Waste treatment and disposal

The Company`s treatment of production and consumption waste is carried out at the Eco Centre facilities or Waste Management Complex. The facility ensures cost-efficient and environmentally safe recycling and treatment of drilling cuttings and fluids and is truly considered to be an example of the leading drilling waste management practice in the West-Qazaqstan Oblast.

The best available technologies are applied at the KPO Eco Centre facilities for treating production and consumption waste allowing not only reducing the volume and hazards of waste, but also extracting valuable components as well as treating waste for further reuse. Waste recovery to the process stream exercised by the Company is the best possible way to re-use the waste generated in drilling operations. 

The KPO Eco Centre comprises five waste treatment facilities, as well as a Landfill for their safe disposal: 

  1. Thermo-mechanical cutting cleaning facility (TCC),
  2. Rotary Kiln Incinerator (RKI),
  3. General Purpose Incinerator (GPI),
  4. Liquids Treatment Plant (LTP),
  5. Waste Segregation Unit (WSU).

During 2020, the following activities were completed at the Eco Centre:

Owing to separation of base oil and water from the treated oil-based drilling cuttings, in 2020 the quantity of KPO disposed waste was reduced by 7% from the originally generated volume.
In 2020, 8,571 tonnes of waste were treated, 1,195 tonnes of base oil and water were separated, and 7,227 tonnes of waste treated at the TCC were disposed at the Solid Industrial Waste Landfill.
Through treatment and neutralization of drilling and production waste at the Rotary Kiln Incinerator, the volume of waste (against the originally generated amount) was reduced by an average of 24%. In 2020, 4,600 tonnes of drilling and production waste were treated; 3,504 tonnes of waste treated at the Thermo-Mechanical Cuttings Cleaning Facility were disposed at the Solid industrial waste landfill.
By incineration of wastes at the General Purpose Incinerator, the amount of waste was reduced by 90%. In 2020, 772 tonnes of waste were sent for incineration, following which 73 tonnes of ash were disposed at the Solid industrial waste landfill.
In 2020, 6,603 tonnes of liquid waste were treated. The process resulted in 2,052 tonnes of treated brines and muds, which were sent for re-use – preparation of drilling brines and muds.
In 2020, 1,093 tonnes of solid domestic waste were sent to GPI for incineration, 164 tonnes including waste paper, metal scrap, glass and plastic were segregated and handed over to the specialist organizations for treatment and reuse. 320 tonnes of solid domestic waste were handed over to the specialist organizations for disposal at the Solid Domestic Waste Landfill.
12 cells of the Solid Industrial Waste Landfill were capped and closed at the end of 2020.
