Part of the Waste-to-Energy concept

Household Waste

The household waste must be sorted before it is suitable for biogas production. The residual product in the form of packaging is disposed of in the incineration plant, while the organic material is sent to the biogas plant.

Industrial Waste

Organic waste from food production is supplied to the biogas plant. Industrial waste may also include residual material from sewage treatment plants.


Organic waste from agriculture, such as manure and residues from agricultural production are supplied to the biogas plant.

The Biogas Plant

In the biogas plant, the waste products, also known as biomasses, are pumped into the oxygen-free reactors where they are heated. In the reactor a biological process takes place in which the bacteria produce biogas.


Biogas can be used to power a gas engine which powers an electric generator.


Biogas can be used to power a gas engine in a CHP plant, which transforms the biogas into energy in the form of heat.

Biogas and Natural Gas

The biogas is cleaned and can be distributed through the nationwide natural gas networks or used as fuel in the transport sector.


The degassed biomass is used as a fertilizer and soil improver in the fields. The degassed biomass contains all the original nutrients introduced alongside the organic waste.
