  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. Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Linnea Sjökvist; [2023]
    Keywords : Membrane filtration; ultrafiltration; PHA; polyhydroxyalkanoates; chemical engineering; Technology and Engineering;

    Abstract : Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. READ MORE

  4. 3. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.

    University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Author : Regan George; [2023]
    Keywords : PHA; HTC-substrate; Polymer;

    Abstract : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.

  5. 4. Mapping of Process Hazard Analyses in Swedish Process Industries and How the Work Can Be Improved

    University essay from Lunds universitet/Riskhantering (CI)

    Author : Isabella Bergström; [2022]
    Keywords : Risk management; Qualitative risk assessment; PHA; Process safety; Seveso directive; Technology and Engineering;

    Abstract : This study aims to map how Swedish process industries use qualitative risk analyses, such as process hazard analyses (PHA), to assess risks. Beyond the Seveso legislation, which requires all facilities classified as upper tier to perform a safety report each fifth years, there are no Swedish legislation or regulations regarding how and when PHAs should be executed.

  6. 5. Evaluation of using bioplastics for lab consumables

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Lovisa Mäepea Nilsson; Emelie Gunnarsson; Sara Mardini; Fartun Nuur Yusuf; Jesper Nyström; [2022]
    Keywords : bioplastics; Biotage; sustainability; green washing; biopolymers; PLA; bio-based; environment; PHA; PP; PE; chemical properties; bioplaster; hållbarhet; bio-polymerer; bio-baserad; miljövänlig;

    Abstract : The use of plastic has increased markedly in recent years which has led to more fossil fuels being used and more plastic in nature. This is a literature study that researches on how bio- based plastics can be used instead of plastics made from fossil fuels. READ MORE
