Introducing new technology in the field of plastics-recycling has always been the aim of Next Generation Recyclingmaschinen GmbH from Austria. The LSP process (Liquid State Polycondensation) for PET recycling combines the increasing of Intrinsic Viscosity (IV), excellent decontamination properties with low energy consumption.

PET is a material broadly used in food-packaging, such as for soft-drink-bottles or PET-Trays. In this field the global annual consumption reaches some 20 million tons. The PET fiber business is approximately double as big. Reasons enough to rethink the general approach of recycling the material and starting to take full advantage of the PET-properties by designing a new process.

Improving PET-properties in the Liquid State
As all polymers, also PET consists of polymerchains. The length of the chains determine the strength of the material and the viscosity (measured as IV-Value). Each step in processing the material (fiber spinning, film extrusion, injection molding, etc.), leads to “breaking” some of the chains apart, thereby causing the material strength being reduced and the viscosity of the
