Design and Development of Plastic Waste Sorting System using near Infrared Spectroscopy

Plastic is widely used material all over the world. Use of plastic creates waste which is must to sort. Plastic waste must be sorted so as to recycle into its various types. This article presents idea of using microcontroller based near infrared spectroscopy system to sort the type of plastic waste. Near infrared spectroscopy is a spectroscopic method that uses the near infrared region of the electromagnetic spectrum from about 700nm to 2500 nm. A prototype model has been developed which is able to control LED’S (Various wavelengths) and detectors. Index Terms - Detectors, LED’S, Near infrared spectroscopy, plastic sorting
