  1. 1. 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

  2. 2. Multi-criteria assessment of biomethane production from waste and residual feedstocks of Emilia-Romagna (Italy)

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Giovanni Zanaroli; [2019]
    Nyckelord :biomethane; nutrients recycling; anaerobic digestion; multi-criteria assessment; transport;

    Sammanfattning : Biomethane can be produced by anaerobic digestion of residues or wastes and it can be used as a renewable fuel for transport. It is associated with reduced GHG emissions, offsetting of fossil fuels and of mineral fertilizers, waste management and nutrient recycling in agriculture. LÄS MER

  3. 3. CO2 savings of selling food surplus in plastic trays compared to incineration and anaerobic digestion in Sweden. : With an application at KTH Royal Institute of Technology

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

    Författare :Viktoria Rodopoulou; [2019]
    Nyckelord :waste management; food surplus; energy savings; waste to energy technologies; life cycle assessment;

    Sammanfattning : Food waste has become a global environmental concern in recent years with food waste prevention being the optimal solution. In Sweden, initiatives to reduce food waste, focus on re-using methods like selling or donating food. The purpose of this study is to analyze the environmental savings, in terms of CO2 eq. LÄS MER

  4. 4. Opportunities for small-scale anaerobic digesters for hotels and restaurants in Kathmandu, Nepal

    Master-uppsats, KTH/Energiteknik

    Författare :Avinash Dhital; [2018]
    Nyckelord :anaerobic digestion; biogas; bio-waste; small-scale; cooking; fuel; hotels; restaurants; Nepal;

    Sammanfattning : About 83% of total energy consumed in Nepal comes directly from the solid fuels. The import of Liquified Petroleum Gas (LPG) is also growing at an exponential rate. LÄS MER

  5. 5. Impact on carbon emissions applying the sustainable EffiSludge wastewater treatment concept to the Nordic pulp- and paper industry

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Disa Donnér; [2018]
    Nyckelord :Anaerobic digestion; Biomethane; Carbon footprint; EffiSludge; Pulp- and papermill wastewater treatment; Waste activated sludge;

    Sammanfattning : The pulp- and paper industry (PPI) faces a great challenge in finding new ways to reduce its overall carbon emissions. Large quantities of water are used in the pulp- and paper making process. In this context, a more sustainable wastewater treatment with a lower carbon footprint is of relevance for the PPI. LÄS MER
