Sønderborg Forsyning

Utility company in Sønderborg

Sønderborg Forsyning is the local utility company and provides many services, including district heating and collection of garden waste from public areas and private gardens. Our gasification furnace in Sønderborg has demonstrated continuous operation on various biomass fuels, including operation on 100% green waste wood and wood chips mixed with mash (a by-product from brewing process) or with manure fibres (a by-product from biogas production).



Documents low maintenance costs

The furnace produces a significant part of the heat consumed in the local district heating network. The utility also operates grate-incineration heating plants that demonstrate the low maintenance costs of our furnace compared to grate incineration. This is mainly because there is no grate that requires maintenance and because the refractory’s operational environment is designed to be very favourable.
