==Near Infra-Red/[[NIR Optical Sorting]] in the Plastics Recycling Process== | |||
NIR sorting is widely used to separate [[Waste|waste]] plastic streams by using automated equipment that sorts [[Plastic|plastic]] [[Recycling|recycling]] by NIR signature via transmission or reflection. Automatic sorters interface NIR sensing with air nozzles to sort [[Plastic|plastic]] items of various resin compounds. The sensors are positioned above the high-speed conveyor and detect the unique wavelength signature of the desired polymers which subsequently get directed by air jets to their specific [[Waste|waste]] streams. Contaminants become the [[Waste|waste]] output or are directed for further processing<ref>[https://plasticsrecycling.org/images/Design-Guidance-Tests/APR-RES-SORT-2-NIR-sorting-resource.pdf Near Infra-Red (NIR) Sorting in the Plastics Recycling Process]</ref>. | |||
