Use of biogas

Methane gas produced in the anaerobic digestion process is collected and stored in a gas holder (see picture).

Methane gas is a combustible material [that may be] used to produce electricity.

Electricity is produced [at the facility] with two units, each with a generator and gas engine having an output of 1250 kW.

The methane gas supplies about 4% of the treatment facility's energy consumption.
This system recycles all of the methane gas produced at the facility to produce energy.

If not for its utilization [in this way], this methane gas would have a negative environmental impact.
