  1. 6. 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. 7. 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

  4. 8. Kommunal tillsyn som rör plastmaterial i kontakt med livsmedel i Norrköpings kommun

    University essay from SLU/Dept. of Energy and Technology

    Author : Bashar Rashoud; [2023]
    Keywords : kontaktmaterial; livsmedel; FCM; tillsyn; migration; plast;

    Abstract : I samband med en inspektion i Norrköpings kommun, uppmärksammades att kontroll av material som kommer i kontakt med livsmedel behöver mer kontroll. Via min roll som miljö-/hälsoskyddsinspektör på livsmedelsenheten i Norrköpings kommun initierade jag därför den här studien med syfte att få en övergripande bild av hur väl livsmedelsverksamheter i Norrköping uppfyller lagstiftningens krav när det gäller material och produkter avsedda att komma i kontakt med livsmedel.

  5. 9. Evaluation of Woodmer/plastic composites

    University essay from KTH/Fiber- och polymerteknologi

    Author : Leon Ahlström; [2023]
    Keywords : Extrusion; Woodmer; Flame test; Tensile test; Composites; Extrudering; Woodmer; Flamtest; Dragtest; Kompositer;

    Abstract : Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. READ MORE

  6. 10. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Anna Wagne; [2023]
    Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Abstract : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. READ MORE
