Extrusion International 3-2025

37 Extrusion International 3/2025 new standards, NGR's LSP process has successfully dem - onstrated its exceptional cleaning efficiency, setting a new benchmark in food-grade plastic recycling. Liquid State Polycondensation (LSP) process Unlike traditional solid state polycondensation (SSP), which requires prolonged high-temperature processing in a vacuum, the Liquid State Polycondensation (LSP) Process harnesses the faster reaction rates in the melt phase. This breakthrough approach significantly reduc - es energy consumption and processing time while deliv- ering high-quality results. The combination of high molecular agility in the liquid phase and the large surface area of the mate- rial strands ensures highly effective purification. The LSP process provides a consistent increase in intrinsic viscosity (IV) levels, with precise control and stability over extended operations. Rigorous challenge testing has proven its exceptional decontamination efficien- cy, meeting and exceeding the highest food safety standards. Exceptional results across all machine sizes NGR submitted its complete dossier for the LSP pro - cess in July 2023 and engaged with EFSA to address all questions raised during the rigorous evaluation. The Positive Scientific Opinion, published on January 13, 2025, affirms the high decontamination efficiency of the LSP Technology for all four machine sizes currently available: P:REACT 600, 1200, 2000, and 3000. Pioneering innovation and excellence in PET recycling “This recognition by EFSA is a testament to the inno - vative strength and technical expertise of our team,” said Josef Hochreiter, CEO of NGR. “Achieving the first positive Scientific Opinion under the new regulation underscores our commitment to advancing sustain- able, food-safe recycling technologies for a circular economy.” EFSA's Opinion serves as the foundation for final ap - proval by the European Commission, after which the LSP process will be officially assigned its RAN and listed in the public register.
