  1. 1. 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.

    Sammanfattning : Surface water is globally becoming more and more a scarce resource, and in Addis Ababa the capital of Ethiopia, river water quality has been degraded due to anthropological forcing for many years. Therefore, the study objective was to investigate causes and impact of surface water pollution in Kebena and Great Akaki rivers. LÄS MER

  3. 3. Methods for Evaluating Dewatering Properties of Sewage Sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Nadia Abdalla; [2019]
    Nyckelord :sludge dewatering; sewage sludge; laboratory scale sludge treatment; dewatering sludge; dewatering sewage sludge; CST; capillary suction time test; centrifuge; lab-centrifuge; rheology; polymers conditioning; sludge conditioning; centrifuge on lab scale; evaluation of lab experiments; CST evaluation; mechanical de-watering evaluation; sludge dewatering at lab; lab scale dewatering process; sludge dewatering methods at lab; Chemical engineering; Lab centrifuge; Capillary Suction Time CST ; Mechanical sludge dewatering evaluation; Polymers conditioning of sludge; sewage sludge dewatering; methods for sludge dewatering at lab; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Sammanfattning : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. LÄS MER

  4. 4. 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

  5. 5. Differences between urban and landfill citizens in the An Giang province of Vietnam : - a field study about landfilling & solid waste management

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Nina Jonsson; [2019]
    Nyckelord :Developing countries; Landfill; Mekong delta; Solid Waste Management; Vietnam; An Giang;

    Sammanfattning : Landfilling is the most common treatment of Municipal Solid Waste (MSW) in the An Giang province in south Vietnam. Many of the landfills are not sanitary and can be harmful to the environment and the residents, especially those who live within the settled distance limit of 1000 meters. LÄS MER
