  1. 16. Small-scale biogas production from organic waste and application in mid-income countries – a case study of a Lebanese community

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sebastian Huber; [2019]
    Nyckelord :Sustainable Development; Lebanon; small-scale; biogas production; organic waste; liquid digestate; anaerobic digestion; feasibility study;

    Sammanfattning : The controlled anaerobic digestion of organic waste in a biogas facility aggregates advantages of waste treatment, energy recovery and nutrient recycling and is a promising technology to deal with contemporary issues of waste management and energy recovery. Small-scale biogas production units can be simply designed and successfully operated even in settings where means for advanced technology equipment are low and institutional capacities limited.

  3. 17. 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

  4. 18. Can organic waste provide sustainable fuel and energy in Rio de Janeiro? : An Early Assessment of waste-based biogas solutions in Rio de Janeiro, Brazil

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Jesper Lindmark; Lundqvist Oscar; [2019]
    Nyckelord :biogas; potential; feasibility; performance; environmental; economic; biogas solution; biogas solutions; waste-based; early assesment; multi-criteria framework; biogas; potential; genomförbarhet; prestanda; miljömässig; ekonomisk; biogaslösningar; hållbar utveckling;

    Sammanfattning : Sustainable waste management remains a great challenge for many cities throughout the world. Landfilling is worldwide the most common way of treating municipal solid waste (MSW) and landfilling of organic matter releases the high potent gas methane, which contributes to global warming.

  5. 19. 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

  7. 20. Long-term application of digestate and biofuel ash to arable soil : effects on the solubility of Cd, Al and trace metals as evidenced by simulated scenarios

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Elias Bäckström; [2018]
    Nyckelord :cadmium; fertilizer; Visual MINTEQ;

    Sammanfattning : The importance of nutrient recycling could not be emphasized enough in to-day’s society. Reduction of waste as well as recycling of nutrients would be the result if ash and biogas digestate could be used as fertilizer. However, the solubility of Cd, Al and micronutrients might be affected in a different way than by standard fertilizers. LÄS MER
