Plastics

Types and colored polymers can easily be identified with NRT’s advanced technology. Custom sorts can be configured and/or easily changed to suit the requirements of changing market conditions. NRT has proven installations that are achieving leading purity rates sorting bottles, flakes and granulates.

In the early stages of automated recycling, NRT’s founders identified a need in the plastics industry for processors to remove contaminants from their commodity streams. The solution NRT developed and patented in the early 1980’s was the world’s first optical sorter, applied to sort PVC from mixed plastics. Today NRT continues its history of innovation, developing new and improved ways to clean and sort PET and other plastics for the fiber and plastic bottle industries. 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 unique to your operations. And with our culture of service and development, your solution can remain pro table throughout its life; NRT’s flexible equipment is able adjust to market changes, and new upgrades can be applied remotely. Throughout the world, NRT solutions are currently removing contaminates with near-zero product loss while providing operators real-time analytics. Our customers are leading the industry in purity rates and uptime, and have peace of mind knowing that we’ve got their backs.

SORTING TECHNOLOGY

NIR

Near Infrared Spectrometry

SpydIR®-R Uses reflective technology to select film, fiber, PET, HDPE or Mixed Plastics. Removes polymer contaminants from a PET container stream with high accuracy including PVC, PS, PETG, PLA, and PC, PE, PP and other polymer contaminants in any combination. SpydIR® -R Equipment Page

SpydIR®-T Uses transmissive technology and fast, highly sensitive algorithms to rapidly identify unique polymer “signatures” from their infrared spectra. Separates HDPE -N from either HDPE and/or mixed plastics streams; identifies PET, including thin-walled PET and wrapped PET.  SpydIR® -T Equipment Page

Online Analyzer™ Monitors PVC content and low melt content data which are measured and displayed on a industrialized computer screen. Designed to retain historical data such as contamination levels, with capabilities to send alarms to process PLC for contaminated flake diversion.

VIS & RGB

Visual Spectrometry & Color Line Scan Camera

ColorPlus™ An advanced image processing system that detects and sorts materials based on color analysis and sophisticated object recognition. Ejects color PET from clear PET; ejects HDPE Natural from a HDPE container stream; ejects full or partial labeled bottles. ColorPlus™ Equipment Page 

EM

Electromagnetic metal sensor

MetalDirector™ Uses advanced electromagnetic sensing technology integrated with the sorter’s ejection system for the removal of aluminum and other metal objects. Designed as an addition to an existing NRT optical sorter.  MetalDirector™ Equipment Page

MetalDirector™ Flake Uses advanced electromagnetic sensing technology to remove virtually all ferrous and non-ferrous contaminates from plastic flake commodities. Designed to clean metal flakes out of a PET flake stream down to sizes as small as 1 mm. MetalDirector™ Flake Equipment Page
