Sjölunda Wastewater Treatment Plant, Malmö At the Sjölunda plant in Malmö wastewater from 550,000 inhabitants is treated. The plant was built in 1963. Recently expansion of biological treatment has reduced the use of precipitation chemicals to meet the Swedish requirements and the plant has at the same time reached emission requirements of organic compounds, phosphorous, and nitrogen. The sludge produced is used at the plant’s own production unit for biogas.
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.
An international biorefinery hub. SP Processum has during a number of years purposefully built up a set of pilot equipment aimed at biorefinery projects. The equipment consists of pilots for thermochemical pre-treatment, biochemical processes, thermochemical syntheses as well as pilots for separations. A broad spectrum of biomasses, like forest raw materials of all kinds as well as industrial residual streams and waste materials, can in pilot scale be converted to e.g. materials, proteins, bioenergy and chemicals.
When the new football field at Katrineholms Sports center was constructed, heating coils underneath the pitch were installed, which makes its playable even in winter. The heat is collected from an underground energy storage, where waste heat from the artificially frozen bandy court’s compressors is stored.
In Örnsköldsvik we prioritize sustainable travels and the goal is highlight and use sustainable travel habits in Örnsköldsvik, for example to choose active transportation such as walking and cycling. It may also be to commute by carpooling, or go by public transport such as train or bus. Or best of all not to travel at all. Instead we use Webb- or telephone meetings when it is possible. The municipality's new Bicycle Plan and parking strategy shows the long-term jobs performed in sustainable travel.
Sysav (South Scania Waste Company) and Sysav Industri AB receives, recycles and treats waste from households and businesses in southern Skåne. The companies are owned by 14 municipalities with a joint population of around 700,000, and have approximately 6,000 companies as customers.
Säbyverket produces heat by firing bio fuel and wood powder. Wood powder is a by-product from forestry industry and the incineration of this product entails no additional input of carbon dioxide to the atmosphere.
In 1996 the decision was taken to create an eco-city from the 1950’s housing estate and 1960’s industrial area. This provides an excellent example of a successful sustainable makeover of an urban district. The make-over focused on efficient water systems, green roofs, and solar energy. The water systems include surface rainwater runoff systems, canals, and ponds.
This “city within a city” has its own systems for managing its energy supply and waste treatment. Car traffic in the area has been minimized as an environmentally friendly approach to urban planning and mobility.
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.
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.
