Consequently, the treatment works have reduced their amount of emissions and become energy suppliers. Therefore, sewage sludge is no longer an environmental problem, but an important energy resource.
Climate Friendly Childbirths
Nitrous oxide is used during 80 per cent of childbirths. This gas is a green-house gas 310 times stronger than carbon-dioxide and one kilogram that is emitted into the atmosphere is equivalent to 1500 kilometres of driving a car. Region Skåne, the regional health care management organization of southern Sweden has installed equipment from the company Nordic Gas Cleaning for separating the nitrous oxide into oxygen and nitrogen at all of its five hospitals with birth clinics. This has not only reduced emissions by 99 per cent. It has also improved the work environment for midwives, who previously felt tired and nauseous after inhaling substantial amounts of air contaminated by nitrous oxide. Now both midwives and birth-giving mothers feel better due to this improvement.

The Kristianstad recycling park is one of the best examples of the Swedish system of waste management. The material and energy recycling rate is currently 97% and the goal is to reach 100% in the near future. By increasing the volume of material recycled, the amount of material deposited has been decreased by 40,000 tons. The facility was opened in 2001 and it then replaced a previous landfill site.
Reduction of Hospital Waste
The central hospital in Kristianstad has succeeded to substantially reduce its volumes of waste that is incinerated and has instead started to recycle increasing volumes of paper and plastics. One clinic that had a high rate of recycling at the beginning of the project increased the volume of recycled waste by 300 per cent. The project involved both increasing the volumes of waste that were sorted at the clinics and implementing a system for sorting sacks of waste for recycling and incineration in the hospital’s waste management system. The system uses sacks of paper and plastic of different colours to identify different fractions of waste. The more valuable recyclable waste is now recovered, which saves substantial amounts of money for the hospital.
Restoration of overgrown meadows
At Svartsjöviken in Ekerö municipality, overgrown meadows have been restored. The grounds, which had a low sustainability, were restored with newly developed aphibious vehicles, light band wagons and stump cutting equipment.

The sludge produced is used at the plant’s own production unit for biogas. After a final flotation step for the removal of suspended solids the treated water is released into the Baltic Sea 3 kilometres off the coast.
Sjöstadsverket tests new treatment methods
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.
Opposite the City Hall, 3 new building are under construction: a congress hall, a hotel and an office building. The project, known as Stockholm Water Front commenced in 2005, when the City of Stockholm decided to build a new conference centre with a hotel facility. But an office building was also built. in order to finance its realization. Stockholm Water Front aims to achieve environmental excellence. There are three installations, which make this possible:
<em>Glass Facades are giant solar collectors</em>
The large glass facade of the Congress Hall is perfectly located in the southern direction and acts as a giant solar collector. Already in the beginning of March, it is possible to extract 1 MW of energy. The façade has double layers of glass with air between them, which is heated by the sun. The hot air is converted to hot water and distributed to other buildings, for heating domestic water.
<em>Energy in balance</em>
Stockholm Water Front consists of three buildings with totally different energy profiles. The office building does not use much energy during evenings and nights and the hotel has its highest energy consumption during mornings and evenings. This imbalance is used whereby energy is transferred between the buildings according to the demand. In order to produce cooling, Stockholm Water Front uses a method, called phase transformation, which means that the cooling is stored in ice during the night. Plain water is extremely effective in storing cold. In addition one will also use cold water from the nearby Klara Lake.
