Waste management

Эффективное обращение с отходами производства
96 % Share of ash and slag waste in the total of waste generated by the Group
- 42 % Decrease in ash and slag waste generation in 2019 y-o-y.

Inter RAO is developing the draft standards for the waste generation and disposal limits in accordance with the requirements of the state codes. Solid residues from coal burning are the most common type of waste of the Group's energy facilities. Ash and slag waste accounting to a major share of the Group's waste, are classified as hazard class V, i. e. almost causing no negative impact on the environment.

To achieve its environmental goals in rational waste management, the Group carries out activities in the following areas:

  • Increasing the energy efficiency of the operations, energy and resource-saving, enhancement of technological discipline.
  • Arrangement of separate waste collection and, to the extent possible, the beneficial use of any production waste.
  • Exclusion from the production—to the possible extent—of environmentally dangerous and harmful substances and technological processes with a high level of waste, control over ecological features of purchased and used power fuels, materials, and equipment.

Inter RAO Group is working on reducing the removal to landfills for the disposal of industrial waste, including similar solid municipal waste, by selective waste collection and transfer for disposal.

The main type of waste at the Group's power facilities is solid substances generated during coal combustion (ash and slag waste). They make up about 96% of the total volume of all Group waste generated. The ash and slag waste are classified according to the degree of the environmental impacts hazard class V, which means the lowest negative environmental impact. In 2019, the ash and slag waste generation decreased by 42% compared to 2018, amounting to 2,392,000 tons. The main reasons are the reduction in the production of coal generation and increase its efficiency.

In addition, it is worth noting the implementation in 2019 of the following measures aimed at reducing the volume of generated waste and increasing the share of waste transferred for recycling and reuse:

  • In 2019, LLC BGK stopped 100% of the disposal of the following types of waste: petroleum oils, scrap metal, paper and cardboard, cullet, plastic and polythene waste (polypropylene waste packaging and protective helmets, used helmets), soil (sludge from chemical water treatment of water for process needs), and used filter materials (ion-exchange resins, activated carbon).
  • In 2019, a selective collection was implemented with the subsequent disposal of 80% of the assets of PJSC Inter RAO — Electric Power Plants, paper and cardboard, plastic waste.
  • At Moldavskaya GRES, transfer for disposal of electrolyte batteries (150 kg) accumulated at the production facility was organized and assistance was provided to the population in organizing and transferring batteries for recycling.
  • In 2019, at the JV CHPP-2 of JSC Omsk RTS, selective collection of such waste as paper and cardboard, cullet, rubbish from demolition and dismantling of buildings, spent ion-exchange resins and spent office equipment (PC monitors, cartridges) was implemented.
