    Sammanfattning : Immense amounts of waste are generated daily by our society, and the management of these streams is a critical societal function. Part of this work is reusing and recycling materials with attractive properties, which is also an imperative step towards circular material flows. LÄS MER

  2. 2. Oulu Biovillage: Exploring Blue Bioeconomy Ecosystem Opportunities in Oulu, Finland

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Emeline Lex; [2019]
    Nyckelord :Bioeconomy; blue bioeconomy; circular economy; ecosystem; waste-to-resource systems; local; community; regenerative; fish; aquaculture; renewable energies; biogas; bioenergy; live-work; cradle-to-cradle; typologies; greenhouse; environment; business; Oulu; Finland; Arts and Architecture;

    Sammanfattning : By the year 2030, the world will need 50% more food, 45% more energy and 30% more water. This growth in demand will increase pressure on our natural resources. Ingenuitive and adaptive thinking will therefore be required in the ways we build our cities. LÄS MER

  3. 3. Correlations related to fuel usage patterns in rural Kenya : A comparison of local surveys to facilitate future local sustainable fuel actions.

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Sammanfattning : Human activities affect the climate. If the utilization of fossil and other hazardous fuel methods is eliminated, it would reduce the impact on climate change. LÄS MER

  4. 4. Avkokskomprimering till CBG-lager som avkokshantering på LBG-tankstationer

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Olle Levin; [2019]

    Sammanfattning : The number of fuel stations for liquefied biogas or liquefied natural gas (LBG or LNG, both composed of liquid methane) in Sweden will increase in the coming few years, from 6 stations to over 30 in total. While there still are very few LNG heavy-duty vehicles (HDV's) on Swedish roads, technical problems may arise at fuel stations due to low consumption. LÄS MER

  5. 5. Purification and refolding of a novel dipeptidyl peptidase III

    Kandidat-uppsats, Linköpings universitet/Kemi

    Författare :Lennie Jansson; [2019]
    Nyckelord :dipeptidyl peptidase III; DPP III; purification; refolding; protein; Arg-Arg-2NA;

    Sammanfattning : There is a continuous search for novel enzymes to complement the abilities of today’s commercially available enzyme and find tailor-fit alternatives to suit the diverse array of bio-based industries. One application could be to increase biogas yield by finding substrate degrading proteases that can be added to the anaerobic digestion process and survive degradation themselves. LÄS MER
