  1. 1. Anaerobic Co-digestion of Digestate with Glycerol to enhance Biogas Production

    Master-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Prince Kwarteng Adiyia; [2021]
    Nyckelord :Biogas; Anaerobic Digestion; Digestate; Glycerol;

    Sammanfattning : The Brazilian sugarcane and ethanol industries produce lot of waste which has potential for energy production. Anaerobic digestion (AD) can be effectively utilized for producing biogas from these wastes. LÄS MER

  3. 2. Comparison of Pre- and Post-treatments of Sugarcane Industry By-products to Increase Biomethane Production

    Master-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Baitong Huang; [2020]
    Nyckelord :Biomethane potential; sugarcane straw; filter cake; vinasse; co-digestion; autoclaving treatment; NaOH treatment; Brazil;

    Sammanfattning : Even though the Brazilian ethanol and sugar production system (based on sugarcane industry) have been providing large amounts of bioenergy, the extensive amounts of organic wastes generated cannot be ignored when it comes to sustainability. Using these biomasses to produce biomethane through anaerobic digestion has been proven as a promising way to tackle this issue. LÄS MER

  4. 3. A nexus in crisis: How Brazil’s push for energy security through sugarcane-based ethanol is affecting its water security

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Camila Fagundes Hubel; [2020]
    Nyckelord :Energy-water nexus; sugarcane ethanol; land use change; precipitation; sustainable development;

    Sammanfattning : As reliance on energy and water resources grow, so do the concerns regarding their security, especially in terms of availability. A projected rise in population, accompanied by the relentless pursuit of economic growth and increasing climate change, indicate that greater stress will be placed on these same resources. LÄS MER

  5. 4. Hållbar sockerrörsodling för etanolframställning i Brasilien : Hur slagkraftig är dagens hållbarhetscertifiering och kan den förändra mark- och vattenpåverkan från odlingarna?

    Uppsats för yrkesexamina på grundnivå, KTH/Industriell ekologi

    Författare :Eva Melin; Martin Alesund; [2015]
    Nyckelord :;

    Sammanfattning : Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ́s. LÄS MER

  7. 5. Economic Analysis of Hydrogen Production by Photovoltaic Electrolysis

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Luciano Gajardo; [2014]
    Nyckelord :Economic analysis; photovoltaic electrolysis system; hydrogen production cost; steam reforming;

    Sammanfattning : Awareness of the climate situation and greenhouse gas emissions from fossil fuels has focused attention on hydrogen as a renewable and sustainable energy resource. In this work an economic analysis of hydrogen production by a photovoltaic electrolysis system was conducted. LÄS MER
