PRINCIPLES OF CIRCULAR ECONOMY IN CREATING CLOSED CYCLES FOR PROCESSING SEWAGE SLUDGE INTO ORGANIC FERTILIZER

Abstract

The article is devoted to the prospects for implementing the principles of a circular economy in the oil and gas sector. The purpose of this study is to consider the possibility of creating closed cycles for processing sewage sludge into organic fertilizer. In view of the fact that the resulting wastewater sludge at an oil and gas enterprise can be processed into an effective organic fertilizer, we decided to calculate the effectiveness of this process and identify its feasibility. The methodological justification is built through the use of comparative and calculation-analytical analysis methods, which include the collection and analysis of the main indicators of the development of the organic fertilizer market in the region. The article analyzes literary sources on research issues in recent years. A SWOT analysis of the factors influencing the creation of closed cycles for processing sewage sludge into organic fertilizer was carried out. As a result of the analysis, potential opportunities and threats for the development of a circular economy were identified. Strengths and opportunities were found to outweigh weaknesses and threats. Among the strengths and opportunities, the following prevail: the possibility of recycling sewage sludge, reducing environmental pollution, reducing the carbon tax at enterprises in the oil and gas sector, building a circular economy at the enterprise. The efficiency of processing sewage sludge into organic fertilizer was calculated, which corresponds to the principles of a circular economy. The calculation showed the feasibility of using a circular economy in the oil and gas sector.
