2. 1. Degradation of acrylonitrile butadiene rubber and fluoroelastomers in rapeseed biodiesel and hydrogenated vegetable oil

   Author : Shahin Akhlaghi; Ulf W. Gedde; Jean-Luc Gardette; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradation; Acrylonitrile butadiene rubber; Fluoroelastomers; Biodiesel; Hydrotreated vegetable oil; Cavitation; Bound rubber; Dehydrofluorination.; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. READ MORE

4. 2. Polymeric materials in nuclear power plants : Lifetime prediction, condition monitoring and simulation of ageing

   Author : Erik Linde; Ulf Gedde; Mikael Hedenqvist; Sue Burnay; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Nuclear power plants generate a significant part of the world’s electrical power consumption. However, many plants are nearing the end of their designed lifetime, and to extend the lifetime it is important to verify that every component can withstand the added service time. This includes polymeric materials, which become brittle with time. READ MORE

5. 3. Electronic Waste Plastics Characterisation and Recycling by Melt-processing

   Author : Erik Stenvall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; melt-blending; WEEE; ternary polymer blend; processing conditions; plastics recycling; composition analysis; e-waste;

   Abstract : Melt-processing of blended plastics from waste electrical and electronic equipment (WEEE) is a method to facilitate mechanical recycling, and this might improve the recycling conditions and increase the amounts of plastics being recycled. To ensure the quality of melt-blended plastic waste, it is essential to know the composition of the incoming material and then possibly improve the compatibility between the different polymer phases.

6. 4. Gamma irradiation in multi-cycle ABS recycling- effects on ABS properties and the recovery of antimony

   Author : Sandra Tostar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ABS; antimony; gamma irradiation; recycling; WEEE; plastics;

   Abstract : Electronic waste, also called waste electrical and electronic equipment (WEEE), is the fastest growing waste stream in Europe today. The fast exchange pace of mobile phones, televisions and computers creates an important need to develop recycling areas to take care of, reuse and recycle these materials. READ MORE

7. 5. Functional Properties and Morphology of Recycled Post-consumer WEEE Thermoplastic Blends
