KMG’s operations inevitably involve generation of considerable volumes of hazardous waste. In order to minimise the impact of waste on the environment, KMG continually plans and implements waste management activities. Such activities comprise accounting for generated and accumulated waste (including that of contractors), gradual reduction in waste generation volumes, safe storage of waste until it is reused or treated, KMG allocates significant funds to treat the waste generated and accumulated across all its contract territories.
The waste management performance is regularly reviewed and assessed within the KMG Group, advanced methods and modern technologies of waste management are considered so as to be implemented at production facilities.

Elimination of historical contaminations and cleaning up the oil-contaminated territories.
The critical task that KMG faces today is the liquidation of historical contamination and clean-up of oil-contaminated areas. In this regard, studies were conducted to take inventory of historical contamination; plans to liquidate all historical contamination were developed subject to the specifics of each field, region, and climatic conditions. In addition, on 6 August 2019, a Memorandum of Environmental Cooperation was signed between the Kazakhstan Ministry of Ecology, Geology and Natural Resources and KMG, which is aimed at disposal/treatment of waste stored in the unorganised sludge collectors (OMG) and clean-up of oil-contaminated lands in Mangistau Region.
In order to increase control and effectively organise oily waste liquidation and oil-contaminated land clean-up operations, the entities of the KMG Group have established a working group that included KMG’s top management as well.
On 2 October 2019, the KMG Historical Waste Disposal and Treatment Technologies Forum was held in Aktau. The Forum was attended by over 30 companies that provide such services. The objective of this event was to meet with Kazakhstan’s providers of oily waste treatment/disposal services and to explain them the requirements for the quality, scope and timing of services for the KMG historical waste treatment/disposal so as to help them assess their capabilities and decide on the use of new technologies.
The Forum also presented a category-based procurement strategy – Waste Disposal (historical contamination), which will further serve as a basis for the procedure for procuring historical contamination disposal and oil-contaminated area clean-up services.
* In 2019, inventory of “historical” oil-contaminated areas of JSC MangistauMunaiGas fields was taken.
* - Areas of contaminated lands are annually updated as part of conducted inventories and projects for the reclamation of disturbed lands.
Generation of Drilling Waste
In 2019, KMG’s upstream companies generated 193.19 thousand tonnes of drilling waste (11% more than in 2018), including: 59.24 thousand tonnes – waste drilling mud; 133.948 thousand tonnes – drilling sludge. All drilling waste generated by the KMG Group’s upstream companies are handed over for disposal by specialised organisations. The methods of further waste disposal used by these companies include inertisation, thermal method, chemical method, biological remediation and burial on specialised landfills.
