    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. LCA and LCCA in the design of geotechnical engineering works

    Författare :Ida Samuelsson; Stefan Larsson; Johan Spross; Rasmus Rempling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Life Cycle Cost Analysis; climate impact; costs; geotechnical engineering; Livscykelanalys; Livscykelkostnadsanalys; klimatpåverkan; kostnader; geoteknik; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Geotechnical engineering works are part of almost all construction and infrastructure projects. The geotechnical engineering work contributes to the impact on the environment and gives rise to costs throughout its life cycle. LÄS MER

  4. 3. Energy efficient renovation in a life cycle perspective : A case study of a Swedish multifamily-building

    Författare :Ricardo Ramirez Villegas; Ola Eriksson; Thomas Olofsson; Harpa Birgisdottir; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; renovation; greenhouse gas emissions; district heating; energy efficiency; building environmental assessment tools; energy use; space heating; life cycle assessment; life cycle costing; payback; scenarios simulation; Byggnadsrenovering; växthusgasutsläpp; fjärrvärme; energieffektivitet; system för miljöcertifiering av byggnader; energianvändning; byggnadsuppvärmning; livscykelanalys; livscykelkostnader; återbetalning; scenariosimulering; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola;

    Sammanfattning : Energy use in the European Union is increasing. At the same time, it is estimated that by the year 2050 most of the EU population will be living in currently existing buildings. Some of these buildings are or will be in need of renovation, and they have identified a target to reduce overall energy use. LÄS MER

  5. 4. Assessment of Raw Materials in Stainless Steelmaking-Their Energy Consumption and Greenhouse Gas Emission

    Författare :Wei Wenjing; Anders Tilliander; Peter Samuelsson; Pär Jönsson; Ye Guozhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static process model; mass and energy balance; molybdenum; nickel; phosphorus; stainless steel; life cycle assessment; GHG emission; energy consumption; statisk procesmodell; mass- och energibalans; molybden; nickel; fosfor; rostfritt stål; livscykelanalys; växthusgasutsläpp; energiförbrukning; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : In stainless steelmaking, around 68% of the total greenhouse gas emissions come from the processing of raw materials. Thus, it is important for steelmakers to make efforts together with their raw material suppliers to implement low-carbon initiatives. To facilitate such initiatives, assessment of raw materials will provide guidance. LÄS MER

  7. 5. 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
