  1. 1. Utilization of Biomethane in Decarbonising India´s Energy Mix

    Master-uppsats, KTH/Energiteknik

    Författare :Niraj Ravindra Kunkulol; [2023]
    Nyckelord :Anaerobic digestion; biogas; biomethane; membrane filtration; pressure swing adsorption; Anaerob rötning; biogas; biometan; membranfiltrering; trycksvängadsorption;

    Sammanfattning : This thesis investigates the potential of biomethane production in India, the impact of its integration into the energy mix, and the corresponding Greenhouse Gases (GHG) emission and potential reduction. India, with its huge population and being an agriculturally rich country, produces gigantic amounts of biodegradable waste from various sources such as Municipal Solid Waste (MSW),agricultural waste, animal husbandry, sugar industry, etc. LÄS MER

  3. 2. A Climate, Land, Energy, and Water Nexus Assessment of Ethiopia

    Master-uppsats, KTH/Energisystem

    Författare :Pegah Atarian; [2023]
    Nyckelord :;

    Sammanfattning : Ethiopia is a landlocked country located in northeast Africa with a predominantly rural population dependent on rainfed agriculture and traditional biomass. The Ethiopian economy is growing fast and as it continues to grow, so does the demand for water, food, and energy. LÄS MER

  4. 3. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

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

    Författare :Robert Liao; [2023]
    Nyckelord :;

    Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  5. 4. Agricultural waste and wood waste for pyrolysis and biochar : An assessment for Rwanda​

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

    Författare :Jenny Eliasson; Viktor Carlsson; [2020]
    Nyckelord :Biochar; Pyrolysis; Biochar feedstock characteristics; Agricultural waste; Composition crop residues; Wood waste; Agricultural production Rwanda; Ultimate analysis; Structural composition; Heating Value; RPR; Biokol; Pyrolysis; Råmaterialegenskaper biokol; Jordbruksavfall​; Sammansättning jordbruksavfall; Träavfall; Jordbruksproduktion Rwanda; Värmevärde;

    Sammanfattning : A high priority in order to combat climate change is disposal of waste. In low-income countries, a large portion of biomass residues generated in the forestry, agricultural and industrial sectors could be usable, instead of being seen as waste. For instance, it could be converted into biochar, which is proven to have many environmental benefits. LÄS MER

  7. 5. Use of Agricultural Wastes as Supplementary Cementitious Materials

    Master-uppsats, KTH/Byggvetenskap

    Författare :Ezio Marchetti; [2020]
    Nyckelord :Agricultural waste; Environmental impact; Concrete; Life Cycle Assessment; Oat husk ash; Rice husk ash; Supplementary cementitious materials; Sustainable Construction; Betong; Havreskalaska; Hållbar konstruktion; Jordbruksavfall; Kompletterande cementmaterial; Livscykelanalys; Miljövarudeklaration; Miljöpåverkan; Risskalaska;

    Sammanfattning : Global cement production is continuously increasing from 1990 till 2050 and growing particularly rapidly in developing countries, where it represents a crucial element for infrastructure development and industrialisation. Every tonne of ordinary Portland cement (OPC) produced releases, on average, about 800 kg of CO2 into the atmosphere, or, in total, the overall production of cement represents roughly 7% of all man-made carbon emissions.
