Urban Mining

Urban mining is the recovery of useful materials from products, buildings, infrastructure and waste already accumulated in human settlements. In e-waste, it converts discarded electrical and electronic equipment into secondary raw materials that can substitute partly for newly extracted resources.

How urban mining works

Urban mining treats discarded products as an above-ground stock of materials rather than as waste requiring disposal.

• Products are collected, sorted and dismantled into components and material fractions.
• Mechanical, chemical or metallurgical processes recover copper, aluminium, iron, precious metals, plastics and glass.
• Recovered materials are refined to the quality needed for reuse in manufacturing, thereby supporting a circular economy.

Importance for resource efficiency

Electronic products contain concentrated combinations of valuable and sometimes scarce materials. Their recovery can reduce dependence on primary mining and retain materials within the economy.

• It reduces the demand for virgin ores and the environmental disturbance associated with extraction and processing.
• It diverts recoverable materials from landfills and reduces losses from improper disposal.
• Domestic recovery can improve material security, but its feasibility depends on collection rates, product design, technology, scale and commodity prices.

Environmental safeguards and regulation

Urban mining is beneficial only when dismantling and recovery occur through environmentally sound systems. Unsafe informal practices, including open burning or crude chemical extraction, can release toxic substances and expose workers and nearby communities.

• The E-Waste (Management) Rules, 2022 apply the principle of extended producer responsibility to channel e-waste towards registered recycling.
• Effective urban mining requires traceable collection, safe handling, pollution control and proper disposal of residues that cannot be recovered.
• Design for durability, repair, disassembly and material identification improves future recovery rates.
