The Copper Hidden in Old Cables: Why Urban Mining Is Creating a New Opportunity for Cable Recyclers

September 2026 | Recycling Industry News

When an old electrical cable is removed from a building, factory, telecommunications network or infrastructure project, it may look like nothing more than scrap.

But inside that discarded cable is a material that is becoming increasingly valuable: copper.

As electrification, renewable energy, data centers and digital infrastructure continue to expand, global demand for copper is increasing. At the same time, the copper market is facing supply constraints and significant price volatility. In September 2026, copper prices reached record levels on major markets, with supply concerns and strong long-term demand contributing to the rally.

This is changing the way the recycling industry looks at old cables.

Instead of treating them simply as waste, more businesses are beginning to view discarded cables as a form of urban mining.

Old Cables Are Becoming the New Urban Mine

Traditional mining extracts copper from ore beneath the ground.

Urban mining takes a different approach: it recovers valuable materials from products and infrastructure that have already been manufactured and used.

Old power cables, communication cables, industrial wires and electrical equipment can contain significant amounts of copper.

The International Energy Agency has highlighted copper recycling as particularly important for future mineral supply. Its analysis indicates that available copper scrap could increase substantially over the coming decades, while improving collection, sorting and secondary processing will be essential to capture this potential.

The European Commission's Joint Research Centre has also identified cables and other electrical equipment as waste streams with significant potential for recovering valuable raw materials.

In other words, the next source of copper may not always be a new mine.

Some of it may already be sitting inside yesterday's infrastructure.

A Real-World Example: BT Is Turning Old Cables into a Valuable Resource

The trend is already visible in the telecommunications industry.

In the UK, BT is replacing legacy copper telecommunications infrastructure as it expands its full-fibre network. The company has already recovered more than 22,000 tonnes of copper since 2023 and expects to reclaim up to 200,000 tonnes from its old network over time.

The financial implications are significant. With copper prices near record levels, BT expects the value generated from selling recovered copper to become an important source of financial return.

This example demonstrates an important change in the economics of infrastructure:

Decommissioning an old cable network does not necessarily mean disposing of a waste stream. It can also mean recovering a valuable raw material.

For smaller cable recyclers, scrap dealers and waste-processing companies, the same principle applies on a different scale.

A truckload of discarded cables may contain a substantial amount of recoverable copper.

The challenge is how to separate it efficiently.

Why Copper Wire Granulation Matters

Scrap cable is not simply copper.

A typical cable may contain copper conductors surrounded by plastic insulation and other materials.

If the cable is sold as mixed scrap, the recycler may not fully capture the value of the copper contained inside it.

A copper wire granulator provides a mechanical processing route designed to reduce scrap cable into smaller particles and separate the copper from non-metallic materials.

The basic concept is straightforward:

Scrap cable → Granulation → Separation → Copper granules + non-metallic material

The recovered copper can then enter subsequent recycling and metal-processing channels.

The exact recovery result depends on the cable type, copper content, feedstock condition, particle size and equipment configuration. Therefore, professional recyclers should evaluate their actual feedstock before selecting a machine.

The Business Case Is Changing

For many years, the decision to invest in cable recycling equipment was mainly associated with waste-management requirements.

Today, the calculation is increasingly about material recovery and resource value.

Consider the difference between these two approaches.

Traditional waste approach

A recycler receives mixed scrap cable.

The cable is difficult to handle.

The recycler sells it as low-value mixed scrap or sends it to another processor.

Resource-recovery approach

A recycler receives scrap cable.

The cable is processed through a suitable granulation and separation system.

Copper and non-metallic materials are separated.

The recovered copper becomes a more valuable secondary material stream.

The second approach requires investment in equipment and processing infrastructure, but it also creates an opportunity to capture more value from the same incoming material.

That is why copper wire granulators are becoming increasingly relevant to modern scrap-processing businesses.

What Kind of Businesses Can Benefit?

Copper wire recycling is not limited to large industrial plants.

Depending on feedstock availability and processing requirements, potential users of copper wire granulation equipment can include:

• Scrap metal recycling companies

• Electrical cable recycling businesses

• Waste electrical and electronic equipment processors

• Demolition and construction waste recyclers

• Telecommunications infrastructure recyclers

• Electrical contractors handling cable waste

• Metal trading and scrap-processing companies

• Industrial waste management businesses

The most important factor is not simply company size.

It is access to a consistent supply of suitable scrap cable.

If a business regularly handles discarded copper-containing wires and cables, processing the material internally may create an opportunity to capture additional value.

JIACUI: Copper Wire Granulators for Different Recycling Scales

Henan Jiacui Intelligent Equipment Co., Ltd. (JIACUI) manufactures copper wire granulators for different cable recycling requirements.

Its product range covers multiple machine sizes and processing capacities, allowing buyers to evaluate equipment according to their expected material volume and operating conditions.

The RC-CWG46A, for example, is specified with an output of approximately 60–80 kg/h, with a total power rating of 5.58 kW.

For a higher processing requirement, the RC-CWG260 is specified at approximately 150–170 kg/h, with a total power rating of 9.05 kW.

JIACUI also offers larger models.

The RC-CWG400 is specified at approximately 350–400 kg/h, while the RC-CWG660 is specified at approximately 600–650 kg/h.

For larger-scale operations, the RC-CWG800 is specified at approximately 700–900 kg/h, and the RC-CWG1000 at approximately 900–1,000 kg/h.
This range means that a recycling company does not necessarily need to start with a large industrial system.

The right starting point is the actual quantity and type of cable available for processing.

From Scrap Cable to Copper Granules

One of the key advantages of granulation is that it changes the physical form of recovered copper.

Instead of handling long, tangled lengths of cable, the recycling process can produce a granular copper material that is easier to collect, store and transport.

At the same time, the plastic insulation becomes a separate material stream.

This separation is important because it allows recyclers to manage the recovered materials according to their respective downstream markets.

Recent scientific research into electrical-cable recycling has also demonstrated the importance of particle size reduction and subsequent separation technologies in producing high-quality copper granules from cable scrap.

For equipment buyers, this highlights an important point:

A cable recycling machine should be evaluated as part of a material-recovery process, not simply as a shredding machine.

Why AI and Electrification Could Increase the Value of Cable Recycling

The copper story is no longer limited to traditional electrical infrastructure.

AI data centers, renewable energy systems, electric vehicles, grid modernization and industrial electrification all require large amounts of electrical infrastructure.

Copper is particularly important because of its electrical conductivity and widespread use in power systems.

The resulting demand is putting increasing pressure on the global copper supply chain.

The current market illustrates this clearly. Copper prices have risen sharply in 2026, with market participants watching mine supply, inventories and potential trade restrictions closely.

This creates an interesting paradox.

The world needs more copper for future infrastructure.

At the same time, millions of tonnes of copper-containing products are already sitting inside existing infrastructure and reaching the end of their useful lives.

That creates an opportunity for recycling.

The Future of Copper May Be Above Ground

Mining will continue to play a major role in global copper supply.

Recycling will not eliminate the need for new copper mines.

But the growing importance of secondary copper means that the industry can no longer afford to overlook material that has already been extracted and manufactured.

The International Energy Agency estimates that copper scrap availability could rise from around 16 million tonnes today to approximately 19 million tonnes by 2030 and 27 million tonnes by 2050 under its stated scenario. It also emphasizes better collection, sorting and secondary processing as key ways to unlock this resource.

This is where the concept of urban mining becomes especially relevant.

A retired telecommunications cable.

A demolished building.

An old industrial machine.

A discarded electrical installation.

A bundle of scrap wires.

Each may contain copper that has already passed through the most resource-intensive stage of its life: extraction from the ground and initial production.

Recovering that copper gives the material another opportunity to enter the industrial cycle.

What Should Buyers Consider Before Purchasing a Copper Wire Granulator?

For businesses considering their first copper wire recycling machine, the most important question is not:

“Which machine has the highest capacity?”

A better question is:

“Which machine matches our actual cable feedstock and business model?”

Before purchasing equipment, buyers should consider:

Cable Type

What types of wires and cables will be processed?

Are they single-core, multi-core, flexible wires, communication cables or mixed scrap?

Feedstock Volume

How many kilograms of cable are available per day or month?

A machine should be matched to realistic material availability rather than an assumed maximum capacity.

Required Throughput

Different recycling businesses have different production targets.

JIACUI's product range provides options from approximately 60–80 kg/h to approximately 900–1,000 kg/h.

Installation Conditions

Available floor space, electrical supply, feeding arrangements and material-handling systems should all be considered.

For example, JIACUI's larger models require substantially more installation space than its compact models, so the machine footprint should be evaluated before purchasing.

Downstream Material Market

The value of a recycling operation ultimately depends on what happens after separation.

Buyers should understand who will purchase the recovered copper and non-metallic materials, what quality requirements apply and what additional processing may be necessary.

Copper Recycling Is Becoming a Strategic Business, Not Just Waste Treatment

The transformation of old cables into copper granules illustrates a larger shift taking place across the recycling industry.

Waste is increasingly being evaluated according to the resources it contains.

Copper is an especially important example.

The metal inside a discarded cable has already been mined, refined and manufactured into a useful product.

When that cable reaches the end of its first life, the copper does not necessarily lose its value.

It can become a secondary raw material.

As copper demand grows, infrastructure is upgraded and global supply chains become more sensitive to disruptions, recovering this material becomes increasingly attractive.

For recyclers, the opportunity is therefore not simply to process more waste.

It is to recover more value from the waste they already receive.

The Urban Mine Is Already Here

The next copper mine may not always be thousands of meters underground.

Sometimes it is an old cable buried beneath a road.

Sometimes it is a telecommunications network being replaced by fiber.

Sometimes it is a pile of electrical wires waiting in a scrap yard.

The infrastructure of the past is gradually becoming a resource for the infrastructure of the future.

For businesses operating in scrap cable recycling, a copper wire granulator can be an important link between these two worlds—turning discarded cables into a separated copper material stream that can re-enter the industrial supply chain.

As the global economy becomes increasingly electrified, the ability to recover copper efficiently may become just as important as the ability to produce it.

And for the recycling industry, that makes every discarded cable worth looking at a little differently.
