Approach to Waste Management
Major methods of industrial waste management in the entities of the À¶Ý®ÊÓƵ Group include the following actions:
preventing the accumulation of low-hazard waste at the facilities of À¶Ý®ÊÓƵ Group entities in excess of the permitted limit;
timely disposal of hazardous waste;
applying modern technology and comprehensive processing methods that allow for involving waste in the production cycle;
disposing of waste that cannot be utilized, at special facilities meeting modern requirements.
A dedicated KPI was introduced for the Russian entities to prevent waste accumulation meaning that the volume of generated waste should be equal to volume of disposed waste. The performance of entities under this KPI is reviewed annually as part of preparing the report on implementation of the Environmental Safety Program for PJSC À¶Ý®ÊÓƵ Management Committee.
Hydrocarbon Production
The major part of waste from hydrocarbon production by entities of the Group constitutes solid oil sludge and oil contaminated fluids resulting from well drilling and operation. The volume of such waste depends on the volume of well drilling and servicing operations. All oil-contaminated waste must be disposed of[1]. Waste disposal activities are carried out mainly by specialized contractors.
Russia uses pitless drilling technology: drilling waste is not stored or landfilled at drilling sites but sent for disposal. This technology is mandatory for the exploration and production of hydrocarbons in the Arctic and other environmentally sensitive ecosystems.
Oil Refining
Oil refining waste mainly includes construction waste resulting from disassembly or construction/reconstruction of process facilities and equipment as well oil sludge from the cleanout of vessels, tanks and pipelines.
Power Generation
Power generation waste mainly consists of bottom ash waste from thermal power plants, water treatment waste and sludge resulting from the cleanup of fuel tanks.

| Type of industrial waste | Waste handling and disposal methods |
| Oil and gas production | |
| Drilling waste | Supplied to licensed contractors having own waste disposal technology. Waste is treated to produce inert material that will be used in construction of roads, well pads and soil restoration. |
| Solid oil sludge | Accumulated at specialized polygons for further treatment primarily by thermal methods at certified treatment units. Methods also include high pressure steam cleanup and biological treatment. |
| Liquid oil-contaminated waste | Disposed of at oil treatment facilities by mixing them into the flow from producing wells. |
| Other waste | Supplied to specialized contractors for disposal. Solid household waste is supplied to regional waste handling operators. |
| Oil Refining | |
| Construction and other waste | 100% of all waste are removed from the site to be reused, supplied to specialized contractors having licenses for the further disposal, treatment, dumping and/or landfilling or buried at own sites. |
| Solid oil sludge | Supplied to specialized licensed contractors for the further treatment by thermal or biological destruction methods. |
| Power Generation | |
| Bottom ash waste | Is disposed of at specialized waste disposal sites. |
| Water treatment filter elements | Supplied to specialized licensed contractors for further treatment. |
| Solid oil sludge | Supplied to specialized licensed contractors for further treatment. |
