At AST Recycling, we believe that every material has value — especially when it comes to critical metals like tungsten.

Tungsten is one of the hardest and most heat-resistant metals on earth. Its strength, durability, and high melting point make it essential in industries such as mining, manufacturing, aerospace, electronics, and automotive production. But what happens when tungsten tools, inserts, or components reach the end of their life?

Instead of sending them to landfill, they can — and should — be recycled. 

Why Tungsten Is So Important

Tungsten (chemical symbol W) is classified as a critical raw material globally due to its limited supply and strategic importance. It is widely used in:

• Tungsten carbide cutting tools

• Drill bits and mining tools

• Aerospace components

• Electrical contacts

• Lighting filaments

• Heavy-duty wear parts

Mining new tungsten is energy-intensive and geographically concentrated. Recycling reduces dependence on primary mining while conserving natural resources.

How Tungsten Is Recycled

Tungsten recycling typically involves:

Collection and Sorting

Scrap tungsten carbide tools, drill bits, inserts, and industrial components are collected and sorted according to grade and composition.

Processing

The material is crushed and processed to remove impurities. Advanced recycling techniques such as chemical treatment or zinc recycling are often used to reclaim high-purity tungsten powder.

Refining & Reuse

Recovered tungsten powder can be reprocessed and reused in the production of new tools and industrial applications — without losing its performance properties.

Tungsten can be recycled multiple times without degrading its core characteristics, making it ideal for a circular economy model.

The Environmental Benefits

Recycling tungsten:

Reduces landfill waste
Conserves natural tungsten reserves
Requires significantly less energy than primary mining
Lowers carbon emissions
Supports responsible supply chains

For companies in manufacturing and mining — especially here in South Africa — recycling tungsten isn’t just environmentally responsible, it’s economically smart.

Why Partner with AST Recycling?

As a responsible and ISO-certified recycler, AST Recycling focuses on compliant, transparent, and efficient recovery of valuable metals. We understand the importance of traceability, compliance, and maximising value for our suppliers.

If your business generates tungsten scrap — from carbide inserts, drill bits, or production off-cuts — we can help you:

• Assess material grades

• Maximise return on value

• Ensure responsible processing

• Contribute to a more sustainable supply chain

Recycling Waste into Sustainable Resources

Tungsten may be one of the toughest metals on earth — but it deserves a second life.
