Circular PP ProjectNEXTLOOPP™
A pioneering global initiative leading the development and adoption of high-purity food-grade recycled polypropylene.
Nextek is internationally recognised for pioneering food-grade recycling technologies and developing closed-loop recycling systems for polypropylene (PP), high-density polyethylene (HDPE), and polyethylene terephthalate (PET).
Our expertise spans material and packaging design, recycling process development, plant design and commissioning, materials testing, regulatory compliance, and commercial feasibility assessments.
Through collaborative initiatives such as NEXTLOOPP™ and NEXTLOOPP Americas, we are helping to accelerate the development and adoption of food-grade recycled polypropylene and circular packaging solutions worldwide.
Building on two decades of innovation, Nextek has developed COtooCLEAN®, an award-winning supercritical CO₂ decontamination technology designed to enable food-grade recycling of post-consumer flexible polyolefin packaging. Recognised by the Alliance to End Plastic Waste and now being demonstrated at scale with Coveris, COtooCLEAN represents a significant step towards closing the loop on flexible plastics.
Combining technical innovation, regulatory expertise, environmental assessment, and commercial strategy, Nextek helps organisations reduce reliance on virgin plastics, increase recycled content, and accelerate the transition to a low-carbon circular economy.
