  1. 1. Sustainability Filtration and Optimization: A Stepwise Integration Approach

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Soroosh Jalaei; [2023]
    Nyckelord :Sustainability; Modern Portfolio Theory; Optimization; Sequential Quadratic Programming; Optimal ESG Portfolio.; Hållbarhet; Modern portföljteori; Optimering; Sequential Quadratic Programming; Optimal ESG-portfölj.;

    Sammanfattning : This thesis explores the integration of sustainability into Modern Portfolio Theory (MPT) optimization by introducing stepwise filtration and optimization. This study acknowledges the growing importance of sustainability in investment strategies and modifies the traditional MPT framework to include environmental, social, and governance (ESG) factors.

  3. 2. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Lina Näslund; Gabriella Petersson; [2023]
    Nyckelord :Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

  4. 3. Investigation of flux dependence on viscosity in ultrafiltration

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Peter Bourghardt; [2023]
    Nyckelord :ultrafiltration; viscosity; molasess; konjac glucomannan; comsol; LabStak M39; membrane; filtration; chemical engineering; Chemistry;

    Sammanfattning : This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. LÄS MER

  5. 4. Cultivation of Yarrowia lipolytica on a hydrolysate based on food waste

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Hanna Norrman; [2023]
    Nyckelord :Yarrowia lipolytica; hydrolysate; food waste; fish feed; volatile fatty acids;

    Sammanfattning : Interest in replacing fish oil and fish meal as fish feed ingredients with more socially, environmen-tally, and economically sustainable alternatives has increased in recent years. One such alternative could be the use of yeast biomass. LÄS MER

  7. 5. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Fanny Blom; [2022]
    Nyckelord :wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Sammanfattning : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. LÄS MER
