Bühler of the U.K. (U.S. office in Stockton, Calif.) has launched a new PET recycling solution, which is reportedly capable of improving yields by more than 30%. A strategic partnership with US-based National Recovery Technologies (NRT) allows the company to offer plastics recyclers a complete solution for plastic bottle and flake sorting.

The two-machine process solution delivers bottle-to-bottle grade rPET flakes, offering what the companies say is “superior color sorting, as well as sorting by chemical signatures, that can identify invisible and same-color polymers.” The result is high grade rPET flakes for bottle production, plus a significant increase in yield.

“Sustainability is increasingly vital in the food industry. Our new flake sorting technology enables our customers to recycle more plastic, more efficiently and to a higher grade,” says Bernhard Gabauer, segment development manager for Plastics at Bühler. “It is a perfect fit with Bühler’s environmental goal of a 30 percent reduction in energy, water, and resources in all core processes by 2020.”

As a result of the new offering, global OEM and PET recycler STF recently switched to Bühler’s new process solution and was able to increase its yield of bottle-to-bottle grade rPET flakes by more than 30%.

“We choose to use Bühler’s Sortex technology, as it is the best flake sorter on the market,” Josef Söllner, managing director at STF. “We undertook several industry trials to evaluate other technologies, but discovered that Bühler provided the best solution – first class machine results combined with impressive customer service."
