Bühler and CarbonLite Unite to Meet Need for rPET with SORTEX Sorting Technology

Bühler supports plastic industry’s commitment to PET recycling initiatives.

London, United Kingdom, December 14, 2013 --( Bühler, a global leader in optical sorting, continues to strengthen its prominent position as a technology partner in plastics recycling, with the announcement that US-based CarbonLite, one of the world’s largest producers of food-grade recycled PET (rPET), has raised their output quality to near-perfect purity, following their installation of Bühler’s state-of-the-art SORTEX sorting technology.

Demand for rPET is outstripping supply, as consumers and brand owners alike continue to pursue ever more sustainable packaging options. To help meet this demand, Bühler has drawn on its many years of experience, to provide a solution that can sort colour and foreign material contaminants from post-consumer PET packaging, to help create a top quality end product.

Bühler has offered equipment dedicated to the production of PET since the 1970s and has long produced trusted optical sorting technology for the plastic industry.

With the advent of viable rPET for food grade packaging, Bühler has drawn on more than sixty years of successful optical sorting in the food industry to combine its sophisticated double-sided viewing capability, precise ejectors and Enhanced InGaAs technology, in a high capacity rPET solution. This delivers consistency, balance and performance, whilst maximising yield.

Luis Fernandez, Plastics Applications Specialist explained, “It is far more important to deliver a solution which meets requirements consistently, rather than exceed requirements inconsistently. Our experience prompts us to listen to the needs of individual plastics recyclers and produce a solution giving them the highest yield, compatible with consistent, balanced performance.”

CarbonLite selected Bühler technology for its ability to carry out simultaneous, multi-characteristic sorting of rPET flakes, including the removal of a wide range of foreign materials. Now, the company has the ability to sort incoming rPET flakes for colour, whilst simultaneously removing unwanted polymers such as PVC (polyvinyl Chloride), PE (polyethylene), PP (polypropylene), PA (polyamide) and PS (polystyrene), as well as aluminium and paper from the clear rPET.

The choice of sorting technology formed a vital part in CarbonLite’s investment last year, in a new 220,000 square feet bottle-to-bottle plastic recycling plant in Riverside, California, which now allows the company to recover over two billion used plastic PET bottles annually. The incoming post-consumer PET is processed into rPET pellets that can be manufactured into new plastic beverage bottles, to the exacting standards of food industry customers such as Pepsico and Nestlé.

“CarbonLite is delighted with the Bühler SORTEX installation, especially the technical and service support we received during the installation phase,” said Chairman Leon Farahnick. Thanks to the dedicated SORTEX sorting technology, his company has been able to simplify the stringent recycling process required to produce food grade rPET. In turn, this has reduced the CarbonLite plant’s energy consumption and carbon footprint.

“We’re committed to being the leading bottle-to-bottle recycler, while we preserve resources and reduce the carbon footprint from PET bottle production.” concluded Farahnick.

Bühler’s partnership with CarbonLite, turning post-consumer PET bottles into new PET bottles, supports the plastic packaging industry’s commitment to preserving virgin resources, reduce the number of PET bottles destined for landfill and harness the energy already expended in making the original PET bottles. The introduction of Bühler’s SORTEX technology for sorting plastics brings a long awaited solution that helps companies such as CarbonLite meet the demands of the food industry for high quality rPET. Nestlé has recently relaunched several of its water brands in new ReBorn bottles, made with fifty percent rPET and continues to support PET recycling initiatives. Yet more rPET is still needed. Bühler’s new solution for sorting plastics will go a long way to meeting this growing need.

Bühler is committed to further innovation to help extend the range of optical sorting application for plastics processing and to help recyclers achieve their goals. As plastic recyclers look to adopt more advanced, cost-effective and energy efficient processes, the demand for Bühler’s leading optical sorting solutions will continue to grow.
