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.
