PRODUCTS PET products 29 PET planet insider Vol. 12 No. 12/11 www.petpla.net pet-recycling.com New S+S sorting systems S+S has developed solutions that separate contaminants from PET material flows and sorts them into unmixed fractions. Polymer separators with multi-spectral sensors are used to detect contaminants and plastic types. The fully-automatic systems separate unwanted plastic from the PET mate- rial by infrared absorption. S+S claims that its systems remove PVC contents or bioplastics such as PLA, which compromise recycled material quality and can make high-quality recycling impossible. S+S says that this is a valuable feature, given the increasing use of ‘bio bottles’, made of up to 100% vegetable raw materials, which cannot be distinguished from conventional PET bottles from the outside. www.sesotec.com Removing full-wrap labels before recycling Herbold Meckesheim has announced the commercial launch of its new label remover, which it claims is the first machine that can remove and separate PVC wraparound labels at the prewash stages of PET bottle recycling. It removes tightly-wrapped labels in a single step, early in the process and without the genera- tion of extra steam. Herbold Meckesheim says that the new machine helps to save money downstream in the recycling process, as cutting blades will stay sharp longer without the dulling effect of label remnants. Removal of labels and adhesives from bottles is achieved through friction between exchangeable rip-off elements bolted to the rotor and exchangeable pins fitted to stator elements. All rip-off elements and pins are made of wear-resistant steel. The chamber is designed to achieve even loads and dwell times as bottles are advanced by the rotor, and it has no spaces where bottles might pass through the machine without undergoing full frictional contact. The new machine is also able to separates bottles that are stuck together. Access for part replacement is through a hinged cover and additional service openings and the rotor’s dual self- aligning roller bearings are mounted within the housing, to minimise contamination. Anti-vibration mounting pads are standard. The label remover is available in 4,500 or 8,000kg/h capacities. www.herboldusa.net SPHERO® underwater pelletizers Beautiful things are formed underwater.
