  1. 1. 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

  2. 2. Hydrothermally carbonized wood as a component in biobased material for 3D-printing

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

    Author : Matilda Hendeberg; [2020]
    Keywords : Hydrothermal carbonization; 3D printing; biobased materials; biodegradable;

    Abstract : Consumers put higher demands on low environmental impact from the products they use, and the materials they consist of. As a result, more research is being made on finding environmentally friendly production techniques and materials. Hydrothermal carbonization (HTC) is a relatively environmentally friendly method that has been used in this study. READ MORE

  3. 3. Characterization of microplastics in wastewater

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Lina Sabienski; [2020]
    Keywords : ATR-FTIR spectroscopy; Microplastic; Plastic pollution; Visual characterization; Wastewater effluent; Wastewater treatment plant WWTP ;

    Abstract : This study aims to detect how many microplastics and what kind are released from the wastewater treatment plant (WWTP) Skebäck, in Örebro. The study was limited to the analysis of three filters with 50 μm mesh size and one filter with 300 μm mesh size. READ MORE

  4. 4. Mechanism of Formation of Soft Particles in Biodiesel Fuel Blends

    University essay from KTH/Materialvetenskap

    Author : Roberta Maria Fiorenza; [2020]
    Keywords : ;

    Abstract : The large environmental impact related to the use of fossil fuel has driven the shift toward renewable sourced alternatives. Fossil diesel can be nowadays replaced by biodiesel, obtained from vegetable oils and fats, mostly used as biodiesel blends. READ MORE

  5. 5. Modified lignin as replacement of carbon black in elastomers- For the development of sustainable tyre technology : The substitution of carbon black with modified lignin- Green tyre technology

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Mostafa Ahmed Ismail; [2020]
    Keywords : lignin; tyre rubber; elastomeric materials; esterfication;

    Abstract : Due to its large flexibility, low-price, large availability, and properties lignin is seen as an important compound with a wide range of applications. The increasing demand of fossil-based rubber materials is causing a serious threat to the environment and it is contributing to plastic- and marine pollution, ozone depletion and carbon dioxide emission (CO2) [1,2].
