  1. 1. Biochar and district heating : The path to negative emissions

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

    Author : Amanda Widlund; Thomas Norström; William Isaksson; Andreas Andersson; [2023]
    Keywords : biochar; pyrolysis; climate impact; carbon sink; district heating;

    Abstract : Uppsala Kommun is developing a new city district called Sydöstra staden (SÖS) as an innovative and transformative city district. A technical supply system that aligns with the district’s goals is pyrolysis. Pyrolysis is a process where biomass is heated without the supply of oxygen. READ MORE

  3. 2. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Harry Tibbetts; [2023]
    Keywords : Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

    Abstract : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). READ MORE

  4. 3. Waste-derived hard carbon anode materials for sodium-ion batteries : The potential of using cardboard as precursor material in sodium-ion batteries for hard carbon production in Sweden

    University essay from KTH/Materialvetenskap

    Author : Axel Björlin; Alexander Hansson; Yanxi Lucie Zhou; [2023]
    Keywords : ;

    Abstract : In recent years, sodium ion batteries (SIBs) have emerged as a strong contender to lithium-ion batteries (LIBs). The most promising anode for the SIBs is hard carbon (HC), which can be derived from a wide variety of raw materials and waste globally. READ MORE

  5. 4. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues

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

    Author : Abdirahman Abdullahi; [2022]
    Keywords : Technoeconomic analysis; energy system modelling; HTC; hyrochar; system integration; OSMET;

    Abstract : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. READ MORE

  6. 5. Wet spinning of carbon fiber precursors from cellulose-lignin blends in a cold NaOH(aq) solvent system

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Landmér Alice; [2022]
    Keywords : Carbon fiber; cellulose; cold NaOH aq ; lignin; precursor; sodium hydroxide; solution spinning; wet spinning;

    Abstract : Carbon fiber (CF) is predominantly produced from fossil-based sources and is therefore an area of interest for further development towards a more sustainable society. The purpose of this thesis work was to investigate the possibility of producing precursor fibers (PFs) for CF production from a blend of renewable cellulose andlignin. READ MORE
