  5. 4. A System Perspective on District Heating and Waste Incineration

    Författare :Kristina Holmgren; Björn Karlsson; Anna Björklund; Linköpings universitet; []
    Nyckelord :Energy recovery; District heating; Waste incineration; Waste management; Environmental; Material recovery; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Energy recovery by waste incineration has a double function as waste treatment method and supplier of electricity and/or heat, thereby linking the systems of energy and waste management. Both systems are undergoing great changes, mainly due to new regulations. LÄS MER
