NRT was the first to sort PVC from mixed plastics using X-ray technology in the early 1980s. Today, NRT continues to lead the industry in X-ray technology for a variety of applications. NRT has partnered with Spectramet® LLC to develop TruSort® with XRF™, an advanced X-ray florescent sorting system designed to separate materials at high throughput rates according to composition. The dry process uses patented imaging technology that electronically identifies material at the elemental atomic level.
