In 2017, INDEREN carried out the expansion works of the biogas plant for the Valois project in Chemin des Rouliers, Senlis, France. In addition, we executed 2 phases of the expansion of the same plant in 2019.

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 design, manufacture and installation of the existing central platform. In addition, we installed the buried pipes for the digester, post-digester, technical building and gas cooling.

Furthermore, in January 2019 the INDEREN team undertook the expansion works of the plant that consists in the installation of two vertical GRP tanks and the assembly and installation in order to adapt it to the existing plant. At the end of July 2019, the technical building was expanded by installing a new mixing unit and substrates pumping.

On the other hand, during the month of October 2019, more expansion works will be done by the INDEREN team in the Valois plant, located in Chemin des Rouliers, Senlis, France.
