1. 11. Causes of and solutions to reduce excess material in production processes : A study of electrical motors and generators at ABB Machines

   University essay from Linköpings universitet/Industriell miljöteknik

   Author : Wilma Fager; Hanna Engberg; [2023]
   Keywords : Excess material; investigation; production processes; reduce; material usage; minimize; components;

   Abstract : This thesis focus on the investigation of material usage in the production processes of electrical motors and generators at ABB Machines, a company based in Västerås, Sweden. The study aims to understand the reasons for the occurrence of excess material after the assembly of a motor or generator and explore possible solutions to minimize its occurrence. READ MORE

3. 12. Reduced Greenhouse Gas Emissions from Transport Infrastructure Construction : Reaching the Swedish Transport Administration's climate reduction targets with greenhouse gas reduction measures in the production phase of the most recurring materials

   University essay from Linköpings universitet/Industriell miljöteknik

   Author : Pontus Sallerström; Sam Falakeh; [2023]
   Keywords : Transport infrastructure; Swedish Transport Administration; Greenhouse gas; Transport construction sector; LCA; Industrial Ecology; Transportinfrastruktur; Trafikverket; Växthusgas; Transportbyggnadssektorn; LCA; Industriell ekologi; Klimatkalkyl;

   Abstract : I Sverige står byggsektorn för 25% av landets totala utsläpp av växthusgaser, där material står för mer än hälften av dessa utsläpp [1][2][3]. De största bidragsgivarna är stål och betong, men även material som aluminium och asfalt har en betydande miljöpåverkan. READ MORE

4. 13. Conditions for Circular Electric Vehicle Battery Value Chains : Exploring Opportunities for Circular Economy Implementation in the Value Chain of Electric Vehicle Batteries in Nairobi, Kenya

   University essay from Linköpings universitet/Industriell miljöteknik

   Author : Johanna Hegenbart; Sofie Rosmark; [2023]
   Keywords : Circular Economy; Electric Vehicle Batteries; Sustainability; Ecosystem;

   Abstract : To reduce the negative impacts of climate change, electric vehicles (EVs) have emerged as a viable solution in the mobility sector, leading to an increase in battery production and use. For electric vehicle batteries (EVBs) to be sustainable, the total impact of the supply and value chain has to be as low as possible, making the implementation of circular economy (CE) principles a key element in the transition.
