    Sammanfattning : Biochar – the carbon rich residue derived from biomass pyrolysis – is recognised as a potential solution to remove carbon dioxide from the atmosphere, while simultaneously delivering socio-environmental benefits through biochar use as a material. Perceived as a sustainable innovation, biochar has raised interest throughout the world. LÄS MER

  3. 2. Sustainable valorization of Biomass into Syngas/H2 via Biocarbon catalyst

    Författare :Hanmin Yang; Weihong Yang; Pär Jönsson; Linda Sandström; Chunfei Wu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Catalytic upgrading; Biomass; Biochar; Syngas; Hydrogen; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Environmental issues stemming from the rapid growth in global energy demand and carbon dioxide emissions require urgent resolutions. Biomass represents a viable alternative for displacing fossil fuels, as its energy can be converted into electricity, heat, fuels, and chemical precursors, thus substituting petrochemicals. LÄS MER

  4. 3. Emerging technologies for climate-neutral urban areas : An Industrial Ecology perspective

    Författare :Asterios Papageorgiou; Cecilia Sundberg; Rajib Sinha; Maria Malmström; Ola Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban areas; climate neutrality; solar microgrid; biochar; Life Cycle Assessment; Material and Energy Flow Analysis; Substance Flow Analysis; Urbana områden; klimatneutralitet; solmikronät; biokol; livscykelanalys; material- och energiflödesanalys; substansflödesanalyss; Industrial Ecology; Industriell ekologi;

    Sammanfattning : The ever-increasing concentration of human activity in urban areas induces environmental problems beyond their boundaries on scales ranging from local to regional to global, such as resource depletion, land degradation, air and water pollution and climate change. Human-induced climate change is widely acknowledged as one of the greatest sustainability challenges of the present century and it is inextricably linked to urbanization. LÄS MER

  5. 4. Fortification of soil-based wastewater treatment systems with versatile ubiquitous reactive media for enhanced removal of phosphorus and other pollutants

    Författare :Ezekiel Kholoma; Gunno Renman; Agnieszka Renman; Haniso Motlhabane; Mark Healy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochar; Fortified filter; Gas concrete; Phosphorus removal; Reactive filter media; Wastewater treatment; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Concerns about potential risks posed by discharge from small-scale wastewater treatment (SWT) systems to receiving water bodies have prompted robust enforcement of national discharge quality standards in rural areas of most developed countries. Consequently, communities in such places are in need of effective technologies with which to achieve compliance. LÄS MER

  7. 5. Modeling the Potential for Carbon Removal in Agriculture: Integrating Farmer Perspectives

    Författare :Andreas Rehn; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Crop Rotation; Climate Change Mitigation; Carbon Dioxide Removal CDR Agricultural Practices; Stakeholder participation; Perennial Ley Crops; Biochar; Soil Organic Carbon SOC ; Landscape Modeling;

    Sammanfattning : The overarching aim of this thesis is to provide insights into the dynamic processes governing SOC stocks and to identify viable paths for agricultural systems to contribute to climate change mitigation. By integrating current scientific knowledge of carbon sequestration in agriculture with feasible agricultural applications, this work proposes local realistic strategies for enhancing soil organic carbon (SOC) and presents a quantitative assessment of their potential for CO2 removal.
