  1. 21. Construction and Characterization of 3rd Generation Saccharomyces cerevisiae Strains for PHB production form Xylose

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Pálína Haraldsdóttir; [2018]
    Keywords : Applied microbiology; Teknisk mikrobiologi; Technology and Engineering;

    Abstract : Poly-3-D-hydroxybutyrate (PHB) is a biopolymer naturally produced by a range of bacterial species. PHB production both from glucose and xylose has also been enabled by engineering the robust baker’s yeast Saccharomyces cerevisiae, however yields remain low. In the present study, additional modifications were carried out in S. READ MORE

  3. 22. Production of bio-plastic materials from apple pomace : A new application for the waste material

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Jesper Gustafsson; Mikael Landberg; [2018]
    Keywords : Apple pomace; Orange pomace; Biodegradable; Plastics; Mechanical properties;

    Abstract : Extensive quantities of apple pomace are generated annually but disposal of this waste is still much disputed. In EU alone, 500 000 tons are produced every year. Without further treatment, the acidic character of apples with their high sugar and low protein content makes the pomace unsuitable for landfilling and animal feedstock. READ MORE

  4. 23. What to Make of Waste : Material Driven Design for Better Palm Oil Practices

    University essay from Högskolan i Gävle/Design och formgivning

    Author : Anton Torlén; [2018]
    Keywords : material driven design; palm oil; Thailand; biomass waste; natural fibers; bioplastics; sustainability; 3D-printing; composites;

    Abstract : Palm oil production create a number of solid biomass waste products, in particular empty fruit bunches and mesocarp fiber; two cellulosic plant materials that are under-utilized and a source of environmental pollution today. Their fibred structure are interesting from an industrial design perspective as similar waste products from industrialized crops are used to create composite materials. READ MORE

  5. 24. Managing Household Plastic Waste: Evaluation of the EU commission’s strategy from the perspective of Swedish municipalities
