materials in all new mobile products by 2025.” Fairphone is a Netherlands-based brand that was set up on ethical lines, so its phones, for example, have replaceable modules for main components in order to increase the product’s lifetime. It also has a focus on sustainable materials and is using an increasing amount of recycled plastics. Covestro says fully and partly recycled thermoplastic polyurethanes (TPU) are used in the protective case of the Fairphone 3 and its succes- sor, the Fairphone 4, and partly recycled polycar- bonates are additionally used in the newer device. Glass fibre-reinforced grades of the Covestro’s
Makrolon PCR PC portfolio offer a good solution for the heavily stressed centre frame of the Fair- phone 4, says the materials company. “The in- creased stiffness and impact resistance are in line with Fairphone’s modular design approach. Covestro thus also supports a mono-material approach in each case for the use of polycarbon- ates in the housing and TPU plastics in the protec- tive cover to facilitate recycling of the smartphones at the end of their useful life,” says Covestro. Online electricals retailer,AO, which runs a
fridge recycling operation in Telford, UK, says it is expanding the materials it is supplying to its customer Volution, a ventilation technology group. AO has supplied Volution with recycled high impact polystyrene (HIPS) from recycled fridges, collected from customers’ homes, and is widening its supply to also include recycled acrylonitrile butadiene styrene (ABS). The rABS will be used to produce a range of parts including the fan chassis of the ventilation and components, with the HIPS continuing in the manufacture of the ducting
accessories (also see feature in Plastics Recycling World July-August 2021 issue). Lee Nurse, Business Development Director at
Volution Group, says: “We are really excited to have worked with AO to help us get this new source of recycled material into our facilities. Our procure- ment teams continue to drive our ambition for 90% of the plastic within our facilities to come from recycled sources, and even with the complexities of the global supply chain situation, we are still making great progress towards that goal. Increasingly, manufacturers are working in R&D
projects with industry partners to validate the use of recycled plastics in their products. Bosch and Bosch-Siemens-Hausgeräte have been involved in a project with Fraunhofer Institute for Struc- tural Durability and System Reliability (LBF) in Germany to compare the performance of recycled plastics and virgin material in a demanding application, the base frame of dishwashers. The base, which weighs around 2 kg, forms the basic

ERF 1000
ETTLINGER continuous melt filters have been processing contaminated polyolefines, poly- styrenes, PET and PA since 2004. Now, with the ERF 1000 you can achieve up to 10 t/hr of e.g. polyolefines with the lowest melt loss in the industry. With rigid-screen, continuous filtration options down to 60 micron, ETTLINGER ERF is the new standard in melt filtration.
