The SpydIR® 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™ that improves detection of thin-wall PET, wet PET and full-sleeve labeled 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 and eliminates motion-related error and belt interference, increasing purity levels and hit rates.
