  1. 1. 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

  2. 2. The effect of thermal pre-treatment and waste paper addition to biomethane potential of macroalgae Saccharina latissima

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Gadis Tandiyoputri; [2018]
    Nyckelord :Biomethane potential; Macroalgae; Saccharina latissima; mechanical pre-treatment; thermal pre-treatment;

    Sammanfattning : As a steady renewable energy technology, biogas is a viable alternative to reduce our dependency to fossil fuels and to prevent severe climate change. Biogas potential can be improved through combining different types of substrate and inoculum, as well as through substrate pre-treatments. LÄS MER

  3. 3. Can organic waste fuel the buses in Johannesburg? : A study of potential, feasibility, costs and environmental performance of a biomethane solution for public transport

    Master-uppsats, Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Industriell miljöteknik

    Författare :Johanna Niklasson; Linnea Bergquist Skogfors; [2018]
    Nyckelord :;

    Sammanfattning : Like many large cities, Johannesburg faces several sustainability challenges such as unsustainable use of natural resources, emissions contributing to environmental- and waste related problems. The city is a provincial transport centre, and the transport sector is responsible for a large share of the city’s energy demand and emissions. LÄS MER

  4. 4. 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

  5. 5. Power-To-Gas Concepts Integrated with Biomethane Production through Gasification of Forest Residues: Economic Evaluation

    H-uppsats, Chalmers tekniska högskola/Institutionen för rymd-

    Författare :Penpaka Kannikaporn; [2018]
    Nyckelord :biomass gasification; biomethane; power-to-gas; Sabatier reactor; methanation; biomethane; SNG; cost estimation; economic evaluation; process integration;

    Sammanfattning : Biomethane is an attractive transportation fuel due to an increase in demand of biofuels. Biomass gasification is a well-known technology used to produce biomethane from renewable feedstock, for instance, forest residues. LÄS MER
