Wineries, Breweries and Beverages Industry

The anaerobic digestion treatment of wine making effluents requires equipment and processes capable of catering for the substantial changes in volume due to the seasonality of the grapes availability. It also requires processes to pre-treat the high solid matter content of the effluents.

Alcohol and beer production generate large volumes of liquid effluents which can be transformed into renewable energy. The more solid co-products (grains,...) can also be processed in an infinitely stirred anaerobic digester.


Valbio has designed, build and commissioned several anaerobic digestion WWTPs in France processing between a few hundred and a few thousand kilogrammes of COD (Chemical Oxygen Demand, measure of organic matter content) per day in the wine production and bottling sectors. Valbio also has references in the brewery sector.

The implementation of anaerobic digestion for WWT reduces by a factor of 5 to 10 the volume of sludge produced and the energy consumption (compared to an aerobic solution). The producer can simultaneously meet his effluent discharge constraints and benefit from a renewable energy source which he can integrate in his production process. Such is the case in distilleries : anaerobic digestion of distillation vinasse generates biogas used in the distillation process.
