The project Bio Méthane Seg plant in France
&
The project Bio Méthane Seg started in 2014 from research into
how to improve the value of slurry and manure from the farm.
The project is a collective of 53 farmers who are carrying out a
biogas recuperation project using biomethane to feed it into the
natural gas distribution network.
The final project includes more than 50,000 tonnes of input from
the 27 plants. In order to better control potential odours and improve
landscape integration, a building has been constructed for
receiving and managing materials.
The plant is constructed by Naskeo Environnement and equipped
with SUMA agitators through their service partner Sycomore Services
in France. The installed agitators homogenise the substrate to
achieve the highest possible gas output. Six OPTIMIX submersible
motors on guide masts and six GIANTMIX long-axis agitators from
SUMA Rührtechnik GmbH are in operation.
In addition to the biogas produced, 80 % of the remaining product,
the digestate, is distributed to the agricultural land. The remaining
20 % is used for composting and recycling for the production of
green manure.
