In 2017, INDEREN carried out the expansion works of the biogas plant for the Vitaligaz project in Étréville, Normandy, France. In addition, we executed the second phase of the expansion of the same plant in 2018.

In 2017, INDEREN, subcontracted by the EnviTec Biogas engineering company and under its supervision, carried out the installation works of the peepholes, the platforms, the agitators in the new digester, as well as the adjustment of the existing central platform. In addition, we installed the buried pipes for the new digester and gas cooling.

Furthermore, in 2018 the INDEREN team undertook the expansion works of the plant that consists in the modification of the biogas treatment system (gas cooling) and the modification of the gas pipeline that powers the CHP engine. Currently, the biogas plant has a power of 2.4 MW and is located in Étréville, Normandy, France.
