To ensure the sustainability of his dairy farm, Michel Warzée, farmer and director of Warzée SA, chose to turn to micro-biomethanization.
Thus, Michel embarked on the journey: after a disappointing experience with a manufacturer, he decided to design the installation himself. After six months of reflection, he managed to complete it in just three months.
To minimize maintenance costs, he chose high-quality equipment for essential components (pumps, cogeneration engine, tank materials, etc.). Additionally, to offset these investments, he optimized the installation by integrating heat exchangers and using a system for digestate removal via the principle of communicating vessels, thereby avoiding the need for a pump.
The installation is unique in that it is not connected to the electrical grid, allowing the cogeneration engine to adjust automatically according to the farm’s energy needs.
Since May 2017, the unit has been operating continuously, producing biogas 24 hours a day, 7 days a week.
At the end of 2021, two medium-voltage substations and one medium-voltage cable were installed to connect the farm to Warzée SA. In January 2022, the workshop was connected to the biomethanization installation.
Since the connection, Warzée SA has been exclusively powered by green energy, enabling the company to be completely independent of electricity suppliers.
In the context of the energy crisis we have experienced, this situation provides the company not only with unparalleled peace of mind for the future but also a significant competitive advantage, as it will not be forced to pass on the costs of high electricity bills to its customers.
WARZÉE BIOMÉTHANISATION benefits from co-financing from the EUROPEAN UNION under the European Agricultural Fund for Rural Development (EAFRD).
What is Biomethanization?
Biomethanization is a biological process that transforms organic matter into biogas through the action of microorganisms, in an anaerobic (oxygen-free) environment. This fermentation process is similar to what occurs in a cow’s rumen.
