For over a century, we've looked underground for resources.
The next resource boom might be above ground.
Every year, the world generates over 62 million tonnes of e-waste, a figure projected to reach 82 million tonnes by 2030.
Hidden inside that waste are valuable materials:
- Gold
-Silver
-Copper
-Cobalt
-Rare earth elements
In fact, a tonne of discarded smartphones can contain up to 100 times more gold than a tonne of gold ore.
Yet less than 25% of global e-waste is formally collected and recycled.
The rest is landfilled, exported, stockpiled, or processed informally, taking valuable materials out of circulation.
This is why urban mining is gaining attention.
Companies are increasingly treating old electronics, batteries, and appliances not as waste, but as resource reservoirs.
As demand for critical minerals continues to rise, driven by EVs, batteries, and renewable energy technologies, the economics of recovering materials from existing products are becoming harder to ignore.
The circular economy is often framed as a waste challenge.
Urban mining reframes it as a resource opportunity.
The question is no longer whether these materials have value.
It's whether we can build the collection, recovery, and recycling systems needed to unlock it.
Could cities eventually become more valuable sources of critical materials than traditional mines?
