Heating through Waste Management

Stikkord: Stasjonær energi i bygg, Energikilder, Energiforsyning, Porsgrunn

35 buildings in Porsgrunn are connected to a district heating plant run by Skagerak Varme (Skagerak Heat) and based on waste heating from Yara’s compound fertilizer factory in Herøya. The plant also provides heating to city streets and a soccer field. In 2007, energy gains from district heating were equivalent to a 6000 ton cut in C02 emissions.

Among the 35 buildings in question are several apartment blocks consisting of approximately 325 flats. 12 civic buildings are supplied through district heating, as are 4 centrals for street heating serving 12 000 m2 of streets and sidewalks, and a soccer field.

Emissions Cuts

In total, district heating provided 19 GWh of energy to buildings and plants in Porsgrunn in 2007, and 4,9 GWh to civic buildings.

Comprehensive emission reduction data have not been collected. However, given the emissions from production of a similar amount of energy using oil boilers, cuts resulting from district heating in 2007 would amount to:

  • 6000 tons of CO2
  • 10 tons of SO2
  • 6 tons of NOx

Reductions from civic buildings make up approximately 25 per cent.
