Veolia manages more than 150 landfills in the world. Its landfill management system can effectively protect soil and underground water and as well as limiting the emission of greenhouse gases by incorporating specifically developed high-dimension landfill technology: impermeable membrane lining, leachate collection and treatment systems, and utilisation of landfill gas, and strict environmental monitoring.

Veolia’s extensive knowledge and expertise include:

Veolia has total control of the communication and coordination of every process at the landfills, from designing at the outset through to construction and operations management so as to achieve a systematic management of landfills.

The application of high-dimension landfill technology conserves land resources by effectively increasing the landfill capacity of a limited space, and significantly enhances the land utilisation as well as extending the service life of an existing landfill. Different from simple waste piling, the high-dimension landfill technology is based on the calculation of hydrogeological conditions and reservoir storage capacity of the site as well as waste stability assessments and landfill operation requirements to ensure the location is optimum for operation.

Some of the landfill sites Veolia operates are bioreactor landfills. By adopting leachate backflows, this accelerates the degradation of waste and increases the methogenicity of a landfill. At the same time, it improves landfill gas productivity and reduces maintenance time following the closure of a landfill.

Landfill gas is a renewable energy. Through the installation of landfill gas collection, purification, treatment and recovery system, landfill gas is effectively turned into heat and electrical power.

All Veolia facilities follow strict internal and external environmental monitoring rules, from the impact assessment stage through to site rehabilitation and in the limiting of greenhouse gas emissions.

Landfilling waste and biogas recovery

Veolia converts biogas, also known as the landfill gas, to electricity and heat as renewable resources.
