This study is devoted to optimizing the sustainability of production processes at «KazakhOil Aktobe» LLP, one of the leading companies in the oil and gas industry in Kazakhstan. In the context of global environmental challenges and the need to reduce the carbon footprint, the main goal of the study is to develop recommendations for improving the environmental and economic performance of the company. Analysis of current practices showed potential for significant improvements in energy efficiency, water management and waste management. The study results demonstrate that implementing energy management systems (EMS) and using renewable energy can reduce operating costs by 20–25% and carbon emissions by 30–35%. The introduction of modern wastewater treatment and recycling methods can reduce freshwater consumption by 30–40%, and the use of biotechnological waste management methods, such as anaerobic digestion, converts waste into useful resources and reduces its volume by 40–50%. The proposed recommendations provide concrete steps to achieve sustainable development and can be useful not only for «KazakhOil Aktobe» LLP, but also for other companies in the industry. The study confirms the need to implement advanced practices and technologies to promote environmental responsibility and economic prosperity in Kazakhstan’s oil and gas industry.
