Hammarby Sjöstadsverket in Stockholm, Sweden, was built as part of the Hammarby Sjöstad initiative, with the aim of halving environmental impact by demonstrating new technology and innovative solutions. The facility is now continuing to serve as a development centre for new water treatment technology.
A sewage treatment plant was built as part of the Hammarby Sjöstad project to test new treatment processes and technology. The Royal Institute of Technology and the Swedish Environmental Research Institute (IVL) took over Sjöstadsverket in 2007 to turn it into a centre for innovative municipal water treatment. It will contribute to demonstrating Swedish water and environmental knowhow through research. The plant will strengthen development in the industry and improve the prospects for Swedish exports in water and environmental technology. Sjöstadsverket is a very successful example of how innovative investments can lead to great progress which in the longer will benefit the whole of society. Positive effects on environment and economy • Improved prospects of raising biogas production and reducing phosphorus emissions biologically by completely separating wastewater from households from surface and drain water. • Lower levels of heavy metals in the sludge, since surface water is treated separately. This improves the prospects of returning the sludge to the ecocycle. • The plant recycles nitrogen as effectively as urine separation in the home. • The project enabled smaller and innovative companies to test innovative solutions.
