During the past 30 years, NRT has developed dozens of technologies and advances for use in Near Infrared (NIR), X-ray and Color Line-Scan Camera Sorting applications and systems. Today, NRT owns or is the exclusive licensee of 29 U.S. patents and five foreign patents covering these disciplines, with others pending. Utilizing top-of-the-line technology and components, our equipment features scan rates of up to 10,000 scans-per-second and boasts industry leading capture rates.

Optical Sorting Technology

Best-in-class technology has been NRT’s core competency since inception. Throughout the years, NRT has been supported in the development of these new technologies by the U.S. Environmental Protection Agency and the U.S. Department of Energy, where the company pioneered technology that is used throughout the world.

Today, NRT has the manufacturing expertise to apply its highly sophisticated technology for 24/7 operation in rugged applications such as construction and demolition recycling, material recovery facilities and mineral sorting environments.  Recently NRT developed the world’s fastest X-ray fluorescence (XRF) sensing system for identifying and sorting shredded scrap metal and nonferrous alloys on fast moving conveying systems in sub-second time frames. Our In-Flight Sorting technology and full array of spectrometers provides industry leading purity and hit rates.
