E-Waste Recycling and PCB Metal Recovery CSR Proposal

E-waste to Wealth: Process Technology for Synthesis of Nano-particles from Printed Circuit Boards (PCBs)

Objective

• This proposal aims to establish a pilot plant-scale technology for environmentally friendly treatment of printed circuit boards (PCBs), employing a zero-discharge hydro metallurgical approach to extract metals and create value-added products. A distinctive feature is the production of nano-particles from the PCB metals, enhancing the overall value of the process.

Description

• The project aims to create an eco-friendly method for recovering metals from e-waste, presenting a business opportunity. The focus is PCBs comprising 30% metals and 70% non-metals. A lab-scale zero-discharge process for precious metal recovery has been developed, processing 100-250 grams of PCBs. The plan is to scale up to a 100 kg/batch pilot plant, understand scaling challenges, and eventually commercialize the technology for broader application.

Impact

• The project establishes a pilot plant for eco-friendly PCB nano-particle production, benefiting electronic goods manufacturers and recyclers while addressing global e-waste challenges sustainably.
