  1. 1. Defining requirements of PET scrap for open loop recycling of post-industrial waste

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Josephine Digné; [2020]
    Keywords : Chemical Engineering; plastics; thermoplastics; PET; polyethylene terephthalate; foamed plastics; recycling; post-industrial waste; circular economy; återvinning; kemiteknik; Technology and Engineering;

    Abstract : To reduce the environmental impact and minimize the exploitation of the depleting re-sources, the transition to a circular economy is vital. It proposes an economy of reduced ma-terial consumption and increased reuse and recycling of plastics and other materials. READ MORE

  2. 2. Fermentation and germination of pearl millet and cowpea : a review of nutritional quality, antinutritionalcompounds and functional properties

    University essay from SLU/Department of Molecular Sciences

    Author : Stina Gustavsson; Sofia Jacobsson; [2020]
    Keywords : pearl millet; cowpea; fermentation; germination; chemical composition; antinutritional compounds; functional properties;

    Abstract : Undernutrition is responsible for 45% of deaths of children under the age of 5 in low- and middle-income countries, where pearl millet (Pennisetum glaucum) is one of the staple cereals. Despite of pearl millets favorable chemical composition, challenges still lie in the utilization of them due to the presence of antinutritional compounds (ANCs). READ MORE

  3. 3. Algae hydrocarbons designed for bio-based lubricants

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Elin Sjöhag; [2020]
    Keywords : Microalgae; macroalgae; lubricant; alginate; grease; Mikroalger; makroalger; smörjmedel; alginat; förtjockningsmedel;

    Abstract : Smörjmedel är en nödvändighet för maskiner för att minska slitage och energiförbrukning. Dock är över 95% av de använda smörjmedlen i dag fossilbaserade. Smörjmedel baserade på vegetabiliska oljor finns tillgängliga men har ofta en lägre oxidativ stabilitet och sämre lågtemperaturegenskaper än deras fossilbaserade motsvarigheter. READ MORE

  4. 4. Approaches for improving the rheological characterization of fermented dairy products

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Abdulrahman Muhammad; [2020]
    Keywords : food engineering; livsmedelsteknik; Technology and Engineering;

    Abstract : Fermented dairy products are wildly consumable products in today societies, and these products are known for their unique rheological properties due to the complex structural systems they possess. The simplest rheological model for describing yogurt behavior is the Power Law model, but this model parameters are not sufficient for describing the complex behavior during flow and filling.

  5. 5. Method development for rheological characterization of microfibrillated cellulose

    University essay from Karlstads universitet

    Author : Elin Wahlkrantz; [2020]
    Keywords : microfibrillated cellulose; MFC; rheology; characterization; dynamic rotational rheometer; complex viscosity; amplitude sweep; dry content; pH; conductivity; measuring geometry; gel; mikrofibrillerad cellulosa; MFC; reologi; karakterisering; dynamisk rotationsreometer; komplex viskositet; amplitudsvep; torrhalt; pH; konduktivitet; mätgeometri; gel;

    Abstract : This thesis contributes to a development of a method for rheological characterization of microfibrillated cellulose. The intended use of the method is to be able to distinguish between different grades of microfibrillated cellulose. READ MORE
