‘waste’ as valuable feedstock to produce biomethane, HoSt developed the MICROFERM+. It is a turnkey solution for an agricultural biogas plant combined with a biogas upgrading system, using membrane separation technology, and plant control system in a single compact and modular housing.
“Continuous development and collaboration engineering allowed us to combine the biogas plant expertise of HoSt and the biogas upgrading technology of Bright Biomethane, which resulted in the design of the MICROFERM+”, says commercial director Jean-Sebastien Tronc of HoSt France.
GAEC DU VALLON
At cattle farm ‘GAEC du Vallon’ in Guichen the construction is at the moment in full swing. When ready, annually a maximum of 7,400 tonnes of mainly cattle manure and maize silage is anaerobic digested to produce 100 Nm3 biogas per hour. In the biomethane system, the biogas is upgraded to 55 Nm3 biomethane per hour and is injected into the gas grid. Included in the plant is an efficient heat recovery system. Thanks to the local available service and maintenance team of HoSt, 24/7 technically expert maintenance and spares service can be guaranteed.
MICROFERM+ BIOGAS PLANT
MICROFERM+ biogas installations are suitable for both liquid waste streams as solid waste streams, which are fed separately into the digester. The MICROFERM+ plant is designed to annually anaerobic digest about 5,000 to 10,000 tonnes of feedstock to produce a maximum of 550,000 Nm3 biomethane. Left over digestate, the remaining material after the anaerobic digestion process, can be separated or directly stored in an after-storage, to be used as organic fertilizer for crops.
