Resource Conservation and Secondary Use of Oil Waste as Elements of the Circular Economy in the Oil Refining Industry of the Republic of Kazakhstan

Abstract

The purpose of this study is to substantiate the importance of resource conservation and secondary use of oil-containing waste in the oil industry of the Republic of Kazakhstan in the context of implementing circular economy principles. The methodological framework of the research is based on system, structural-dynamic, and comparative analysis methods, as well as economic and mathematical methods for calculating specific and relative indicators of resource efficiency, and the case study method for analyzing practical experience in processing oil-containing waste. The empirical basis of the study includes official statistical and ведомственные data from authorized government bodies, as well as corporate reports of oil and gas companies.

The research findings confirm that the integration of circular economy principles into the oil waste management system contributes to reducing landfill disposal volumes, increasing resource efficiency, and enhancing the environmental sustainability of the oil industry. The study concludes that a transition from a linear oil waste management model to a circular system focused on incorporating oil-containing waste into secondary economic circulation and strengthening the sustainable development of the oil and gas complex of the Republic of Kazakhstan is both feasible and justified.
