    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. 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

  4. 3. Biocarbon for fossil coal replacement

    Författare :Aekjuthon Phounglamcheik; Kentaro Umeki; Mašek Ondřej; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass pyrolysis; charcoal; bio-oil recycling; CO2 utilization; reactivity; rotary drum; Energiteknik; Energy Engineering;

    Sammanfattning : This research aims to provide a full view of knowledge in charcoal production for fossil coal replacement. Charcoal from biomass is a promising material to replace fossil coal, which is using as heating source or reactant in the industrial sector. LÄS MER
