“…In the past few decades, landfilling, combustion and informal processing activities [ 12 ], such as acid stripping and open burning have led to significant environmental pollution. Oloruntoba et al [ 13 ] assessed the status of polybrominated diphenyl ethers (PBDEs) contamination at e-waste dumpsites in Lagos, Nigeria. PBDE levels across the soil profile (0–45 cm depth) showed an increase in PBDE accumulation in the topsoil and migration into the sub-soil.…”

The rapid pace of innovations and the frequency of replacement of electrical and electronic equipment has made waste printed circuit boards (WPCB) one of the fastest growing waste streams. The frequency of replacement of equipment can be caused by a limited time of proper functioning and increasing malfunctions. Resource utilization of WPCBs have become some of the most profitable companies in the recycling industry. To facilitate WPCB recycling, several advanced technologies such as pyrometallurgy, hydrometallurgy and biometallurgy have been developed. Bioleaching uses naturally occurring microorganisms and their metabolic products to recover valuable metals, which is a promising technology due to its cost-effectiveness, environmental friendliness, and sustainability. However, there is sparse comprehensive research on WPCB bioleaching. Therefore, in this work, a short review was conducted from the perspective of potential microorganisms, bioleaching mechanisms and parameter optimization. Perspectives on future research directions are also discussed.
