cleaning performance. We believe it will soon become the widely accepted standard for bottle- to-bottle PET recycling.” NGR introduced LSP in 2011 under the product
name P:React. It says that while decontamination and IV improvement using SSP can require many hours, with the LSP process it takes only minutes. All impurities are removed from the PET melt while still in the liquid phase, “which guarantees simultaneous upgrading of the plastic and recycling to the highest standards of the brand owners”. At K2022, NGR promoted an updated version of P:React with some improved modules and which now features inline monitoring and control of the system and process. Other manufacturers are now also working on LSP solutions for PET processing, NGR notes, but it is well ahead, having already sold more than 50 systems in over 20 different countries. David Hehenberger, Product Manager PET at NGR, says: “The LSP technology is in the market since 2014 for the application of PET fibre recycling and produc- tion. In 2016 we had the first machines for PET sheet application, and in 2020 we developed the technology further to produce food grade pellets and also preforms.” The company has already

installed 10 systems for bottle-to-bottle PET recycling around the world. LSP works with higher temperature and higher vacuum than SSP, so contaminant molecules are more flexible and easier to remove, he says. “This is also a reason why the IV lift in the LSP-Reactor is done within minutes compared to hours (minimum 6 hours for food grade) in the SSP process.
