Abstract


The threats to the environment and humans are increasing every day due to the use of modern plastics and their improper disposal approaches. Researchers pay more attention to reducing plastic waste through recycling so that it can be used as a raw material. In the recycling chain, grading or identifying different types of plastic is essential. For this, Lase Induced Breakdown Spectroscopy (LIBS) has been established. LIBS is an effective investigation tool that analyzes plastics in a qualitative and quantitative manner. Spectral analysis of different kinds of plastics is performed from the plasma emission obtained from LIBS. In this research work different types of plastic samples are identified using LIBS and classified using back propagation neural network algorithm (BPNN). The research aimed to attain a simple application to detect plastic polymers compared to existing approaches. To validate the better results proposed model performances are compared with existing kNN, SIMCA and ANN based classification models.
