Energy from waste
In addition both emissions of greenhouse gasses and other environmental impacts are reduced considerably as compared to depositing the waste. Modern purifying technology is utilised resulting in low emissions to the air.
In 2008 Hafslund completed a new energy recovery plant in Fredrikstad (BioEl), which was officially opened on World Environment Day on 5 June.
This is a modern fuel-flexible plant with a high environmental standard. The plant extracts energy from approx. 45-66 000 tonnes of waste based fuel per year. Annual supply is approx 110 GWh industrial steam, district heating and electricity.
In line with its focus on renewable energy, Hafslund signed an agreement with Borregaard to build, own and operate an energy recovery plant, fuelled by waste from Borregaard’s industrial site in Sarpsborg. The facility will supply steam to replace the heavy oil used in Borregaard’s industrial processes. The facility opened 1 March 2010.
This is a modern fuel-flexible plant with a high environmental standard. The plants will significantly reduce the use of heavy oils and thereby the release of fossile CO2. The impact study shows that the total air quality in Sarpsborg will be improved.
The plant, which will provide industrial steam to Borregaard, will each year burn approx. 80 000 tons of waste based fuel. The annual energy production will be approx. 230 GWh.
From waste to heat
A significant share of Oslo’s district heating comes from waste incineration, biofuel facilities and heat pumps that extract heat from sewage. These are resources that would otherwise be lost or considered waste. Today’s investment in district heating saves Oslo from annual GHG emissions corresponding to more than 100,000 cars each driving 15,000 km. The goal is to replace all fossil fuels for peak loads by 2016. This will make a substantial contribution to Oslo’s environment and cut carbon emissions.
