7 NEWS PETplanet Insider Vol. 26 CREATING FUTURE STANDARDS Japan’s leading Aseptic PET Filling System Provider. Our website Our solution high quality reliable technology safe & secure DePoly and PTI partner to create closed loop recycled PET bottle DePoly, the Swiss CleanTech company which is specialised in advanced recycling of PET/polyester plastics, announced their collaboration with PTI (Plastic Technologies Inc) a leader in sustainable plastic packaging design and development, to create a closed loop recycled PET bottle. Using a mixed stream of feedstock, ranging from PET plastic packaging, polyester fibres and industrial waste, DePoly’s technology has broken down the PET and polyester back to its raw monomers, Purified Terephthalic Acid (PTA). From this virgin-grade quality PTA, PET pellets were produced. Finally, these PET pellets were blown into recycled PET bottles using PTI’s 40 years of expertise and technology. DePoly set out to challenge itself by using PET and polyester plastic waste from packaging and insulation. The DePoly technology produced a high-qual i ty PTA used to produce rPET that was processed into bottles by injection stretch blow moulding. This project demonstrates the strengths of bringing together the technical robustness of DePoly and PTI’s extensive expertise in plastic packaging processing and manufacturing. Both companies worked together to demonstrate a closed loop solution for plastic recycling into high grade bottles. Blowing a PET bottle is generally one of the more challenging end products to produce, highlighting the experience of PTI and maturity of DePoly’s technology, capable of bringing a universal approach to PET & Polyester recycling. Making bottles from varied PET & polyester waste DePoly’s uncompromising take on quality has been at the heart of this project. Not only did they succeed in producing a recycled PET bottle, but they did so by taking a broad spectrum of feedstock with the final product being a recycled PET bottle, one of the most difficult products to create. From a challenge point of view, this ticks off all the boxes and further demonstrates that DePoly’s technology is versatile and adaptable, enabling the company to pave the way for a new standard in the industry. In parallel to the bottle sampling, the conclusion of a preliminary screening analysis of non-intentionally added substances (NIAS) in DePoly rPET material is showing that the tested sample complies with the overall and specific migration requirements for the PET typical substances in contact with all types of food at any long-term storage at room temperature and below, including hot fill. www.depoly.co www.plastictechnologies.com
