Sustainable valorization and conversion of e-waste plastics into value-added products

The rapid development of the electrical and electronic equip-ment industry has resulted in the generation of large amounts of waste electrical and electronic equipment plastic, causing an increasing environmental problem for their disposal. E-waste is considered as one of the fastest growing waste streams; however, it is a complex waste stream and comprises a mixture of hazardous heavy metals, plastics, and additives such as flame retardants and plasticizers. Although technolo-gies have been developed for recycling polymer fractions in e-waste, the high cost related to separation and sorting tech-niques associated with these methods usually leads to the landfilling or incineration of plastics. In this review, we give an account of the recent developments in the field of beneficiation of e-waste plastics. This includes studies on mechanical, chemical, and thermal recycling of e-waste plastics. Addition-ally, the use of e-waste plastics in composite applications as well as in construction sector has been elaborated.
