1. 21. Life cycle assessment of flat glass and the implications of thinner and stronger glass

   University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

   Author : Daniel Chima; [2023]
   Keywords : Soda-Lime Glass SLS ; Thermal Strengthening; Chemical Strengthening; Life Cycle Analysis.;

   Abstract : In the production of glass, the addition of more cullet to the batch of glass and the reduction of the thickness of glass are means to reduce energy consumption and raw material usage. This contributes towards improved energy efficiency targets of the European Union. READ MORE

3. 22. 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.

4. 23. CO2 Sequestration by Bio-Accelerated Silicate Weathering

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Tora Uebel; Elisabeth Odelius; [2023]
   Keywords : enhanced silicate weathering; microorganisms; negative emission technology; CO2 emissions;

   Abstract : Human-caused emissions of CO2 and other greenhouse gases are an established reason for the climate changes that affect planet Earth. Negative emission technologies (NETs), for example, bio-accelerated silicate weathering bioreactors, seek to capture and store carbon from the atmosphere. READ MORE

5. 24. Accelerating the Green Transition - Investigating the Feasibility of E-Fuel Production Connected to a CHP Plant

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Johanna Scholtz; Alice Maillard; [2023]
   Keywords : CCU; CHP plant; e-fuels; e-methane; e-methanol; e-kerosene; Technology and Engineering;

   Abstract : The overall purpose of this thesis is to investigate the feasibility of producing electrofuels from CO2 and H2 in connection to a CHP plant equipped with carbon capture technology. This is done by investigating the production of e-methane, e-methanol and e-kerosene from captured CO2 and H2 produced from electrolysis. READ MORE

6. 25. Fouling modelling in a UHT unit based on plant data.

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

   Author : Thai Lam; [2023]
   Keywords : UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. READ MORE
