  1. 11. 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

  3. 12. Evaluation of a computational method for natural fiber-reinforced plastics

    University essay from KTH/Hållfasthetslära

    Author : Anna Lim; [2023]
    Keywords : PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Abstract : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. READ MORE

  4. 13. Microplastics in Scanian wetlands : Sege river & Kävlinge river

    University essay from Malmö universitet/Institutionen för Urbana Studier (US)

    Author : Ludvig Stoltz; Pernilla Leijon; [2023]
    Keywords : plastic pollution; wetlands; microplastics; Scania; density separation; plastföroreningar; våtmarker; mikroplaster; Skåne; flotteringsmetod;

    Abstract : It is estimated that 75 million tons of plastics waste is currently in the ocean and expects to increase in line with plastic consumption. Plastic items in natural or aquatic environments are fragmented into smaller pieces called microplastics. Microplastics can enter rivers and lakes through sewage water to end up in wetlands where they sediment. READ MORE

  5. 14. Design, Analysis and Performance Evaluation of Indirect Solar Dryer

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Tandin Jamtsho; [2023]
    Keywords : Technology and Engineering;

    Abstract : Food production is a critical component of global livelihoods and economic revenue. However, storing harvested food presents challenges in minimizing post-harvest losses. Among various methods, food drying has emerged as a popular technique for preserving food during off-seasons. READ MORE

  6. 15. Continuous Fibre Reinforcements in Injection Moulded Composites

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Erik Björkqvist; [2023]
    Keywords : Injection moulding; Plastics; Thermoplastics; Fibre Reinforcement; FEM; Formsprutning; Plast; Termoplast; Fiberarmering; FEM;

    Abstract : The use of continuously reinforced thermoplastics have increased in recent years andoffer some significant advantages over their thermoset counterparts. The utilizationof these materials is however still limited due to the labour intensive processingand manufacturing. READ MORE
