Management of landfills

Landfill waste produces significant amounts of methane, a greenhouse gas with a warming potential 28 times that of CO2. To limit the impact of this gas on climate change, policy makers and waste management operators encourage both a significant reduction in the volume of waste going to landfill and better recovery of the methane produced.

Landfills produce large amounts of biogas.

This biogas, the result of the digestion of organic waste in the absence of oxygen (anaerobic), is made up of methane (65-70 %) and CO2. It is a source of renewable energy that can be captured and recovered in the form of electricity, heat for district heating networks or as biofuel. Capturing biogas from landfill sites requires an efficient collection and pre-treatment system. It usually consists of a network for collecting and recovering methane and a power generation unit made up of gas turbine generators of various capacities depending on the size of the site.


Who are our customers ?
Cities, local authorities, and inter-municipal structures


→ The design phase includes the configuration of the landfill site and the facilities for capturing and transporting the methane produced by the fermentation of organic waste

→ The construction phase includes land drainage, the construction of storage cells for non-hazardous organic waste and the installation of the biogas capture network

→ The operational phase covers the treatment of the leachate (residual liquids generated by the percolation of water through the stored waste), as well as collecting and treating the biogas itself

→ Finally, the post-operational phase includes the continuation and completion of the previous phase, to which is added landscaping works aiming at restoring the original appearance of the site.

→ Reducing the environmental footprint

→ Diversifying the energy mix

→ Sustainable alternative to landfill
