Our products

Product category: Separating and sorting systems for waste

SpydIR® bottle sorter

The SpydIR® range, available in two variants for transmissive or reflective light, is an advanced infrared sorting system that separates numerous selected polymers from a mixed stream. It uses proprietary technology and fast, highly sensitive algorithms to rapidly identify unique polymer ‘signatures’ from their infrared spectra.

SpydIR® is the only technology that uses PET Boost™ (patent pending) that improves detection of thin wall PET, wet PET and full sleeve labelled PET.

While other optical sorters detect material over the belt and eject some time later, NRT offers In-Flight Sorting®, which detects and ejects material in flight. In-Flight Sorting® enables the use of transmissive detection for the highest detection strength available and eliminates motion-related error and belt interference, increasing purity levels and hit rates.

ColorPlus™ Imaging System

The NRT ColorPlus™ Imaging System is an advanced image processing sorting system designed to target and sort materials based on precision colour analysis and sophisticated form factor recognition.

The ColorPlus™ Imaging System utilises a network of powerful high-speed processors and intelligent recognition algorithms to analyse colour, transparency, opacity, and physical form factors including opaque analysis and label recognition for errorless object targeting. 
NRT has upgraded its ColorPlus™ technology, enabling the equipment to detect up to 50 million pixels-per-second. High resolution sorting, combined with NRT’s In-Flight Sorting® technology, allows the ColorPlus™ to distinguish the correct bottle colour or opaqueness (such as clear PET) when only 1% of the material is visible.

SORTEX A ColorVisionTM

Available in four sizes, the SORTEX A range provides plastic recyclers with dedicated customized options to handle the most unique and challenging sorting requirements. Showcasing Bühler innovation with new advanced inspection and lighting systems, tiered chute and Label Reduction Kit, this  state-of-the-art technology provides the ultimate PET and HDPE flake sorting solution, with the highest throughput in the industry.

The SORTEX A uses rear and front ended, high-definition color cameras and broadband LED lighting to detect contaminants with up to half the pixel size of other industry solutions. Bühler’s proprietary technologies ensures the accurate removal of foreign materials in the smallest of PET and HDPE flakes for higher recovery and increased profitability. The tiered chute provides exceptional separation of PET and HDPE flakes for easier targeting while the unique SmartEject™ system sits directly under the chute for the most accurate ejection of defective flakes and foreign materials for industry-leading reject concentration with next to no loss of good product.

Process engineered with flexibility to handle small to large capacities, the SORTEX A is available in one to five module versions, in three different frame sizes.

Product category: Separating and sorting systems for waste


Bühler’s brand-new optical sorter, exclusively designed for plastic recyclers, is equipped with the latest advancements in polymer sorting to remove non-PET flakes from clear, blue, green and jazz applications with unrivalled precision and ease.

Featuring ground-breaking PolyVision™ technology which uses a unique combination of transparent and reflective sorting simultaneously to identify invisible and same-colour polymer contaminants by their unique chemical signature, combined with a state-of-the art sided detection system and patent pending lighting for industry-leading removal of polymer contaminants such as PVC, PP and PE with minimal loss of valuable flakes.

The SORTEX E PolyVision™ is one of the most flexible optical sorters available in the industry. Designed to be paired with the SORTEX A ColorVision™ for best all-round colour, polymer, metal and foreign material removal or to be used as a 3-in-1 sorter targeting all defects depending on the application and sorting requirements.

• Removes same-colour PVC, PP and PE flakes
• Reduces same-colour PS, PA, POM and Silicon flakes
• Delivers higher grade PET flakes consistently
• Provides greater flexibility, recovery and profitability

Company details

Bühler is a leading global supplier of optical sorting solutions to various industries and has been at the forefront of optical sorting technology for almost 70 years. 

 With a commitment to substantial investment in research and development, Bühler has developed state-of-the-art technology that allows recyclers to achieve the ultimate yield, maximising their productivity and profitability. 

SORTEX advanced optical sorting technology focuses on capacity, speed and accuracy to obtain near-pure resin streams in many recycling industries including the packaging, construction, electronic/electrical (WEEE), End-of-life vehicle (ELV)) and petrochemical sectors; providing solutions to the most difficult and challenging applications. 

 At the forefront of PET and HDPE recycling. 
Bühler is also renowned worldwide for supplying industry leading optical sorting solutions for PET and HDPE recyclers that maximise not only their processing capacities but also the recovery and purity of recycled flakes.

With the most flexible and versatile optical sorting portfolio, Bühler can supply a truly dedicated one-stop optical sorting solution that targets all major PET and HDPE recycling concerns. From colour, polymer, metal and foreign material removal, processors can be confident of the highest grade recycled flakes – every time.

Bühler and NRT
Bühler has also joined forces with US based bottle sorting company, NRT, to provide PET and HDPE recyclers with a complete optical sorting solution from bottle to flake. This innovative alliance brings together over 100 years of optical sorting know-how to the recycling industry and the best of both flake and bottle sorting technologies.
