Urban mining
Topic: Environment and Sustainable Development · NCERT: Beyond NCERT
Meaning
Urban mining means recovering valuable materials, mainly metals, from e-waste and other waste produced in cities. Discarded phones, laptops and batteries contain metals that can be taken out and used again. This reduces the need to dig new mines. It also stops toxins such as lead and mercury from leaking into soil and water when these products are dumped. Urban mining is a key part of the circular economy, which keeps materials in use instead of throwing them away.
Example
India is among the largest generators of e-waste. Under the E-Waste Management Rules 2022, producers must arrange for their products to be collected and recycled at end of life. Recyclers then recover copper, gold and other metals from old circuit boards. This is urban mining in practice.
Don't confuse with
- Recycling: this is the broad idea of reusing any waste as an input, such as turning waste paper into new paper. Urban mining is recycling aimed specifically at recovering valuable materials, mostly metals, from urban waste.
