  1. 1. 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

  3. 2. 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

  4. 3. The prospects of using acoustic particle separation techniques to separate heavy metals from lake- and seabed sediments

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Ohan Lundblad; [2021]
    Keywords : acoustic particle separation; ultrasound; acoustics; particle separation; akustisk partikelseparation; ultraljud; akustik; partikelseparation; akustisk partikelseparationsteknik; akustisk separationsteknik;

    Abstract : This work aims to investigate if it is realistic to use acoustic particle separation techniques for separating heavy-metals from pump-dredged seabed sediments on a large scale. A premise for the project has been that the material should undergo hydrothermal carbonization (HTC) before acoustic treatment. READ MORE

  5. 4. POLYAROMATIC HYDROCARBONS IN HYDROCHARS : HYDROTHERMAL CARBONIZATION OF SEWAGE SLUDGE

    University essay from Umeå universitet/Kemiska institutionen

    Author : Björn Sundqvist; [2021]
    Keywords : ;

    Abstract : Sewage sludge is an inevitable by-product from waste water treatment plants. Sludgemanagement is a difficult task since sludge has a high moisture content, poordewaterability and generally contain heavy metals, pharmaceutical residues,polyfluorinated alkyl substances (PFAS) and organic pollutants.

  6. 5. Hydrothermally carbonized wood as a component in biobased material for 3D-printing

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Matilda Hendeberg; [2020]
    Keywords : Hydrothermal carbonization; 3D printing; biobased materials; biodegradable;

    Abstract : Consumers put higher demands on low environmental impact from the products they use, and the materials they consist of. As a result, more research is being made on finding environmentally friendly production techniques and materials. Hydrothermal carbonization (HTC) is a relatively environmentally friendly method that has been used in this study. READ MORE
