Process

Rubbish is delivered by waste collection vehicles to the waste pit, then carried on a stoker (combustion system) through the combustion oven and transformed into ash. The ash is discharged while energy contained in exhaust gases from the combustion process is recovered as steam in the boiler and used to drive power generator turbines. The resulting electricity is also available for use outside the facility.
