This document discusses electronic waste (e-waste) management for ecological balance. It notes that e-waste is one of the fastest growing segments of waste streams due to rapid technology changes and planned obsolescence. Approximately 50 million tons of e-waste is produced annually, which can harm the environment and human health if improperly disposed of, as it contains toxic materials such as lead, mercury, and cadmium. The document recommends recycling and reuse as environmentally preferable solutions to reduce pollution and resource consumption from manufacturing new products.
