Increasing IV values for recycled PET

Karin Regel, comPETence editorial team

At the K trade fair in Düsseldorf, three companies presented an alternative to SSP: a continuously operating reactor for the post-treatment of PET recyclable materials. The plant engineering company Aquafil Engineering GmbH from Berlin, Germany has named their reactor EverPET IV Lift, Gneuss Kunststofftechnik GmbH, Bad Oeynhausen, Germany now features JUMP in its product portfolio, and Next Generation Recyclingmaschinen GmbH based in Feldkirchen an der Donau, Austria calls their system P:REACT. Whereas the reactor designs, examined in greater detail below, vary slightly, they all fulfil the same purpose. In order be able to use recycled materials in more high-value applications, the IV value of PET waste materials from fibre, film or bottle production, as well as from post-consumer material must be increased in a targeted manner.
