Abstract	Electronic waste (e-waste) and industrial waste represent both environmental burdens and untapped resource streams. Traditional disposal strategies face sustainability challenges due to hazardous components and accumulation rates. A promising alternative is the recovery and reuse of valuable elements to synthesize nanoparticles (NPs) with applications in catalysis, sensors, biomedicine, and energy devices. Eco-friendly alternatives with great selectivity that convert metal ions into NPsare provided by green recovery methods like biohydrometallurgy.This review comprehensively surveys methods for nanoparticle synthesis from e-waste and industrial by-products, characterizes the materials produced, discusses mechanisms, advantages, drawbacks, and identifies research gapsand discovers innovative methods to sustainable metal nanoparticle synthesis from WPCBs and waste Batteries.This review has significant implications since it identifies the synthesis of sustainable metal NPs from WPCBs as a key remedy for the environmental issues associated with e-waste, opening way for environmentally friendly recycling methods and provision of valuable materials for a variety of industrial uses.
Keywords	Green synthesis, E-waste, industrial waste, nanoparticles, recycling, materials recovery.
