RECYCLING OF POLYCARBONATE FROM CDS TO EPOXY RESIN

Abstract

Waste management is the collection, transport, recovery and disposal of waste, including the supervision of such operations and aftercare of disposal sites according to European Union Directive on waste. E-waste is a popular, informal name for electronic products nearing the end of their useful life. E-wastes are considered dangerous, as certain components of some electronic products contain materials that are hazardous, depending on their condition and density. India is fifth largest producer of e-waste, discarding roughly 18.5 lakh tonnes of electronic waste each year. The amount of CDs and DVDs waste are about 4 lakh tonnes. The recycling of CDs and DVDs has been achieved using sodium hydroxide in THF. The obtained product was further used for the preparation of Epoxy resins. The epoxy resins have been widely used for coatings, electronic materials, adhesives, and matrices for fiberreinforced composites because of their outstanding mechanical properties, high adhesion strength, good heat resistance, and high electrical resistance. The epoxy resin made above is mixed with white cement to make the mold and for providing high strength to the mold even at high temperatures.
