   Abstract : Del A: Polyetylentereftalat fibrer I detta arbete presenteras olika metoder för att framställa monofilament av polyetylentereftalat (PET) (diameter: 30-50 µm) med en radiell gradient. Nyutvecklad Raman-spektroskopiteknik har använts för att kartlägga dessa inducerade radiella gradienter i t.ex. kristallinitet. READ MORE

4. 3. Recyclability by Design for Multilayer Plastic Flexible Packaging

   University essay from Lunds universitet/Förpackningslogistik

   Author : Sonika Singh; [2020]
   Keywords : Recyclability by design; multilayer flexible packaging; PE; PP; plastic recycling; circular plastic economy; Technology and Engineering;

   Abstract : Various recyclability by design (RBD) guidelines for multilayer plastic flexible packaging (MPFP) were assessed for consistency among parameter values. 9% consistency was observed, which is on the lower end of devised consistency scale. READ MORE

5. 4. A first look at some potentially plastic degrading enzymes

   University essay from Lunds universitet/Kemiska institutionen

   Author : Björn Pålsson; [2019]
   Keywords : PETase; PET; plastic degrading; enzyme; biotic degradation; plastic degrading organisms; biochemistry; biokemi; Biology and Life Sciences; Chemistry;

   Abstract : The many advantageous abilities of plastics have made them omnipresent in today’s society. However, the low cost of production, light weight, durability and insolubility in water combined with inadequate waste handling have led to a vast and increasing accumulation of plastics in nature, approximated to be over 6 300 million tons (Geyer, Jambeck and Law, 2017, ‘Production, use, and fate of all plastics ever made’, Science Advances, 3(7), pp. READ MORE

6. 5. Shape Distortion Analysis of Self-Reinforced Poly(ethylene terephthalate) Composites : The PETrifying reality!

   University essay from KTH/Lättkonstruktioner

   Author : Calle Eliasson; [2016]
   Keywords : ;

   Abstract : Composite components with a V-shaped geometry have been manufactured through compression moulding of fabrics based on self-reinforced poly(ethylene terephthalate). The fabrics were subjected to a set of predetermined degrees of stretching during manufacturing with the intent to investigate its effects on shape distortions in terms of spring-in and warping.
