  1. 16. Towards empirically grounded guidance for resource efficiency: Applying, developing and synthesising environmental assessments

    Författare :Daniel Böckin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Circular Business Models; guidelines; business models; synthesis; Life Cycle Assessment; decoupling; resource efficiency; 3D-printing; Circular Economy; waste hierarchy;

    Sammanfattning : Numerous solutions have been proposed to mitigate environmental damage, including resource efficiency and the vision of circular economy. Suggested solutions are often formulated as guidelines and heuristics like in the EU waste hierarchy, so-called R-hierarchies for resource efficiency and various guidelines for circular business models.

  3. 17. Environmental assessment of municipal solid waste incinerator bottom ash in road constructions

    Författare :Susanna Olsson; Jon Petter Gustafsson; Dan Berggren; Erik Kärrman; Bo Bergbäck; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bottom ash; environmental impact; LCA; waste management; leaching; copper; dissolved organic carbon; Environmental chemistry; Miljökemi;

    Sammanfattning : There are several incentives for using bottom ash from municipal solid waste incineration (MSWI bottom ash) as a construction material, such as for road construction. These incentives include decreased disposal of material on landfills and a reduced amount of raw material extracted for road building purposes. LÄS MER

  4. 18. Dioxin emissions from small-scale combustion of bio-fuel and household waste

    Författare :Björn Hedman; Stellan Marklund; Calle Nilsson; Brian Gullett; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Source-sorted waste; Household waste; Textile; Biofuel; Firewood; Pellets; Combustion; Wood boiler; Pellet boiler; Backyard burning; Garden waste; PCDD F; dioxin; PCB; Emission factor; Källsorterat avfall; Hushållsavfall; Textil; Biobränsle; Ved; Pellets; Förbränning; Vedpanna; Pelletpanna; Trädgårdsavfall; PCDD F; dioxin; PCB; Emissionsfaktor; Environmental chemistry; Miljökemi;

    Sammanfattning : Denna avhandling behandlar rökgasutsläpp av persistenta organiska föroreningar, framförallt dioxiner, vid förbränning av fasta biobränslen och torrt hushållsavfall i relativt små anläggningar (5-600 kW) utan avancerad rökgasreningsteknik.Samförbränning av avfall och biobränsle i effektiva mindre biobränslepannor testades som en alternativ strategi till den vanligen förekommande storskaliga hanteringen och förbränningen fast hushållsavfall.

  5. 19. Exploring the circular economy of urban organic waste in sub-Saharan Africa: opportunities and challenges

    Författare :Daniel Ddiba; Göran Finnveden; Elisabeth Ekener; Sarah Dickin; Cecilia Lalander; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biowaste; governance capacity; resource recovery; sub-Saharan Africa; sustainable sanitation; sustainable urban development; circular economy; Strategier för hållbar utveckling; Strategies for sustainable development;

    Sammanfattning : Globally, there is increasing awareness of the importance of applying circular economy principles to the management of organic waste streams through resource recovery. In the urban areas of sub-Saharan Africa which are going to host a significant part of population growth over the next three decades, this is especially relevant. LÄS MER

  7. 20. Renewable Energy and Nutrient Valorization from Anaerobic Digestion : Resource-Efficient Solutions

    Författare :Sandra Carlos-Pinedo; Zhao Wang; Ola Eriksson; Shveta Soam; Henrik Wenzel; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid-state anaerobic digestion; methane yield; digestate; systems analysis; modelling; life cycle assessment; Torrötning; metanutbyte; biogödsel; systemanalys; modellering; livscykelanalys;

    Sammanfattning : This thesis presents a comprehensive analysis aimed at understanding process performance, methane yield, and key influencing factors within the context of solid-state anaerobic digestion (SS-AD). SS-AD is used to treat organic material with high solids content, which can be challenging to address by alternative methods. LÄS MER
