  • Aquifer Heating and Cooling

    Type: 
    Product
    Objective:
    Technology:

    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.

  • Bio-heat gives steam to Nynäs refinery

    Type: 
    Product
    Objective:

    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.

  • Bålsta extracts waste heat

    Type: 
    Product
    Objective:
    Technology:

    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.

  • Cleaner air in Stockholm with sewage sludge

    Type: 
    Product
    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.

  • Dåva CHP

    Type: 
    Product
    Objective:
    Technology:

    Dåva CHP is one of the world's most energy efficient and environmentally friendly plants with waste as its main fuel. Here we produce district heating and electricity from sorted waste and residues from the forest industry.

  • E.ON. CFB Waste Incineration Plant

    Type: 
    Product
    Objective:
    Technology:

    Händelöverket is today owned by E.ON Värme AB. The first boiler was commissioned in 1982 and the site has since been extended and refurbished many times in order to always exhibit the latest environmental performance, the latest boiler was commissioned in 2011. Händelöverket is one of Sweden’s biggest and most modern power plants and it supplies Norrköping and Söderköping with heat and power and it also supplies process steam to Agroetanol for the production of ethanol. Händelöverket is an efficient system that utilizes 90% of the fuel’s energy. The fuel consists of 95% waste and biomass.

  • Eriksberg – From shipyard to sustainable housing

    Type: 
    Product
    Objective:

    Derelict industrial premises from the era of shipyards have been transformed into an exciting mix of modern housing and renovated dockside buildings.

    The reconstruction of Eriksberg was made with the environment in focus. One interesting feature is the underground waste collection system. Eriksberg is one of the first areas in the world using several fractions. It was started already in 1993 and is still expanding. When Eriksberg is complete the automated waste collections system will handle waste (food-, paper- and residual waste) for over 5000 apartments.

  • Food waste becomes biogas

    Type: 
    Product
    Objective:
    Technology:

    A small recycling centre in Huddinge municipality produces biogas using organic waste, which is unique in the Stockholm region. Despite the fact that only a few tons of biogas is produced every year, the plant brings important knowledge for future projects.

  • Gasendal – A world class biogas plant

    Type: 
    Product
    Objective:

    When opened in spring 2007, the Gasendal plant, was the largest biogas upgrading facility in the world.

    The plant receives biogas from Gryaab, a local wastewater treatment plant, and upgrades it to natural gas quality. The gas, which is injected into the natural gas grid, is used primarily as vehicle fuel in accordance with the green gas principle, in a way similar to the trade in green electricity. By replacing petrol with biogas in vehicles, carbon dioxide emissions is cut by up to 15,000 tons per year.

  • Gärstad waste-to-energy plant

    Type: 
    Product
    Objective:

    Thermal treatment of waste plant in Linkoping including the opportunity to discuss with representatives of the technical staff

    The participants will be given a full tour of one of the waste-to-energy plants in Linköping, the new Gärstad facility. The plant has an annual capacity to treat 195.000 tons of municipal and industrial waste. The energy output is 19MWe and 68MWth. The plant uses both dry and wet flue-gas cleaning technology. The visit is concluded in the control room where operations staff are present and willing to answer questions.

  • Landfill gas is being extracted in Bro

    Type: 
    Product
    Objective:
    Technology:

    The district heat plant in Bro produces environmentally friendly power. About ¾ of the installation's total heat production comes from landfill gas from Ragnsell landfill in Högbytorp. The remaining energy is produced by burning vegetable oil.

  • Lantmännen Agroetanol - Ethanol factory

    Type: 
    Product
    Objective:
    Technology:

    Ethanol can be produced from most raw ingredients that contain sugar or starch, which can in turn be broken down to sugar. In the Norrköping factory wheat, rye and barley are used as raw ingredients. Around 550,000 tonnes of grain are required to produce 210,000 m3 of ethanol. With a yield of 5.5 tonnes per hectare for wheat/triticale in Central Sweden, the factory's capacity is equivalent to a plantation of 100,000 hectares.

  • New combined heat and power plant in Solna

    Type: 
    Product
    Objective:
    Technology:

    The energy company Norrenergi has been commissioned to build a biofuel-fired district heat plant in northern Kymlinge. The installation will secure the supply of electricity and heat in growing areas within the municipalities of Solna and Sundbyberg. Furthermore, thanks to the plant, the municipalities can count with reduced emissions of carbon dioxide by 15 %, which is in line with the Parliament’s fixed objective for reduced emissions.
