We’re pleased to announce that Catherine Walshe, Research Manager at ReVentas, will present at the AMI Flexible Packaging Conference in Vienna on 10 December 2025.
Her talk, titled “Dissolution Recycling for Currently Unrecycled Flexible Polyolefins for Food Contact Applications,” will explore how ReVentas’ dissolution process is opening new routes for recycling films and flexible plastics that have long been excluded from circular systems.
Flexible polyolefin packaging — from metallised snack films to high-ink or coated wraps — represents one of the biggest remaining challenges in plastic recycling. These materials are difficult to sort, often contaminated, and have traditionally been considered unrecyclable to food-grade standards. ReVentas’ process changes that.
By using dissolution recycling, we can separate polymers from inks, coatings, adhesives, and odorous residues without breaking polymer chains — returning the material to a virgin-like, high-purity state. This makes it possible to create recycled films suitable for food contact and other regulated applications, providing a true circular solution for flexible packaging.
Catherine’s presentation will highlight several recent case studies, demonstrating the recovery of clean polyethylene and polypropylene from complex waste streams including metallised, heavily printed, and multilayer films. She will also outline how the ReVentas process meets the stringent technical and regulatory standards required for food-grade use, based on ongoing collaboration with WRAP and analytical testing aligned to EFSA requirements.
About Catherine Walshe
Catherine holds a Master’s in Chemistry with French from Heriot-Watt University and a PhD in Chemistry from the University of Glasgow. Her career began in academic research on nanomaterials for gas capture, followed by experience in materials innovation at Unilever, where she worked on fast-moving consumer goods.
Since joining ReVentas, Catherine has become a core part of the team driving our technology from laboratory scale to industrial implementation. Now leading our research and process development teams, she brings deep technical insight and hands-on experience in scaling dissolution recycling to commercial operation.
At the Vienna event, Catherine looks forward to meeting fellow researchers, converters, and packaging specialists to discuss how dissolution recycling can help achieve the industry’s shared goals: reducing waste, lowering carbon emissions, and delivering truly circular materials for flexible packaging.
If you’re attending the AMI Flexible Packaging Conference, come and hear Catherine’s presentation to learn how ReVentas is redefining what’s possible in polymer circularity — from waste films to food-grade materials, built on purity by design. You can sign up to attend here.
