  1. 16. Forest industry sludge as a resource for energy recovery

    Författare :Alina Hagelqvist; Ola Holby; Karin Granström; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Forest industries produce large amounts of carbon rich sludges as by-products in their processes. Presently sludge is treated as a poor quality biofuel for co-incineration, some mills treat it solely as a disposal problem. This thesis provides an introduction to production, composition and disposal issues of sludge. LÄS MER

  3. 17. Developing strategies for improved economic performance and reduced climate impact of landfill mining in Europe

    Författare :John Laurence Esguerra; Joakim Krook; Niclas Svensson; Steven Van Passel; Anders Damgaard; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; landfill management; resource recovery; sustainability assessment; emerging concept;

    Sammanfattning : Landfill mining refers to the re-circulation of resources from the previously deposited wastes. It is an alternative approach for managing landfills that integrates resource recovery with site remediation. LÄS MER

  4. 18. Valorisation of heterogeneous industrial residues towards a circular economy : A systems-oriented investigation on how to facilitate shredder fines valorisation in the Swedish context

    Författare :Tharaka Gunaratne; Joakim Krook; Hans Andersson; Jouni Korhonen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular economy; Systems analysis; Valorisation; Resource recovery;

    Sammanfattning : In the context of circular economy in the European region the role of the recycling industry has become ever important. Shredder fines (or fines) is a heterogeneous fine-granular production residue of the shredding industry, and is currently disposed of. Shredder fines presents a disposal problem and incurs handling costs to the shredding industry. LÄS MER

  5. 19. Small Sanitation Systems – Treatment Efficiency, Sustainability and Implementation

    Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Günther Langergraber; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable sanitation; sand filter; phosphorus filter; package plant; cold climate; treatment process; system analysis; sustainability indicators; decentralization; centralization; historical development; on-site; resource recovery; source separation; source-separating systems; blackwater; urine; greywater; hållbarthetsanalys; små avlopp system; enskilda avlopp; markbädd; minireningsverk; kallt klimat; systemanalys; fosforfälla; fosforfilter; indikator; urin sortering; svartvatten; toalettvatten; gråvatten; BDT; VA-teknik; Urban Water Engineering;

    Sammanfattning : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. LÄS MER

  7. 20. 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
