Abstract

Cheap nonmetal fraction (epoxy resin, glass fiber, ceramics, etc.) accounts for 70% of e-waste/WPCB. It contains most of the hazardous brominated flame retardants. This chapter covers the direct and chemical recycling of NMF from WPCBs. Chemical recycling consists of combustion (smelting/incineration), pyrolysis, and depolymerization processes by using supercritical fluids, hydrogenolytic degradation, plasma treatment, hydrothermal methods, and gasification process. The purpose of thermal treatment of e-waste is elimination of plastic/epoxy resin components. Details of pyrolysis and hydrothermal depolymerization of WPCBs with different solvents are presented in this chapter.
