Landfillbiogas 4.0

EXE designs, builds, and runs plants for the collection of landfill biogas, through an automated regulation of biogas extraction wells.

Switching from manual to automated regulation allows biogas to be monitored and valves to be adjusted at short intervals, permitting the entire system to be adapted to changing conditions inside and outside the landfill.

The regulation logics are designed to increase the collection of biogas and maximize the concentration of methane, so as to avoid its dispersion into the environment and use it for the production of renewable energy.

Result: up to 70% increase in biogas collection.

Software and control models

Our know-how for the management of biogas collection wells has been translated into software capable of providing indications on how to regulate the valves of each well.

The information are collected in monitoring models and displayed through simple and intuitive dashboard, thanks to which it is possible to identify anomalies, malfunctions, and supplying for maintenance interventions.

We also provide models to quantify condensate formation in collection lines and to calculate landfill permeability.

Result: a safer and more efficient plant, with greater control of its operation and lower emissions of biogas and odors.
