The Ecological City of Tomorrow in the Western Harbour, Malmö
Western Harbour, previously a run-down shipyard and industry area of 187 hectares, is today a vivid “city within a city” with a university, ~10,000 inhabitants and more than 16,000 people working (2016). The area 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.
Artificial wetlands in Trosa
Since 2003 the waste water from the town of Trosa (about 4500 citizens) has been treated in artificial wetlands, after the basic treatment in the sewage plant. Thanks to the wetlands the Trosa river and the town bay have been spared from eutrophicating substances (plant nutrients) as well as contagious substances (pathogenes). Besides the value of purifying the water, the wetlands are a popular recreation area. The wetlands are used for education and many study visits are made here. Vagnhärad, the neighbouring town with about 4500 citizens, has a similar area of artificial wetlands since 2001.
