RECYCLED COMPOUNDS | MATERIALS
three colour variants: grey, green and pink. Fairphone devices are known for their modular
design, which favours better repairability. Such a design requires materials with robust mechanical properties to enable repeated disassembly and repair. The glass-fibre-reinforced grade of the Makrolon PC portfolio offers a good solution for the heavily stressed centre frame of the Fairphone 4. Covestro also supports a mono-material ap- proach in each case for the use of polycarbonates in the housing and TPU plastics in the protective cover to facilitate recycling of the smartphones at the end of their useful life. Celanese and Mitsubishi Chemical Advanced
Materials (MCAM) are collaborating to develop mechanical recycling solutions for both post-indus- trial and post-consumer sources of polyoxymethyl- ene (POM, or polyacetal). The companies plan to work together to assess options to convert waste streams into marketable, end-product formulations so that Celanese can offer its customers sustainable options for scrap or end-of-life waste with assur- ances of closed loop material reuse. The recycled content option of the Celanese Hostaform/Celcon POM product will be marketed as POM ECO-R. MCAM would conduct the waste collection, separa- tion and processing, while Celanese would provide the formulation, product technology and production capability. Celanese expects to offer to existing and new customers its POM ECO-R solution with a recycled content offering of up to 30%. POM ECO-B, where the polymer itself is identical to its fossil- based twin but where the carbon feedstock is replaced with bio-based feedstock in a mass-bal- ance approach, is different from POM ECO-R in that
POM ECO-R would be derived from both post- industrial and post-consumer sources of POM to offer a recycled content solution.
