Arlanda Airport reduces its emissions

Arlanda Airport has managed to reduce its emissions of carbon dioxide with 50 %. A strong contributing factor to the reduced emissions has been the investment in geo energy, which is taken from an underground aquifer.

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.

Destruction plants for laughing gas at three hospi

In 2011 the laughing gas emmissions had decreased with 75% in Stockholmslänslandsting compared to the emmissions in 2002

Extensive renovation made a 70´ies building energy

The City block Pennfäktaren was once a energy-guzzling building from the 1970’ies, which has been rebuilt and become one of Stockholm’s most modern office buildings, with many examples of cleantech installations.

Käppala – an efficient water treatment plant

Käppalaverket is one of the world’s most efficient water treatment installations, with the entire northern Stockholm as a catchment area. Apart from the fact that the installation treats water for over 500 000 people, it also produces biogas, running 100 busses.

Laduvikens Waterparc

At Laduviken, 5 million Swedish kronor is invested in a water park, which will reduce the amount of pollutants entering the lake through storm water. The aim is, among other things, to reduce phosphorus by 25%.

Landfill gas is being extracted in Bro

The district heat plant in Bro produces environmentally friendly power. About ¾ of the installation’s total heat production comes from landfill gas from Ragnsell landfill in Högbytorp. The remaining energy is produced by burning vegetable oil.

New Strömkajen

In the autumn of 2009, the Ports Authority of Stockholm commenced the improvement and repair of Strömkajen, which is both a street and a quay on the southern shore of Blasieholmen Island in Stockholm.

The eco-smart Kungsbrohuset

In Kungsbrohuset, there are several innovative cleantech solutions. Among other things, Kungsbrohuset recovers the excess heat, generated by the commuters at the Stockholm Central Station. Water from Klara Lake is used for cooling the building.

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.

Vacuum system in Östermalmshallen

A vacuum system handles the waste in Östermalm’s food market hall. The waste is transported via pipelines by means of under pressure to a storage unit and later to a biogas installation. With this system, waste is no longer a problem, but a resource.

Waste seperation with the help of vacuum technology

In the district of Hagalund in Solna, trucks with a mobile vacuum technology, collect waste and newspapers. The system is not only easy for the residents, it also improves the waste collector’s work environment and reduces the operating costs.
