  1. 1. Sustainable food packaging based on polyhydroxyalkanoate

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Safana Al-Ashor; [2024]
    Keywords : Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Abstract : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. READ MORE

  3. 2. Screening pyrolysis bio-oil as binder for carbon anode in aluminium production

    University essay from KTH/Fiber- och polymerteknologi

    Author : Yazhe Wang; [2023]
    Keywords : Biomass; Bio-oil; Bio-pitch; Carbon Anode; Aluminum production; Biomassa; Bioolja; Biobeck; Kolanod; Aluminium Produktion;

    Abstract : Den högkvalitativa stenkolstjäran, som används som anodbindemedel inom aluminiumindustrin, innebär utmaningar när det gäller att möta kraven på kolanod. Dess produktion är beroende av ohållbara fossila bränslen, vilket bidrar till ökade koldioxidutsläpp. READ MORE

  4. 3. The mechanism behind internal injector deposits

    University essay from KTH/Kemiteknik

    Author : Jenny Blomberg; [2023]
    Keywords : Biodiesel; deposit formation; engine oil; calcium sulphate; internal diesel injector deposits; Biodiesel; beläggningsbildning; motorolja; kalciumsulfat; interna dieselinjektorbeläggningar;

    Abstract : Användningen av biobränslen har ökat för att minska utsläppen från fossila bränslen. Biobränslen kan dock leda till beläggningar inuti injektorn, vilka påverkar fordonets  körbarhet. READ MORE

  5. 4. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Elise Meurs; [2023]
    Keywords : Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

    Abstract : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.

  6. 5. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

    University essay from KTH/Kemiteknik

    Author : Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
    Keywords : Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

    Abstract : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. READ MORE
