Phase IFoundation

Background

Overview

Addresses critical issues of environmental sustainability, resource security, public health, economic opportunities, and policy challenges in a rapidly digitizing economy.

E-waste, or electronic waste, refers to discarded electrical and electronic equipment. It is a rapidly growing waste stream globally, posing significant environmental and health hazards due to toxic components, but also representing a valuable secondary source of critical minerals through processes like urban mining, which recovers materials from products that have already served their purpose.
