    Abstract : Ökningen av världspopulationen har orsakat en ökad avfallsgenerering. Avfallet kan innehålla betydelsefulla ämnen, vilka kan användas som råvaror i många olika material och för olika ändamål. READ MORE

  3. 3. Stroller Service System : How to make customer products sustainable within the planetary boundaries - using the case product ‘stroller’, PSS and a Design Thinking approach

    University essay from Linköpings universitet/Maskinkonstruktion

    Author : Gustav Thorslund; [2019]
    Keywords : Product Service System; PSS; Circular Economy; Service Design; Sustainability; Planetary Boundaries; Stroller; Design Thinking; Product Development; Wood; b2c; refurbish;

    Abstract : Physical customer products have an environmental impact, such as greenhouse gas emissions, due to the use of virgin resources from cradle-to-grave, especially when the origin of the material is from fossil resources. This thesis aims to create a circular business model, by investigating the product ‘stroller’ and place it in a Product Service System, where the user subscribes to the Stroller Service System.

  4. 4. Thermoset biopolymer reinforced with carbon-nanotubes

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Morteza Esmaeili; [2019]
    Keywords : biopolymers; bio-composites; glycerol lactic acid; carbon nanotube; reinforcement; thermoset; dispersion;

    Abstract : Compared to conventional fibers, carbon nanotubes possess several significant properties, which make them as an excellent alternative reinforcement in multi-functional material industry. In this study, the possibility of dispersion of the multi-wall carbon nanotube (MWCNTs) in a thermoset bio-based resin (synthesized based on end-functionalized glycerol-lactic acid oligomers, GLA, at university of Borås) was investigated.
