  1. 1. Value of CO2 neutrality for sustainable engineering steel: A case study of Ovako AB

    University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Author : Erik Larsson; Filip Smith; [2022]
    Keywords : Automotive; Battery electric vehicle; Bearing; Blast furnace; Carbon border adjustment mechanism; Carbon dioxide; Electric arc furnace; Emissions trading system; Engineering steel; Green steel; Greenhouse gas; Innovation; Internal combustion engine; Life cycle analysis; Mining; Paris agreement; Science based target initiative; Steel; Sustainability; Sustainable steel; Triple bottom line;

    Abstract : Steel production is today one of the most CO2-demanding activities and causes 8% of the global emissions of GHG. It is crucial for the industry to reduce its emissions radically in order to be in line with the goals of the Paris Agreement and the Science-Based Target initiative. READ MORE

  3. 2. Sustainable concrete bridges : An investigation of possible measures to reduce the climate impact

    Abstract : The need of building new bridges is always existing in relation with the increase of infrastructureand transport needs. Bridge constructions have traditionally been associated with highconsumption of resources and large greenhouse gas emissions. READ MORE

  4. 3. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anton Sundström; [2020]
    Keywords : DEM; Discrete element method;

    Abstract : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. READ MORE
