1. 1. Life cycle assessment of metal laser powder bed fusion : A deep dive into the significance of system boundary expansion and improvement potential

   Master-uppsats, Linköpings universitet/Industriell miljöteknik

   Författare :Christian Rotter; Erik Fagerberg; [2023]
   Nyckelord :additive manufacturing; life cycle assessment; powder bed fusion; system boundaries; metal laser powder bed fusion; environmental impact; global warming potential;

   Sammanfattning : Metal additive manufacturing (MAM) is a manufacturing technology experiencing a rapid expansion rate. Metal laser powder bed fusion (ML-PBF) is among the most popular techniques in this field. The environmental implications of it are often discussed in literature and compared to conventional manufacturing. LÄS MER

3. 2. Greenhouse gas emissions and energy efficiency of various renewable energy pathways in the truck industry : An LCA and energy efficiency analysis on fuel production for and manufacturing of 40 tonne heavy trucks in Sweden

   Master-uppsats, Linköpings universitet/Institutionen för tema; Linköpings universitet/Filosofiska fakulteten

   Författare :Jacob Axell; [2023]
   Nyckelord :Hydrogen; Sweden; 40-tonne haulage truck; LCA; Wind energy; Bio fuel; Energy efficiency; CO2 emissions;

   Sammanfattning : This study focuses on assessing the greenhouse gas emissions and energy efficiency of 40-tonne haulage trucks in fuel production and manufacturing in a Swedish context. The aim was to provide accurate greenhouse gas accounting and evaluate the contribution to mitigating climate change. LÄS MER

4. 3. Implementing Life Cycle Assessment in the Product Development Process : Creating a simplified LCA-tool to support decision making and implement sustainability as a design parameter

   Master-uppsats, Linköpings universitet/Industriell miljöteknik

   Författare :Markus Johansson; Jonatan Sars; [2023]
   Nyckelord :;

   Sammanfattning : Design is described as the main factor influencing a product's sustainability, and with industrial growth, global interest in sustainability issues has also increased. Furthermore, the design process is an important part when companies are to reduce climate impact of their products, and that the demand for more environmentally friendly products is increasing.

5. 4. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

   Master-uppsats, Linköpings universitet/Industriell miljöteknik

   Författare :Ellen Lundin; Lovisa Liljenberg; [2023]
   Nyckelord :LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

   Sammanfattning : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. LÄS MER

7. 5. Life cycle assessment on sodium-ion cells for energy storage systems : A cradle-to-gate study including 16 environmental perspectives, focusing on climate change impact

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Rebecca Nibelius; [2023]
   Nyckelord :Sodium-ion batteries; Life cycle assessment; Cradle-to-gate; Natriumbatterier; Livscykelanalys; Vagga-till-port;

   Sammanfattning : Because of the changing energy supply landscape, with the transition towards renewable energy, an emerging demand for energy storage systems (ESS) is expected in the near future. Battery energy storage is promising to contribute to mitigate the greenhouse gas emissions, but face issues considering resource use (IEA, 2023; IRENA, 2022). LÄS MER
