Copper has become one of the defining materials of the digital and energy transition. It runs through telecommunications networks, data centres, power grids, renewable energy infrastructure and transport systems. As connectivity expands and electrification accelerates, demand is rising with it. The conventional response is straightforward: find more copper and mine it.
Across the world, governments and industry are looking again at domestic mineral resources, new mining projects and ways to secure supplies of materials increasingly considered strategically important.
But there is another source of copper much closer to home. It is already sitting beneath our streets, inside exchanges, along our railways and across telecommunications, power and utility networks, locked within infrastructure that has reached the end of its operational life.
The question is whether we are treating it like waste or recognising it for what it is: a valuable resource.
The growing pressure on copper
The infrastructure being built today is extraordinarily material-intensive. Fibre and mobile networks continue to expand. Data centre capacity is growing to support cloud computing and AI. Electricity networks need significant investment to accommodate renewable generation, electric vehicles and rising power demand. All of this puts pressure on copper supply.
New mines will inevitably form part of the answer. But mining is neither quick nor simple. Identifying a viable deposit is only the beginning. Planning, environmental assessment, permitting, financing, infrastructure development and construction can mean many years pass before the first commercially usable copper is produced. Once extraction begins, the amount of useful metal recovered can represent only a fraction of the material moved and processed. That makes the copper already circulating through our economy increasingly difficult to ignore.
There is a mine within our existing infrastructure
Decades of infrastructure development have created substantial reserves of valuable material. Copper remains embedded across telecommunications networks, rail infrastructure, power and utility networks, data centres and other technology estates, often long after the equipment or infrastructure it supports has reached the end of its operational life.
As organisations modernise networks, replace ageing technology, consolidate sites and decommission redundant infrastructure, more of this material becomes available for recovery. In telecommunications, the transition from copper to fibre and the consolidation of legacy exchanges provide a particularly clear example of the opportunity.
This is the principle behind urban mining and asset recovery: treating existing infrastructure as a source of materials that can be recovered and returned to productive use.
Unlike a conventional mine, the material has already been extracted from the ground. The infrastructure already exists and, in many cases, its location and composition can be identified before recovery begins. The challenge is accessing it safely, efficiently and commercially.
The business case for urban mining
Recovering copper should not be viewed simply as a recycling exercise at the end of a project. Done strategically, asset recovery can become part of the business case for network transformation itself.
When a legacy site or network is decommissioned, different assets require different routes. Some equipment may still have operational value and can be redeployed internally. Other technology can be refurbished and resold into the secondary market. Components may be harvested for spares. Only when further use is no longer viable should materials move into appropriate recycling streams.
Copper and other metals recovered from cables, power infrastructure and obsolete equipment can then generate additional value. Simply sending everything for recycling may recover raw materials, but it can destroy significantly more value than necessary. Extending the life of equipment before recovering its constituent materials can preserve both commercial and environmental value.
The objective should therefore be to extract the maximum remaining value from every asset, not simply to clear a site.
Urban mining at scale
TXO has seen the scale of this opportunity first-hand. Through major network transformation programmes, we have recovered substantial quantities of copper and other valuable materials, extended the life of technology, returned assets to productive use and unlocked significant commercial and environmental value.

Recovery needs to be designed in
These figures illustrate an important point. Legacy infrastructure is not necessarily a liability waiting to be disposed of. Managed strategically, it can become a source of value that helps fund the transition to what comes next.
The greatest opportunity comes when recovery is considered as part of the wider network transformation strategy, rather than as an activity that begins once infrastructure has already been decommissioned.
That requires an end-to-end view. Organisations need to understand what technology and infrastructure they have, where it is located, what needs to change and what can be reused, resold or recovered as networks evolve.
TXO works across the entire technology lifecycle, from auditing existing estates and designing, building and maintaining networks to decommissioning infrastructure and recovering its remaining value. Our capabilities span network design, installation and commissioning, field engineering, managed services, test and repair, de-installation, reuse, resale and recycling.
This approach means recovery can be designed into transformation from the outset. Equipment that still has operational value can be redeployed, tested or repaired. Assets with a viable secondary market can be resold. Components can be harvested for reuse, while copper and other valuable materials can be recovered from infrastructure that has genuinely reached the end of its useful life.
By considering these routes together, organisations can maximise the value of their existing infrastructure while helping to fund and support the transition to what comes next.
Copper supply security is also a circularity question
There is an understandable focus on where the critical minerals needed for the next generation of infrastructure will come from. But supply security is not simply a question of what countries can extract. It is also about how effectively economies retain and recirculate the materials they already possess.
Every tonne of copper recovered from redundant infrastructure is material that can return to the economy rather than remain stranded in an obsolete network.
Every piece of equipment successfully refurbished and reused can also delay demand for newly manufactured technology and the raw materials required to produce it.
That makes circularity more than an environmental consideration. It is increasingly a question of resource efficiency, resilience and economics.
The organisations that approach decommissioning strategically can reduce waste, return valuable materials to the economy, generate commercial returns and help finance the next generation of infrastructure.
The next copper mining boom does not have to be defined solely by new shafts in the ground. Part of it could start much closer to home, with the technology, infrastructure and old cables already beneath our feet.
