About the region

Smart City Sweden East consists of four counties: Stockholm, Uppsala, Södermanland and Sweden’s largest island: Gotland. The region offers a long tradition of cooperation between business and academia, which has contributed to a high level of innovation and a favorable business climate.

Building smart cities require the public sector to be integrated to a large extent, which can be seen in examples in districts such as Hammarby Sjöstad and Stockholm Royal Seaport, where there has been a high focus on climate, environment and energy issues.

A wide range of platforms and corporate networks promote innovation and development in the region. One successful example is the Urban ICT Arena in Kista in the north of Stockholm, one of the world’s leading business clusters for innovation in digitalisation.

Stockholm has one of the world’s largest and most complicated district heating systems with a large number of actors who together produce and distribute district heating & cooling and electricity from hundreds of production units to millions of people. The production has the world’s largest heat pump plant, innovative energy storage, and waste incineration to recover energy from residual products from society and forestry, which contributes to a well-functioning waste management system. Uppsala and Gotland also have well-developed district heating networks with a very small proportion of fossil fuels.

Water and wastewater treatment are key functions in a well-functioning city, a service that often goes unnoticed as long as it performs as planned. Uppland, Södermanland and Gotland all have different challenges with water quality and water supply that have been solved in different ways. In Uppsala, the regional capital of Uppland, water from the passing river Fyrisån is purified through a ridge due to groundwater scarcity. At Hammarby Sjöstadsverk in Stockholm, unique research is conducted on membrane technology for more efficient wastewater treatment, which will make Henriksdal’s wastewater treatment plant one of the largest in the world to use membrane technology. On Gotland, the testbed Storsudret is testing new solutions in drinking water purification.

Social sustainability is key in urban development projects and by initiating dialogue and involvement during construction and renovation processes, the likelihood of a successful project increases significantly. Smart City Sweden East offers examples of social sustainability, such as Fryshuset, an organization that works to support and include young people in the community.

Underground Storage of Cold Water

Underground Storage of Cold Water

A rock chamber of 50,000 cubic meter was created in central Stockholm in 2010 for the storage of cold water, with the aim to reduce the peak load on energy production. The plant has helped to reduce carbon dioxide emissions by approximately 30,000 tonnes per year.

Biogas Xpose: sustainable biogas production through innovative technologies

BIOGAS XPOSE demonstrates how a region with a high demand for biomethane (BM) can increase the production of BM as a renewable vehicle fuel in an economically and environmentally viable fashion by maximizing regional waste as the resource. The project is reducing the total emissions of carbon dioxide with 334 600 tonnes by sustainable production of BM that replaces fossil fuels in the transportation sector. The project ended in 2018.

Extended Producer Responsibility in Sweden: Towards better waste management

Extended Producer Responsibility in Sweden: Towards better waste management

Extended Producer responsibility (EPR) is a governmental policy and a Swedish law that aims to better waste management and collection. The Swedish system shifts the waste management cost or physical collection fully from local governments to producers. The policy applies to different goods such as packaging, newsprint, electronic products, batteries, tires, end-of-life vehicles, pharmaceutical waste, stray radioactive products and radioactive sources.

Artificial wetlands in Trosa

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.

Underground waste management

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.
