  1. 1. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Simon Dahl; [2023]
    Keywords : Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

  3. 2. Modeling of an Electrolysis System for Techno-Economic Optimization of Hydrogen Production

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

    Author : Jürgen Köstlbacher; [2023]
    Keywords : Hydrogen; Hydrogen Production; Green Hydrogen; LCOH; Electrolysis; PEM; AEL; MILP; Optimization; Techno-Economic Analysis; Cost Optimization; PPA; vätgas; vätgasproduktion; grön vätgas; LCOH; elektrolys; PEM; AEL; MILP; optimering; tekniskekonomisk analys; kostnadsoptimering; PPA;

    Abstract : In face of climate change, Europe and other global actors are in the process of transitioning to carbon-neutral economies, aiming to phase out of fossil fuels and power industries with renewable energies. Hydrogen is going to play a crucial role in the transition, replacing fossil fuels in hard-to-decarbonize industries and acting as energy carrier and energy storage for renewable electricity.

    Keywords : Decarbonization; Fossil-free Hydrogen; Green Hydrogen; Hydrogen Economy; System Thinking; Sustainable Development;

    Abstract : Hydrogen is under the spotlight due to its ability to decarbonize the hard-to-abate sector. Sweden, which aims to achieve net zero emissions by 2025, has incorporated hydrogen as an instrument to reach a decarbonization pathway. READ MORE

  5. 4. Analysis of Process Technologies to Preserve Berries

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Jose Abraham Zamudio Pedraza; [2022]
    Keywords : berry processing; freezing; drying; lyophilization; microwave vacuum drying; osmotic dehydration; environmental impact; food engineering; Agriculture and Food Sciences;

    Abstract : From all the wild berries that grow in Sweden only 2-5% is utilized (RISE, 2022). The United Nation has 17 goals for sustainable development, and many of those goals are related to sustainable food production (United Nations, 2022). READ MORE

  6. 5. Feasibility Study of Available Hydrogen Production Techniques in Sweden using Single-Issue LCA Carbon Footprint

    University essay from KTH/Industriell bioteknologi

    Author : Beatrice Westén; [2022]
    Keywords : Hydrogen; biohydrogen; LCA; Single-Issue LCA; streamlined LCA; Life Cycle Assessment; Carbon Footprint; CF; Environmental System Analysis; Sweden; holistic; future scenarios; Vätgas; biovätgas; LCA; Single-Issue LCA; streamlined LCA; Life Cycle Assessment; Carbon Footprint; CF; Environmental System Analysis; Sverige; holistisk; framtida scenarios;

    Abstract : Sverige har som mål att bli helt fossilfri till år 2045. Energymyndigheten har därför tagit fram ett förslag till Vätgasstrategi för att ställa om vätgasproduktionen till att vara helt fossilfri till 2045. Idag används ca 180 000 ton vätgas, vilket motsvarar ett energiinnehåll på ca 6 TWh. READ MORE
