LABELLING PETplanet Insider Vol. 26 No. 09/25 www.petpla.net 22 Preprocessing PET bottles Compact prewasher Boretech’s compact Prewasher for PET bottle recycling integrates four key functions - de-labelling, separation, washing, and dewatering - into a single, modular unit. By consolidating these processes, operations are streamlined while enhancing both output quality and overall efficiency for recyclers, says the company. 99% label removal rate During the prewashing stage, a label removal rate of 99% and a label scrapping rate of 95% are achieved, ensuring that the final rPET meets strict FDA and EFSA standards for label residue. In the multi-stream separation process, caps, rings, labels and impurities are separated in one integrated process, with online collection and packaging, minimising auxiliary material loss. Compared to traditional systems, the design is claimed to be both sustainable and space-saving. It reduces the footprint by 58% (96m²) and cuts total power consumption by 46% (63 kW), according to Boretech. Additionally, the single-unit modular system eliminates multiple transfer steps, incorporates washing into de-labelling, reduces investment costs by 67%, and simplifies maintenance, the company summarises. A clean-operation structure keeps the workspace tidy, while patented blades ensure less than 1% material loss and a service life of up to 8,000 t, even when handling hard impurities. A built-in, self-cleaning negative pressure cyclone prevents clogs, ensuring uninterrupted production and greater profitability for recyclers. www.bo-re-tech.com LABELLING .PSF UIBO KVTU 7*4*0/ */41&$5*0/ 7JTJU VT )BMM $ #PPUI $ 7JTJU VT )BMM #PPUI "
