MATERIAL / RECYCLING 21 PET planet insider Vol. 15 Short cycle times, high shot-to-shot quality, low energy consumption and maximum flexibility. The new XFORM 300 with its unique 6-position post-mold cooling system boosts your output performance for the widest range of preforms. Cooling preforms faster and better, the 96-cavity platform is ideal for large runs and quick mold changes. And it lets you run any mold you want, old or new, OEM-built or not, in total freedom . From ultra-thin walled (with proprietary XMould™ technology) to wide mouth. XFORM 300 , low transformation cost, high value.

The new XFORM 300 IMAGINE THE LOWEST TRANSFORMATION COST. IN TOTAL FREEDOM. On delivery the bottles are exam- ined and non-PET components are sorted out manually. Having estab- lished that only PET bottles are pre- sent in the process these are crushed in a mill to form flakes. The flakes now go through not only a dry but also a wet cleaning process. Contaminants and dirt are removed using a chemical treatment. The PET flakes can now be sepa- rated from one another on the basis of differences in their spe- cific weight and then dried. In the United Resource Recovery Corporation (URRC) process the flakes again undergo thorough gentle cleaning. Since the flakes are required to conform to very high food safety standards, it is important that any flavouring agents are removed. For this reason the top layer of the flakes is removed. The manufacture of the recyclate in the recoStar PET granulating line is carried out in the following sequence. The washed flakes are first of all dried, then melted, filtered using a fine filter, pressed through a nozzle plate and finally cooled under water and cut into spheri- cal pellets. After this, the granulate is crystallised and subjected to in-depth cleaning using Solid State Polycondensation (SSP). The mechanical characteristics are being improved, and today the recycled PET granulate has to all intents and purposes the character- istics of new material. The combined process- ing of both these forms of recyclate in the future will bring together the advantages of maximum purity and colour quality with optimum processing conditions – in terms of a further increase in the use of recyclate in the PET beverage bottle. The PET recyclate is packed into big bags and added at the premises of the preform and bottle producers during the manufacture of new PET bottles. The proportion of recycled PET is on average 30%, depending on the size and shape of the bottles. It can also be more. PET to PET in Müllendorf work round the clock in four shifts. Production is shut down on one day a month only to enable clean- ing and maintenance works to be car- ried out. The time from delivery of the bales consisting of collected PET bot- tles to delivery of the PET flakes in big bags is a mere seven to eight hours. www.pet2pet.at PET to PET Recycling Österreich GmbH plant
