  2. 16. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

    Author : Eva Ståhl Wernersson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

    Abstract : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. READ MORE

  4. 17. From Waste to Wealth: Transforming Biorefineries into Platforms to Valorize Low-Quality Residues

    Author : Miguel Sanchis Sebastia; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; Animal Bedding; Waste Textiles; Biomass; Biotechnology; Process Design;

    Abstract : The transition to a bioeconomy, in which resources from biowaste could be reclaimed for the production of chemicals, materials or fuels, could contribute to the establishment of a sustainable society by replacing fossil fuels as raw materials. The core of this bioeconomy would be biorefineries, which are similar to petroleum-based refineries, but are facilities where biowaste is processed and refined through different chemical and/or biochemical processes.

  5. 18. Use of pre-treatments and substrate blending to enhance process efficiency in black soldier fly larvae composting of food industry waste

    Author : Alice Isibika; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Black soldier fly larvae (BSFL) composting is a biowaste treatment that converts biomass into valuable animal protein and fertiliser, but low protein content and complex molecules (e.g. fibre) in substrate reduce BSFL composting efficiency. This thesis evaluated the impact of using pre-treatments and blending substrates on BSFL process efficiency. READ MORE

  6. 19. Biochemical modification of wood components

    Author : Peter Josefsson; Lars Wågberg; Mark Rutland; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The degradation of cellulose found in wood is one of the most important degradation processes for the carbon flux on earth. The degradation is performed by microorganisms that typically use enzymes. READ MORE

  7. 20. Developments in Feedstock Analysis and Process Control for Biogas Production

    Author : Sten Strömberg; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Process control; Biochemical Methane Potential; Process analysis; Feedstock; Biogas;

    Abstract : A sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production. READ MORE
