Switzerland-based Bühler, in collaboration with US-based National Recovery Technologies (NRT), has developed a new polyethylene terephthalate (PET) recycling solution for plastic bottle and flake sorting.

Switzerland-based Bühler, in collaboration with US-based National Recovery Technologies (NRT), has developed a new polyethylene terephthalate (PET) recycling solution for plastic bottle and flake sorting.

Offering 30% more yielding than other recyclers, the new solution provides an innovative, two-machine process to the PET recyclers.

The recycler provides bottle-to-bottle grade rPET flakes and sorting by chemical signatures, which can recognise invisible and same-colour polymers.

"Our new flake sorting technology enables our customers to recycle more plastic, more efficiently and to a higher grade."

Furthermore, the new recycler combines NRT’s capability in bottle sorting and Bühler’s expertise in flake sorting.

Bühler plastics segment development manager Bernhard Gabauer said: “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.

“It is a perfect fit with Bühler’s environmental goal of a 30% reduction in energy, water, and resources in all core processes by 2020.”                           

As per a report from World Economic Forum and Ellen MacArthur Foundation, only 5% of waste plastic is estimated to be recycled effectively, posing huge ecological and other risks across the globe.

The report also noted that plastic production has increased 20-fold since 1964, to some 311 million tonnes in 2014.

The volume is expected to double in the next 20 years and quadruple by 2050.

Collecting and recycling PET plastic can help reduce millions of tonnes of waste annually.

Recycled plastics can be reused to produce several consumer products, as well as food and drink packaging.

Recently, Bühler provided its Sortex flake sorter to global PET recycler STF.
