1. 1. Profitability During a Sustainability Transformation - A Case Study of a Swedish Petroleum and Biofuel Company

   Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

   Författare :Michael Crona; Filip Linnér; [2023-02-27]
   Nyckelord :This report examines the financial profitability of a petroleum and biofuel company during their sustainability transformation. The case company is Preem AB; the largest fuel company in Sweden. The study finds that debt-to-equity ratios tend to increase with investments in more sustainable solutions. This could propose a higher financial risk to the firm. The report also proposes and discuss the use of metrics for CO2- emission that are easier to understand than just the weight of the gas emitted. Preem does not seem to benefit from being part of the European Union’s Emissions Trading System ETS ; since their green investments are focused on reducing emissions in the use phase of their products; not in the production phase; which is what the ETS measures and rewards. The case study is based on an interview with a director at Preem to get an insight to the green investments. Data for financial- and environmental performance are collected from official reports published by Preem.;

   Sammanfattning : This report examines the financial profitability of a petroleum and biofuel company during their sustainability transformation. The case company is Preem AB, the largest fuel company in Sweden. The study finds that debt-to-equity ratios tend to increase with investments in more sustainable solutions. LÄS MER

4. 3. Utilization of Biomethane in Decarbonising India´s Energy Mix

   Master-uppsats, KTH/Energiteknik

   Författare :Niraj Ravindra Kunkulol; [2023]
   Nyckelord :Anaerobic digestion; biogas; biomethane; membrane filtration; pressure swing adsorption; Anaerob rötning; biogas; biometan; membranfiltrering; trycksvängadsorption;

   Sammanfattning : This thesis investigates the potential of biomethane production in India, the impact of its integration into the energy mix, and the corresponding Greenhouse Gases (GHG) emission and potential reduction. India, with its huge population and being an agriculturally rich country, produces gigantic amounts of biodegradable waste from various sources such as Municipal Solid Waste (MSW),agricultural waste, animal husbandry, sugar industry, etc. LÄS MER

5. 4. 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

7. 5. Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Linnea Sjökvist; [2023]
   Nyckelord :Membrane filtration; ultrafiltration; PHA; polyhydroxyalkanoates; chemical engineering; Technology and Engineering;

   Sammanfattning : Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. LÄS MER
