Waste stewardship

We recognise that during our business activities large volumes of waste are generated (including from metal production and general (non-mining) waste) and mining waste, such as overburden, tailings, and barren rock. We strive to implement the best available management practices in this area, in order to use natural resources rationally and, as a result, reduce waste generation. Our waste management strategy comprises the following areas (listed in order of priority):

A total of 8.7 million tonnes of non-mining waste and by-products were generated by EVRAZ enterprises in 2020.

Non-mining waste 7.9 8.4 8.7
Mining waste 232.0 198.8 135.6

In line with the Environmental strategy, EVRAZ seeks to increase amounts of recycled and reused waste. In 2020, 48.9 million tonnes of waste (including mining waste) were reused. The Group uses non-hazardous mining waste for land rehabilitation purposes and to build dams and roads, where possible. In 2020, 38.6 million tonnes of this waste were reused, which made up 79% of total waste reused.

Case study Recycling used tyres

We seize any opportunity that allows us to use our waste more rationally. One example here would be used tyres from large-sized dump trucks being recycled at Raspadskaya Coal Company. Tyres are non-hazardous waste with a low level of environmental impacts, however, when they decompose they can release harmful substances.

Tyres are non-hazardous waste with a low level of environmental impacts, however, when they decompose they can release harmful substances.

As they accumulate, used tyres are transported from the mine by a contractor. Then they are cleaned of metal parts and fittings and crushed into fragments. The rubber is used to make soft coverings for pathways and roofing material, and it can be added to paving slabs. Also, around 30% of tyres are used to build safety barriers on roads.

Over 200 used tyres are recycled at Raspadskaya per year, which is more than 500 tonnes of waste.

Recycling used tyres

Waste from metal production is stored at tailings storage facilities (TSF). EVRAZ owns three operating TSF, located at EVRAZ ZSMK and EVRAZ KGOK. The Group considers the safety of TSF to be a top priority, as their operation entails significant environmental risks. We have elaborated a dam safety management system that ensures compliance with applicable legislation and covers all stages of the process. The TSF service life comprises design, construction, operation, and closure. We also carry out continual safety monitoring procedures and our TSF are regularly audited by both internal and external specialists, as well as inspectors from regulatory bodies.
