Waste incineration at Högdalenverket
Högdalenverket, which is one of Europe’s most modern installations for energy extracted from waste, produces electricity and heat from Stockholm’s combustible household waste and industry waste. Högdalenverket is an important component in the district heating network of southern Stockholm.
Cleaner air in Stockholm with sewage sludge
Two sewage treatment works in Stockholm are producing biogas from sewage sludge. After having purified the gas, it can be used for both heating and vehicle fuel and in addition creates no net emissions of carbon dioxide. Consequently, the treatment works have reduced their amount of emissions and become energy suppliers. Therefore, sewage sludge is no longer an environmental problem, but an important energy resource.
The Hammarby Sjöstad Ecocycle
The goal for Hammarby Sjöstad in Stockholm, Sweden, was to halve the overall environmental impact compared with if the area had been built in the early 1990s. The goal was not fully attained. But thanks to the ambitious target and integrated planning, this lakeside town has set an international example.
Environmental investments in Vällingby Centrum
Svenska Bostäder have invested over three million Swedish kronor in an installation for geothermal energy and a recycling central. Thanks to the investment, Vällingby Centrum produces nowadays its own energy, which provides the shopping centre with 60 % of its need for heating and 90 % of its need for cooling.
Underground waste management
Thanks to a stationary pneumatic refuse collection system, the garbage doesn’t need to be collected by trucks anymore. Instead, the garbage is transported by air through pipes, where it is compacted in sealed containers. Using a vacuum system instead of an old-fashioned refuse room or waste container does away with problems with unpleasant odours, and nobody needs to come into contact with waste bags or containers.
