The Väla Gård office building in Helsingborg, southern Sweden, is Skanska’s greenest office building to date. The building achieved LEED Platinum and became Sweden’s first Deep Green building by achieving net zero energy, and by being constructed with zero hazardous materials and with zero waste sent to landfill.
Within Umeå municipality there are a total of 19 wastewater treatment plants. The largest, Umeå Wastewater Treatment Plant, takes care of wastewater from households and various businesses in Umeå and surrounding villages. Every year, it receives about 13 million cubic meters of waste water, containing about 3000 tons of organic material and about 80 tonnes of phosphorus. The process of cleaning water demands a lot of energy, but the plant also produce biogas which gives 23 000 kWh per day.
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.
Both the natural values and economic values have increased in Nykvarn since the municipality restored the mercury-contaminated lake Turingen, The today ineadible fish will in a relatively near future be eadible again.
The major soil remediation projects carried out in Stockholm during the last decade were in many ways unique and resulted in new experiences. Four areas were remediated from contamination, partly with new technology and help from entrepreneurs, who have never worked in Sweden before.
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.
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.
In Malmö with its 300,000 inhabitants household waste is collected by the waste management company VA Syd. In the residential area of Augustenborg all fractions of waste are sorted in waste management houses close to residential buildings. In this area, substantial efforts have been made to simplify the sorting of waste and to inform residents about the need to sort waste and thereby participate in the pilot program.
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.
The largest and northern most full-scale system for wastewater irrigation of Salix plantations in Sweden. The local community in Hedemora has long experience in producing biofuel from Salix plantations. The cooperation between Hedemora Energi AB and local farmers has resulted in irrigation of 75 acres of Salix Plantations. The local farmers in the project are guaranteed to sell their biofuel to the local municipal heating plant. As a result the project is contributing to the local production and consumption.
Vertical Wind has developed a new and exciting wind power technology based on a vertical axis wind turbine with a cable-wound direct driven generator. The turbine does not need a pitch or a yawing mechanism and the direct driven generator eliminates the need of a gearbox. The robust and simple technology with few moving and sensitive parts compared to conventional wind turbines, gives a higher availability and reliability as well as lower cost for maintenance. Furthermore, this type of wind turbine is quieter than its horizontal counterpart.
Törnebybäcken, a stream which drains most of the Kalmar countryside just west of Kalmar, is one of the municipality's most nutrient-loaded water bodies. Kalmar airport contributes to the supply of mainly nitrogen that is used to keep the runways unfrozen. Through a unique partnership between CAA and Kalmar municipality, a large proportion of mainly nitrogen, but also phosphorus that would otherwise be added to the West Lake (a bay of the Baltic Sea), are deleted in the landscaped wetland park Kalmar Dämme.
Wind power is an endless and renewable source of energy that has been used for thousands of years. It plays an important role in Umeå Energis investment in renewable energy and is in line with the company’s aim to be completely carbon neutral by 2018. In total, the municipality owned company Umeå Energi owns ten wind turbines, which provide significant climate benefits. These turbines are situated in the towns of Hörnefors, Holmsund and Robertsfors.
The Älvsbacka Bridge in Skellefteå is one of many pedestrian bridges constructed by Martinsons since the end of the 1980s. The enviromental benefits frome construction in wood is just one of many. Wooden pedestrian bridges have many advantages over other bridge types: High level of prefabrication - Fast assembly times - Minimal inconvenience to traffic with bridge spanning a road - Low costs for transport and laying the foundation - Documented quality and service life - Competitive prices
World's first eco-labeled heating! As the first company in the world Falun Energy & Water now delivers heating, cooling and electricity with Environmental Certification. The label sets very high standards for the goods accepted and is often called "the world's toughest environmental label".
Solar energy is becoming an increasingly realistic alternative in the Gothenburg region. The conditions for solar energy are roughly similar to those in Germany, where full sunshine generates solar energy equivalent to 20 nuclear power stations.
