  1. 1. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Felix Hansen; Mathias Berglund; [2023]
    Keywords : Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

    Abstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE

  4. 3. Climate change mitigation from biochar production at farm level : A time dynamic LCA study of wheat

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Louise Jungefeldt; [2022]
    Keywords : Pyrolysis; agricultural by-products; life cycle assessment; waste valorization; carbon sequestration;

    Abstract : Agricultural production in Sweden account for a large contribution of the territorial GHG emissions. System optimization, fossil fuel removal and increased circularity is therefore of great importance in order to reach the national net zero emission target by 2045. READ MORE

  5. 4. Carbon Stability of Biochar : Methods for assessment and indication

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Helena Söderqvist; [2019]
    Keywords : Biochar; Stability; MRT; Carbon sink; Carbon stability; Negative emissions technology NET ;

    Abstract : Biochar can reduce the amount of CO2 in the atmosphere and is acknowledged as one feasible technology for negative carbon emissions. The stability of carbon in biochar is of major importance for the carbon sequestration value. A method for confident estimation of the stability is needed to make efficient priorities for the climate. READ MORE
