  1. 6. Assessment of the energetic feasibility of a novel CHP biorefinery concept

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Ângelo Miguel Mendes Ferreira; [2023]
    Keywords : biorefinery; bioenergy; biomimicry; combined heat and power; Earth Power Lodge; Technology and Engineering;

    Abstract : This study investigates the potential for energetic self-reliance in an integrated biore- finery, the Earth Power Lodge (EPL), which aims to convert waste into valuable by- products through bio- and thermochemical conversion processes. The primary questions addressed include assessing the necessity of external propane to sustain the pyrolysis process and the net energy output of the ThermoChemical Reactor (TCR) process when fractional distillation is applied to the resulting bio-oils.

  3. 7. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

    University essay from KTH/Materialvetenskap

    Author : Mochen Li; [2023]
    Keywords : Photovoltaic; Molybdenum disulfide; Absorption coefficient; ab initio material design; Fotovoltaisk; Molybdendisulfid; Absorptionskoefficient; ab initio materialdesign;

    Abstract : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. READ MORE

  4. 8. Using forest reflectance modelling to estimate albedo for narrow-view satellites

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

    Author : Nick Bergmans; [2023]
    Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

    Abstract : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. READ MORE

  5. 9. A Circular Solution for Plastic Waste Within Healthcare : A fully implementable solution for creating a circular end-of-life option for plastic waste using chemical recycling

    University essay from KTH/Produktionsutveckling

    Author : Bharghav Ganesh; Iliass Temsamani; [2023]
    Keywords : ;

    Abstract : With a growing awareness of the environmental impacts associated with the disposal of healthcare plastic consumables through conventional end-of-life methods, such as landfilling and incineration, there is an increasing need to adopt more sustainable practices. This thesis explores the development of an alternative, circular economy-based solution to manage plastic waste generated by the healthcare sector, focusing on the identification of circular end-of-life strategies.

  6. 10. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Robert Liao; [2023]
    Keywords : ;

    Abstract : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.
