What is methanisation?
Methanisation (or anaerobic digestion) is both a treatment process and a technology for producing renewable energy: biogas. A specific biomass (population of bacteria) developing in the absence of oxygen naturally degrades the organic compounds present in the vinasses and transforms them into biogas.
At REVICO, after extracting the tartaric acid from the vinasse concentrate, the pre-treated vinasse is sent to one of 4 methanisers. The reactor is kept at 38°C for around 3 weeks. The bacteria consume the organic matter and transform it into biogas, which is a mixture of methane (CH4) and carbon dioxide (CO2).

A reference in Charente to promote all form of energies
REVICO, which has been based in Saint-Laurent de Cognac since 1969, is strongly rooted in its territory. The company regularly organises open days and educational visits for the general public, to promote all forms of energy.
The company is fully involved in the Cognac sector and contributes to the environmental and energy progress initiatives proposed by institutions.
REVICO is a player in the circular economy.
