Overview

The SpydIR-T 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.

This advanced technology is available in two models: the SpydIR-R, which uses reflective

detection, and the SpydIR-T, which utilizes transmissive detection. While other companies

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, and

eliminates motion-related error and belt interference, increasing purity levels and hit rates.

The spectrometer array across the width of the belt greatly increases accuracy

compared to rotating mirrors which are prone to error.
