Plastic classification with infrared radiation

Most of the things around us contain plastic in their composition, which makes plastic one of the most widespread materials on earth, and as a result of its short life, this makes the recycling process necessary and important. The recycling process requires a highly accurate sorting process, and it is not logical that the separation process is done manually, which led to the development of automatic methods of separation. This project focuses on the development of an automated system that utilizes near-infrared reflectance spectroscopy to identify and separate different types of plastic. The system employs the principles of near-infrared radiation to analyze the reflective properties of plastic samples.using a conveyer belt, the plastic piece is placed on it and separated based on a reading that is taken and sorted into containers using an air pump. 3
