Carpet sorting technology has undergone rapid development in the last year, and is currently a mature and robust system. The introduction of FT-NIR spectroscopic equipment and data analysis techniques has provided significant improvements over more traditional spectroscopic methods in terms of speed, accuracy, and reproducibility of results. These improvements owe a great deal to the cooperative nature of the companies that have provided invaluable feedback during the development process. The future of such systems seems very promising, with several potential applications, such as quantitative analysis of recycled carpet fibers, showing early fruit. Future enhancements to the system, and expansion into related areas such as quantitative analysis of finished products will stand to benefit from a continued spirit of cooperation and communication within the industry.
