In response to the global challenge posed by mounting plastic waste, Technological University of the Shannon (TUS)<\/a> is leading cutting-edge research to develop food-safe and industrial-grade sustainable polymer alternatives. Led by Vice President of Research, Development and Innovation Dr Liam Brown, TUS\u2019s seven research institutes are working collaboratively to leverage scientific expertise, strategic partnerships and a commitment to environmental responsibility to drive change.<\/p>\n With the newly amended European Packaging & Packaging Waste Directive mandating that a minimum of 55% of all plastic packaging be sustainable by 2030, TUS has intensified its efforts to provide companies with alternatives under the leadership of Dr Margaret Brennan-Fournet, a renowned materials scientist based at TUS\u2019s LIFE Health and Wellbeing Biosciences Research Institute in Athlone.<\/p>\n Dr Brennan-Fournet and her team are spearheading initiatives to innovate low-carbon industrial-grade plastic packaging solutions through the cross-institute Centre for Polymer Sustainability. These innovations operate within circular \u2018make, unmake and remake\u2019 lifecycles, ensuring sustainability and regenerative processes akin to natural ecosystems. By pursuing a high-risk, high-gain visionary strategy to cultivate the \u2018make-unmake-remake\u2019 strategy, the process has the potential for full commercialisation applications ready for industry-grade production.<\/p>\n Key among TUS\u2019s initiatives is the EcoPlastiC project<\/a>, funded under the highly competitive European Innovation Council. Working closely with consumers, industry, international partners and policymakers, TUS\u2019s EcoPlastiC project has developed technologies to facilitate the full decoupling of polluting plastics consumption from the current extraction of fossil fuels and instead enable entry into permanent regenerative loops. Applying advanced waste stream fermentation and processing, biodegradable circular plastics and plastic solutions<\/a> with high performance for the sustainable food packaging sector are being developed as direct alternatives to current polluting petroleum-based plastics.<\/p>\n Examples include:<\/p>\n TUS\u2019s EcoPlastiC prototypes are designed to operate within fully circular life cycles and can be readily \u2018unmade\u2019 using new in-house depolymerisation technology, followed by \u2018remaking\u2019 within continuous loops. These and further industry-grade products are now available for development with collaborative enterprise partners.<\/p>\n Further bolstering sustainability efforts is TUS\u2019s \u20ac2.9m PerPETual project, supported by Enterprise Ireland\u2019s Disruptive Technologies Fund. Post-consumer biopolymer and petro-polyesters can now be \u2018unmade\u2019 through a new disruptive proprietary low-cost, high-yield green reactive extrusion depolymerisation (Rex) processing system.<\/p>\n The Rex process delivers circularity for the everyday polymer material Polyethylene Terephthalate (PET) with continuous \u2018virgin-to-virgin loop\u2019 recycling processes suitable for all grades of PET, spanning pristine grades used in bottles to low-grade pots, tubs and trays with no loss of polymer performance.<\/p>\n This has the potential to make a significant contribution towards halting finite resource depletion, landfilling, and incineration of waste plastics instead of converting them into valuable resources and demonstrating the implementation of a circular plastics model.<\/p>\n The Rex process can be readily integrated within existing manufacturing lines to depolymerise post-consumer PET waste. Producing Purified Terephthalic Acid (PTA) and Ethylene Glycol (EG), these PET precursor monomers can be readily repolymerized as virgin PET, making it available for use again in food packaging and beyond.<\/p>\n Expansion of the Rex technology makes it effective for mixed PET streams and other petro- and bio-polyesters. This unlocks waste plastic resources, making them available as feedstocks for depolymerisation or fermentation for the manufacturing of regeneratable packaging that operates within cyclical loops. TUS is actively seeking to work with companies requiring circular lifecycles for pure and mixed PET-based streams.<\/p>\n Regenerative manufacturing not only lowers the ecological footprint of production processes but also seeks to restore and rejuvenate. Within plastic processing, this can be achieved using conventional chemical repolymerisation in the case of pure monomer streams such as PET or via fermentation and biopolymer processing (remake) in the case of mixed feedstocks. The sustainable polymers produced are fully compatible with conventional and state-of-the-art plastic processing and manufacturing techniques, including multilayer film co-extrusion, blown film extrusion, and injection moulding for the fabrication of commercial products for the food packaging sector and broader plastics sectors.<\/p>\n To increase the adoption and uptake of sustainable technologies, TUS is actively engaging with plastic value chain industries, empowering companies to achieve circularity for their products and processes.<\/p>\nMake: Indefinitely recyclable, sustainable plastic products manufacturing<\/h3>\n
