  1. 6. Assessing the sustainability of bioethanol production in different development contexts: A systems approach

    Författare :Dilip Khatiwada; Semida Silveira; Faaij André; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioenergy and biofuel; bioethanol industry; development trend; sustainability assessment; climate change mitigation; energy security; life cycle assessment; systems optimisation; bioenergi och biobränsle; bioetanolindustri; utvecklingstrender; hållbarhetsbedömning; motverka klimatförändringar; energisäkerhet; livscykelanalys; systemoptimering; SRA - Energy; SRA - Energi;

    Sammanfattning : The continuous depletion of fossil fuel reserves, the global agenda on climate change and threats to energy security have led to increased global interest in the exploration, production and utilisation of bioenergy and biofuels. Access to modern bioenergy carriers derived from the efficient conversion of locally available biomass resources is indispensable for economic growth, rural development and sustainable development in developing countries.

  3. 7. Decision support for the implementation of low-carbon measures in the building sector

    Författare :Nicolas Francart; Tove Malmqvist; Paula Femenias; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building; sustainability; environmental performance assessment; life cycle assessment; decision making; byggnad; hållbarhet; miljöprestandabedömning; livscykelanalys; beslutsstöd; Strategier för hållbar utveckling; Strategies for sustainable development;

    Sammanfattning : The building sector is responsible for about a fifth to a third of global greenhouse gas (GHG) emissions. Therefore, a successful mitigation of GHG emissions over the entire life cycle of buildings is particularly important to achieve climate targets such as the Paris Agreement. LÄS MER

  4. 8. Performance Assessment of Wastewater Treatment Plants : Multi-Objective Analysis Using Plant-Wide Models

    Författare :MAGNUS ARNELL; Ulf Jeppsson; Bengt Carlsson; Hans Bertil Wittgren; Diego Rosso; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; benchmarking; BSM; samrötning; energieffektivitet; växthusgasutsläpp; livscykelanalys; matematisk modellering; avloppsvattenrening; benchmarking; BSM; codigestion; energy efficiency; greenhouse gases; life cycle assessment; mathematical modelling; wastewater treatment; benchmarking;

    Sammanfattning : As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. LÄS MER

  5. 9. Organising matters for the environment: Environmental studies of housing management and buildings

    Författare :Birgit Brunklaus; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; life cycle assessment LCA ; Livscykelanalys; environmental management systems EMS ; field studies; housing management; environmental assessment; buildings; passive house technology; action nets; organisation theory; Miljöteknik; environmental management; Miljövetenskap; Tvärvetenskap; Organisationsforskning;

    Sammanfattning : Buildings give rise to several environmental problems over the whole life cycle. To reduce these, technical measures with focus on energy are commonly used. However, environmental problems are more than energy and cannot be solved with technical measures alone. LÄS MER

  7. 10. 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
