N2 - The use of plastic materials is increasing worldwide because of their durability, cost-effectiveness, and light weight. This uncontrolled usage of plastic materials is creating severe disposal and environmental problems. This chapter includes recent and conventional practices for the recovery and recycling of plastic wastes. Brief classifications on the origin of plastic waste, such as thermoplastic, thermosetting, and elastomers, are specified. The sorting of plastic wastes plays a significant role in the overall performance of any recycling method. Various direct and indirect sorting methods are discussed along with their features and limitations. Recycling methods of plastic wastes are mainly classified as primary, secondary, tertiary, and quaternary. Detailed literature analysis including the advantages and technical challenges of each recycling method is discussed. A comprehensive investigation of the literature showed that new and innovative recycling approaches for plastic waste, particularly the scientific and technical inventions in tertiary recycling, present problems that impact their practicality in the industrial and manufacturing sectors. Currently, the recycling of highly contaminated plastic wastes from medical and e-waste are creating new challenges for the recovery and recycling sectors.
