For NENT, Suez has designed and built facilities meeting several purposes:
- secure containment,
- landfill gas processing and its transformation into biogas,
- processing of leachate produced by the natural fermentation of waste
- continuous monitoring of the environmental parameters.
NENT is one of the best examples of the recovery and reuse of “green” energy in the world.
A secure containment facility
The cutting-edge system set up avoids:
- the release of methane into the air,
- nauseating smells,
- the risk of leachate overflowing into the water tables.
It incorporates high-density, multi-layer composite coating systems covering the entire surface of the landfill site, complete leachate collection and processing equipment. The latter contains the biogas and the liquid leachate laden with organic matter and trace elements produced by the natural fermentation of the waste.
Landfill gases recovered
The anaerobic degradation of waste in a landfill environment produces biogas. Once collected, this is used as a renewable energy source for heating the leachate processing station. It is also used to generate electricity for the site.
Controlled water management
Water management is one of the key tools in integrating the site into its environment.In case of rains or typhoons, uncontrolled water flow can cause flooding and crop damage.For this reason, SUEZ continuously monitors and analyses many environmental parameters.
