The development of large fields in remote regions, such as the Kovykta gas condensate field, involves serious logistical and environmental challenges. The lack of infrastructure and distance from populated areas make traditional waste disposal methods inefficient and expensive. The presentation details a case study of Gazstroyprom, a company that faced the problem of accumulating carbon-containing waste (used tires, oils, oil-containing materials) at construction sites. During one year of field development, about 4,000 cubic meters of such waste were generated, and the costs of their removal and disposal by third-party contractors exceeded 64 million rubles.
To solve the problem, the company turned to modern processing methods. The speaker analyzes the reasons for choosing low-temperature pyrolysis technology. This method allows processing hard-to-decompose waste (with a natural decomposition period of up to 300 years) with minimal environmental impact. The process occurs in the complete absence of oxygen, which eliminates direct combustion and minimizes harmful emissions. An important factor was the ability to use modular units capable of operating in the harsh climatic conditions of Siberia and the Far North.
The implementation of an in-house pyrolysis unit required an investment of about 72 million rubles (including equipment purchase, site preparation, and first-year operating costs). However, as the speaker shows using calculations, the project's payback period is only 3-3.5 years. At the same time, the company not only saves on third-party contractor services but also obtains secondary resources: pyrolysis fuel, gas, and ash-mineral residue, which is used to reinforce roads at the field. The environmental effect is expressed in the disposal of 90% of carbon-containing waste from the construction cycle and a significant reduction in the environmental burden.
