The combustion process

The waste is fed into the waste incinerator, where it is completely burned. The temperature in the incineration chamber is controlled in order to prevent the evaporation of heavy metals and other harmful substances. From the incinerator, the hot waste gases enter the boiler. The waste gases are then cooled, and steam is produced, which is used to produce electricity and heat. The waste gases are filtered before being released via the chimney. The filter removes pollutants such as dust particles and heavy metals. Water vapour, and the gases nitrogen dioxide and carbon dioxide (CO2), are released via the chimney. The emissions are continually monitored to ensure that the permitted emission values are not exceeded, and that the process does not pollute the air we breathe.

Waste delivered from households, municipal activities and industry is converted into energy in the form of electricity and district heating.

After the energy has been recovered, around 20 per cent of the waste remains in the form of ash. The ash is then transported for the sorting and recovery of metals and post-processing.
