INDEREN was the installation company of the 500 kW biogas plant for the Methanaubrac project in Argences-en-Aubrac, France.

In 2018, INDEREN, subcontracted by the EnviTec Biogas engineering company and under its supervision, carried out the construction work on the pipe system and the plant platforms. In addition, we installed all the necessary equipment for the anaerobic digestion process. The biogas plant has a capacity of 500 kW, and is located in Argences-en-Aubrac, France.
