Extrusion International 3-2022

35 Extrusion International 3/2022 Borealis, one of the world’s leading providers of advanced and circular polyolefin solutions and a European market leader in base chemicals and fertilizers; and the Grabher Group, a leading manufacturer of high-tech textiles, are accelerating plastics circularity in a partnership that safeguards human health while helping minimise waste. The key component of the high-quality, filtrating face masks produced by Grabher in Austria is made of fully recyclable meltblown polypropylene (PP) supplied by Borealis. To further drive circularity, Grabher has initiated a novel collect-and-recycle scheme for used face masks which turns them into new value-added products such as oil absorption fabrics. Another Life for Used FFP2 Face Masks Circular Economy P lastics circularity “made in Austria” through collabo- ration and innovation The Vorarlberg, Austria-based Grabher Group is a leading expert in nano-air and micro-liquid fltration and designs smart-textile systems for the manufacture of medical and healthcare products, among others. As the COVID-19 pandemic hit in early 2020, shortages of personal protective equipment (PPE) in Austria were im- minent. Grabher acted by becoming the frst Austrian company to establish a dedicated face mask assembly facility which included a state-of-the-art meltblown pro- duction system for the manufacture of high-quality face masks. These certifed masks, including FFP2 fltration respirators, medical masks, and washable community masks, are marketed by Vprotect, a 100%-owned mem- ber of the Grabher Group. One essential component of the Vprotect masks – the flter made of densely spaced micron-sized fbres – is made of meltblown PP supplied by Borealis, a material which itself is fully recyclable. Yet for obvious health reasons, even high-quality and more sustainable face masks are quickly disposed of. Far too many fnd their way into landflls or even natu - ral environments. To combat the problem of growing volumes of mask waste, Grabher again took action by creating a new return and collection system for used masks in order to recycle them into new, value-added products. The scheme, which is to be rolled out across Austria in the near future, features clearly marked col- lection boxes into which all types of face masks may be deposited. After sorting, washing, sterilising and drying, the material is used as fller material for cushion and oil absorption applications. Development is currently on- going to process the masks into granulate which may be turned into absorption fabrics using the meltblown process. These recycled fabrics may be used to absorb oil – for example due to a spill – or other liquids. “Our partnership with Grabher is the embodiment of EverMinds circular thinking,” claims VedranKujundzic, Bo- realis Vice President Commercial Performance Materials. “Using our fully recyclable meltblown PP to manufacture high-quality masks helps protect human health, and fnd - ing away to use themagain protects our planet. Together, Borealis and Grabher have taken yet another step to clos- ing the loop on plastics circularity bymaintaining our focus on sustainable solutions which beneft society.” “We are proud to have responded so quickly to the urgent need for PPE and FFP2 masks, in particular, at the start of the pandemic in Austria,” says Günter Grab- her, Managing Director of the Grabher Group. “In the meantime, we are gratifed that our collect-and-recycle initiative continues to attract numerous other partici- pants, including OMV, a major food retail group, and several large hospitals. In Borealis, we have found a reliable partner who shares our commitment to both innovation and sustainability, and we look forward to continued collaboration.” Borealis AG www.borealisgroup.com Grabher-Group GmbH www.grabher-group.company Thekey component of thehigh-quality, filtrating facemasks producedbyGrabher inAustria ismadeof fully recyclablemeltblown polypropylene (PP) suppliedbyBorealis (Photos:©Grabher)
