The development of efficient operational techniques and the systematic utilization of landfill gas (flaring, electric power recovery by engines and gas turbines) have sharply increased recovery of the biogas produced by waste. Veolia Environnement's research has invented degassing techniques and an automated tool for managing collection networks called Méthacontrol®, patented by Veolia Environmental Services. It is used to continually regulate the collection network's operation, taking into account various internal and external system parameters. The process, tested under real-life conditions at Claye-Souillly, has yielded conclusive results.
It increased the landfill gas collected by almost 40% compared with a manual adjustment method.
