Using a mixed stream of feedstock, ranging from PET plastic packaging, polyester fibers 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
A full closed loop
DePoly set out to challenge itself by using PET and Polyester plastic waste from packaging and insulation. The DePoly technology produced a high-quality PTA used to produce recycled PET that was processed into bottles by injection stretch blow molding. 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.
