  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. Combustibility study of resin for warm magnet coils used at CERN

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Juan Carlos Lopez Santiago; [2023]
    Keywords : Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Abstract : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. READ MORE

  4. 3. Investigation of acidic chemical recycling of poly(acetal-ester)s

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Saga Vesterbacka; [2023]
    Keywords : Poly actetal-ester s; Chemical plastic recycling; Hydrolysis; Acidic degradation; Akestra; PHVT; Re-polymerization; Polymer technology; Chemistry;

    Abstract : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. READ MORE

  5. 4. In-plane Wetting in Packaging Material and its Consequences for Cap Performance

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Ellinor Carolina Salomonsson; [2023]
    Keywords : Tetra Pak®; Aseptic; Paperboard; Pre-laminated hole; Edge wicking; In-plane wetting; Hydrogen peroxide; Cap detachment; Polymer technology; Technology and Engineering;

    Abstract : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. READ MORE

  6. 5. Synergistic fire- and mechanical effect of biochar and ammonium polyphosphate in epoxy composite

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

    Author : Anton Olausson; Ludvig Jönsson; [2023]
    Keywords : Ammonium polyphosphate; Biochar; Composite; Epoxy; Synergistic effect;

    Abstract : Polymer composites are used in a varying extent and are challenging the use of traditional materials due to the push towards sustainable development. They have replaced steels and aluminum alloys in applications. READ MORE
