Materials Recovery Facilities (MRFs)


NRT Optical Sorters are used in the largest and most advanced Materials Recovery Facilities (MRFs) in the world. As a component of Bulk Handling Systems’ (BHS) integrated solutions, NRT systems sort plastics, paper, metals, wood, aseptic containers and organics at industry-leading efficiency and purity rates. Custom sorts can be configured to suit requirements of changing market conditions, as valuable types and colored polymers can be identified and ejected with NRT’s advanced, flexible technology.

NRT installations are achieving industry-leading purity rates and offer real-time analytics on recovery and material composition. As the inventors of In-Flight Sorting® technology, we broke through again with transmissive detection, and continue to push the envelope with PET Boost™ technology. Our team of experts can design a solution customized to your operations. And with our culture of service and development, your solution can remain profitable throughout its life; NRT’s flexible equipment is able to adjust to market changes, and new upgrades can be applied remotely.

Near Infrared Spectrometry

SpydIR® -R An advanced infrared sorting system that separates numerous selected polymers from a mixed stream. Designed to identify and sort plastic film, fiber and remove them from mixed material streams. SpydIR® -R Equipment Page

SpydIR® -T An advanced infrared sorting system, using proprietary technology and fast highly sensitive algorithms to rapidly identify unique polymer “signatures” from their infrared spectra. Designed to perform separation of natural HDPE from Mixed Plastics streams, obtains a high rate of recovery, providing a clean PET product from polymer residue streams for return to main PET stream. Also used for the ejection of light blue PET from mixed plastics. SpydIR®-T Equipment Page


Visual Spectrometry & Color Line Scan Camera

ColorPlus™  An advanced image processing system that targets and sorts materials based on color analysis and sophisticated object recognition. Designed to separate color PET product from clear and light blue PET product, separate HDPE Natural from a HDPE container stream, and sort fiber streams according to color properties. ColorPlus™ Equipment Page 


Electromagnetic metal sensor

MetalDirector™ Uses advanced electromagnetic sensing technology integrated with the sorter’s ejection system for the removal of aluminum cans and other metal objects. Designed for installation into an accelerating conveyor of an optical sorter and integrated with the sorter’s ejection system for the removal of aluminum cans and other metal objects.  MetalDirector™ Equipment Page

Listed Equipment can be integrated at different levels within designed layouts. We are available to discuss the best solution to achieve industry best results for current and future challenges.
