Recycling has become increasingly important in the mining industry in recent years. By recycling and reusing materials such as steel, metals and other valuable resources, the need to extract virgin material is reduced, which in turn reduces environmental impact and encourages the development of more sustainable practices. Additionally, Epiroc notes some geopolitical issues in the world that could become a potential bottleneck for a sustainable manufacturing process. In 2023, recycling has become a priority in Epiroc’s work towards sustainability.
Epiroc implements recycling program to manufacture sustainable tungsten powder
By using recycled tungsten carbide, Epiroc obtains tungsten powder identical to virgin powder. «We must do everything possible to contribute to a more sustainable world, with less waste and emissions. Our new recycling program is one activity that brings us closer to that goal,” says Pavel Vedeneev, regional business development director at Epiroc Rock Drilling Tools.
Steps towards sustainability
In April 2023, Vedeneev and his team took the first step towards the recycling program. By the end of the year, the goal is to have implemented the process in seven selected markets on different continents. «Next year we are going to expand it by developing new areas. We are eager to continue moving forward,” says Pavel Vedeneev.
The recycling process
The recycling process is divided into two levels. The first requires separating the steel from the tungsten carbide inserts, and the second is a more complicated process that requires a high-tech chemical method. The inserts are first reduced to the atomic level, in order to obtain a powder equal to the virgin powder of the mine. «Our goal is to reach the first level in the regions where our customers use our bits and are close to their operations. This means that only carbide inserts that are ultimately turned into powder are sent to our second-tier production system in Europe. Level two requires specialized knowledge. This also means that we do not need to ship large containers around the world. Therefore, finding regional business partners who can help us with the separation is high on my agenda at the moment,” highlights Pavel Vedeneev, Regional Business Development Manager for Epiroc Rock Drilling Tools.
Tungsten carbide in industry
In industry, efficiency is essential. Maximizing production at the lowest cost, while maintaining ethical practices, is key. Metal tools, used constantly, can wear out quickly, which is why many industries have turned to tungsten carbide. This inorganic chemical compound, made up of tungsten and carbon atoms, occurs as a fine gray powder that can be molded and pressed for use in jewelry, industrial machinery, tools and abrasives.
Advantages of the recycling program
- Environment: The use of recycled steel and tungsten carbide reduces carbon emissions.
- Sustainability: By diversifying carbide supply, including recycled material, Epiroc can ensure customers’ sustainability efforts.
- Economy: Recycling materials, such as tungsten carbide, increases production efficiency and saves costs.
