INDEREN was the installation company of the 750 kW biogas plant for the Fertioise project in Coudun, France.

In 2018, INDEREN, subcontracted by the EnviTec Biogas engineering company and under its supervision, carried out the construction works of the pipeline system and the platforms of the plant. In addition, we installed all the necessary equipment for the anaerobic digestion process. The biogas plant has a power of 750 kW, and is located in Coudun, France.

The benefits of the biomethization of the Fertioise biogas plant

  1. This project has gas injection into the natural gas network. After the stage of the biogas, it is injected into the gas network.
  2. Thermal energy is also generated, which will be used to achieve the process of anaerobic digestion and pasteurization.
