  1. 1. Challenges and organizational capabilities to implement circularity in the automotive industry. A multiple case study

    University essay from Göteborgs universitet/Graduate School

    Author : Edoardo Galassi; [2023-07-19]
    Keywords : circular economy; circularity; circular business model; capabilities; automotive industry;

    Abstract : The market for electric vehicles has been growing rapidly in recent years. As a result, the largest share of emissions along the life cycle of vehicles will no longer come from the combustion of waste gases but from manufacturing materials. READ MORE

  3. 2. Carbon Capture from Biomass Boiler Flue Gas Emissions using Microalgae : A Case Study

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

    Author : Graham Kirn; [2023]
    Keywords : ;

    Abstract : Capture and storage of carbon dioxide (CO2) is expected to play an important role in climate change mitigation efforts intended to limit global warming to 1.5 °C. Bioenergy with carbon capture and storage (BECCS), in which carbon is captured during energy generation from sustainably sourced biomass fuels, is of particular interest in Sweden. READ MORE

  4. 3. 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.

  5. 4. Dynamic Modeling of Heat Power System : Modeling of a Heat Power System Using Physical and Data-driven Methods and Investigation of a Moving Boundary Method

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Albin Gustafsson; [2023]
    Keywords : System identification; Dynamic modeling; Organic Rankine cycle; Moving boundary; Thermodynamics.; System identifikation; Dynamisk modellering; Organisk Rankinecykel; Rörliga randvillkor; Termodynamik.;

    Abstract : Our society is becoming more and more electrified every day. However, a significant portion of the world’s electricity generation relies on the combustion of fossil fuels to produce heat, which is subsequently harnessed to generate electricity. One way of generating electricity from heat is by utilizing a Rankine cycle. READ MORE

  6. 5. 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.
