    The heating and cooling system of the hospital in Kristianstad uses energy from an aquifer in order to heat the hospital in winter and cool it in summer. This is a unique clean energy solution that uses “free energy” in a creative way. The solution was developed by Region Skåne in cooperation with the company Malmberg Water.

    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.

    Developer and supplier of high-tech systems for cost efficient pre-treatment of biomass for use in heat and power generation, conversion to liquid fuels and production of green chemicals. Based on over ten years of research, BioEndev has developed an innovative torrefaction technology for production of black pellets. With over 10 patents we have a unique technology with high process control and availability. Black pellets resembles fossile coal in many ways but is renewable and carbon neutral. Black pellets are hydrophobic and has up to 50% higher energy density compared to white pellets.

    The municipalty of Skellefteå collect waste from homes and workplaces and produces there own biogasfuell for use in the municipality cars and in the public buses. The Biogas plant turns organic waste into biogas. Food bio waste from homes and workplaces is selected and placed in the brown waste container so that it can be taken to the biogas plant. The fuel that comes from this plant is used in the municipality cars and in the public buses, but it can also be bought by anyone whose car can take such fuel.

    In a unique project, Fortum provides Nynas AB refinery in Nynäshamn with process steam, coming from the biofuel-powered cogeneration plant. In return, Fortum is given access to the surplus heat from the refinery, which they will use to heat Nynäshamn’s municipality. This project will result in reduced emissions of carbon dioxide, with nearly 100 000 t / year.

    The district heating plant in Bålsta supplies Håbo municipality with environmentally-friendly heat and hot water. The plant consists of three boilers: a wood chip boiler, a pellet boiler and an oil-fired boiler, which together represent 80% of the plants total energy production. The remaining 20% are taken from a adjucent gypsum factory, whose waste heat is led to the boiler through pipes.

    At Campus Lindholmen, low-speed electric vehicles combine with specially designed trucks to collect sorted waste and distribute goods to a variety of recipients. The result is an 80–90 percent reduction in heavy-vehicle traffic. Campus Lindholmen in Gothenburg covers an area of less than 10 hectares (one-tenth of a square kilometre) but is a vital hub for developing sustainable waste collection and goods distribution and reducing heavy-vehicle traffic.

    The EU’s largest smart energy cities project, CELSIUS, has taken a leading role in demonstrating and promoting smart district heating and cooling solutions across Europe. More than 60 cities have now joined the project, coordinated by Sweden’s largest municipal energy company Göteborg Energi and the city.

    To improve accessibility in the city centre, a joint goods reception for smaller deliveries to downtown shops has been established.

    The city, property owners, transport companies and stores have collaborated to simplify regulations, establish walking speed areas and intensify checks. As a result, it is remarkably easier to distribute goods in the city while traffic intensity, noise and emissions have decreased. The participant response has been consistently positive and the model has attracted interest from other cities in Sweden and internationally.

    Clean public transport initiative

    The Clean Vehicles Poject started in the mid 90’s, originally to acquire environmentally friendly cars for the municipality. This led to the development of an infrastructure for the supply of clean vehicles and bio fuels. Since then, a considerable number of cars have been bought, tested and evaluated and the supply of clean vehicles and bio fuels has increased successively.

    Objective:

    Two sewage treatment works in Stockholm are producing biogas from sewage sludge. After having purified the gas, it can be used for both heating and vehicle fuel and in addition creates no net emissions of carbon dioxide. 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.

    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.
