Recent Trends in Valorization of Non-metallic Ingredients of Waste Printed Circuit Board: A Review

  • Chapter
  • First Online:
Emerging Technologies for Waste Valorization and Environmental Protection

Abstract

Extraction and subsequent valorization of several non-metallic ingredients present in waste printed circuit boards (WPCBs) is a challenging area of research and development nowadays. Various technologies are being explored to procreate an environmentally viable as well as cost-effective recycling protocol concerning WPCB. From literature review, it can be deduced that several simple recycling techniques comprising of thermal, chemical, and hydrometallurgical methods can be employed to produce various value-added and precious materials from WPCB, which in turn reduces the generation of unusable solid wastes; thus mitigating waste management problems. This article provides an insight on various conventional and emerging technologies as well as challenges incurred in valorization of WPCB.
