Recycling of tools
We have a recycling program of used cemented carbide tools which will be converted back into basic raw materials for reuse.
Wolfram Bergbau und Hütten, a division within Sandvik and a world-leading tungsten powder and tungsten carbide producer, has a proprietarily developed recycling process which is clean, efficient and provides powder with the same high quality and properties as from virgin raw materials.
Some recycling facts and benefits
- We help our customers manage hazardous waste through buyback programs; we repurchase their used cemented-carbide inserts and rock tools, converting them into tungsten carbide powders, and return them to the customer for reuse in their production.
- We reduce the amount of tungsten extracted from mines. Tungsten is a scarce and finite mineral – estimated reserves of tungsten total about 7 million tons, or 100 years of consumption.
- Recycling activities provide a steady supply of tungsten as well as a safe supply, since tungsten is classified as a conflict mineral by the US SEC Dodd Frank Act, implying that the source of the tungsten needs to be traced. The recycling schemes use up to 70% less energy and emit up to 40% less carbon dioxide than production with virgin raw materials.
