Using a mixedstream of feedstock, ranging from PET plastic packaging, polyester fibers andindustrial waste, DePoly’s technology has broken down the PET and polyesterback to its raw monomers, Purified Terephthalic Acid (PTA).
From this virgin-grade quality PTA, PET pellets wereproduced. Finally, these PET pellets were blown into recycled PET bottles usingPTI’s 40 years of expertise and technology.
DePoly set out to challenge itself by using PET andPolyester plastic waste from packaging and insulation. The DePoly technologyproduced a high-quality PTA used to produce recycled PET that was processedinto bottles by injection stretch blow molding.
This project demonstrates thestrengths of bringing together the technical robustness of DePoly and PTI’sextensive expertise in plastic packaging processing and manufacturing. Bothcompanies worked together to demonstrate a closed loop solution for plastic recyclinginto high grade bottles.
Blowing a PET bottle is generally one of the morechallenging end products to produce, highlighting the experience of PTI andmaturity of DePoly’s technology, capable of bringing a universal approach toPET & Polyester recycling.
DePoly’s uncompromising take on quality has been at theheart of this project. Not only did they succeed in producing a recycled PETbottle, but they did so by taking a broad spectrum of feedstock with the finalproduct being a recycled PET bottle, one of the most difficult products tocreate.
From a challenge point of view, this ticks off all the boxes andfurther 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 apreliminary screening analysis of non-intentionally added substances (NIAS) inDePoly rPET materialis showing that the tested sample complies with the overalland specific migration requirements for the PET typical substances in contactwith all typesof food at any long-term storage at room temperature and below,including hotfill.
“For this project we really wanted to challengeourselves, taking a mixture of different PET and polyester containing wastestreams that are blended and have different additives. Being able to hold thisbottle in my hands, is a testament to DePoly’s and PTI’s ingenuity andexpertise!” Said Dr. Gaetano Dedual, Senior Business Development Manager ofDePoly.
