  1. 1. Leveraging green hydrogen to decarbonise the aviation industry : A case study on electrofuels in Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jakob Bergene; Jonathan Bruchhausen; [2023]
    Nyckelord :Electrofuel; e-fuel; electrokerosene; e-kerosene; SAF; sustainable aviation fuel; sustainable aviation; complementarity formation mechanisms; technology value chains; TVC; Techno-economic analysis; TEA; Elektrobränsle; e-bränsle; elektrofotogen; e-fotogen; SAF; sustainable aviation fuel; sustainable aviation; komplementära formationsmekanismer; technology value chains; TVC; Techno-economic analysis; TEA;

    Sammanfattning : For the EU to reach its 2050 climate targets the aviation industry that is highly dependent on fossil fuels needs to drastically reduce its emissions. In the decarbonisation of the aviation industry drop-in sustainable aviation fuels (SAFs) have been identified as a promising solution to abate the industry’s emissions. LÄS MER

  3. 2. Food waste in bakeries- quantities, causes and treatment

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Maryna Iakovlieva; [2021]
    Nyckelord :bakery waste; bakeries; causes of losses; producers; Swedish bread industry; take-back agreement;

    Sammanfattning : Bread waste represents a considerable part of food waste in Sweden, and in general, food waste can have a significant impact on the environment. This study assesses the quantity of food waste in bakeries and identifies the main causes of waste during the production of baked products. A sample was taken from the total number of bakeries in Sweden. LÄS MER

  4. 3. Evaluating Sugar Signaling during Xylose Oxidation in Saccharomyces cerevisiae

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Viktor Persson; [2020]
    Nyckelord :Saccharomyces cerevisiae; yeast; xylose oxidation; sugar signaling; biosensor; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Sammanfattning : The sugar signaling state of cells oxidizing xylose was investigated through the chromosomal integration of the Weimberg pathway into previously established biosensor strains capable of monitoring the Snf3p/Rgt2p, SNF1/Mig1p, and cAMP/PKA pathways through the expression of HXT1, SUC2, and TPS1, respectively. Ultimately, two new strains were successfully developed containing both the Weimberg pathway and a biosensor for either HXT1 (TMB CB 112) or TPS1 (TMB CB 117). LÄS MER

  5. 4. Reconstruction of Genome-Scale Metabolic Models with Concomitant Constraint-Based Modelling for Flux Prediction – a Case Study of Syngas Consuming Hydrogenophaga pseudoflava

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Cristopher Ollagnier Widén; [2020]
    Nyckelord :Applied Microbiology; flux-balance analysis FBA ; genome-scale metabolic model GEM ; Hydrogenophaga pseudoflava DSM 1084; KEGG; metabolic engineering; metabolic modelling; metabolic network reconstruction; RAVEN; syngas; systems biology; Technology and Engineering;

    Sammanfattning : Metabolic modelling coupled with flux-balance analysis (FBA) has become a popular tool in systems biology for quantitative predictions of metabolic processes in silico, and as an aid in metabolic engineering. Drawing upon gene-protein-reaction associations deducible from information on the genome-level, so-called genome-scale metabolic models (GEMs) are unequalled in their scope as they attempt to encapsulate the entire reactome of a species or cell type.

  7. 5. A sustainability assessment for public buses : A multi-criteria approach

    Master-uppsats, KTH/Hållbarhet och miljöteknik

    Författare :Eamon Magorrian; [2018]
    Nyckelord :MCA; Transport; Sustainability; Efficiency; Cost; Bus; HVO; FAME; Bioethanol; Biogas; BEV; Weighting;

    Sammanfattning : Many city planners, regional authorities and transport providers are tasked with the challenging job of selecting which type of public buses are suited to their location and priorities. The challenges of which are multidimensional in nature due to different policies to adhere to as well as economic, environmental and technical tradeoffs between options. LÄS MER
