  1. 1. System studies of biogas production : comparisons and performance

    Författare :Emma Lindkvist; Magnus Karlsson; Mats Söderström; Maria Johansson; Ola Norrman Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Biogas has the potential to be part of the transition towards a more sustainable energy system. Biogas is a renewable energy source and can play an important role in modern waste management systems. Biogas production can also help recirculate nutrients back to farmland. LÄS MER

  3. 2. Regional Energy Systems with Retrofitted Combined Heat and Power (CHP) Plants

    Författare :Song Han; Yan Jinyue; Thorin Eva; Deng Shiming; Mälardalens högskola; []
    Nyckelord :Combined heat and power; Waste-to-Energy WtE ; Regional energy system; Greenhouse gases GHG ; Retrofitting; Optimization; Kraftvärme; Avfall-till-Energi; Regionala Energisystem; Växthusgaser; Uppgradering; Optimering.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Fossil fuel depletion, economic development, urban expansion and climate change present tough challenges to municipal- and regional-scale energy systems. Regional energy system planning, including waste treatment, renewable energy supply, energy efficiency, and climate change, are considered essential to meet these challenges and move toward a sustainable society.

  4. 3. Determination of Volatile Sulfur Compounds in Air and other Gas Matrices : Development and Applications of Solid-Phase Microextraction

    Författare :Fräs Annika Andersson; Bo Svensson; Josep M. Bayona; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Volatile sulphur compounds (VSCs) are frequently emitted during bioindustrial activities, such as production of biogas, sewage treatment, landfilling, pulpmilling, and the slaughtering of animals and meat processing. VSCs are reactive and malodorous, and they can also be detrimental to human health, therefore it is of great interest to be able to analyze these compounds. LÄS MER

  5. 4. Improvement of Wastewater Sludge Digestion

    Författare :Michael Recktenwald; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

    Sammanfattning : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. LÄS MER

  7. 5. Intensification of the biogas process by improved process monitoring and biomass retention

    Författare :Lovisa Björnsson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOD; hydrogen; on-line; monitoring; biofilm; anaerobic digestion; biogas; Biotechnology; Bioteknik;

    Sammanfattning : The utilisation of energy in the form of biogas is one of the environmentally sound alternatives available using renewable energy sources. Biogas is formed by anaerobic degradation of organic material, the main consistuent being energy-rich methane. LÄS MER
