Application of circular economy principles to midstream infrastructural sector: A review of strategies for waste minimization and recycling

Circular economy in midstream operations promotes resource reuse, waste reduction, and sustainable pipeline life cycle management. The transition toward a sustainable oil and gas industry needs to be enabled through the adoption of this concept, especially in the midstream sector, where environmental impact is high. This review focuses on practices in the waste minimization and recycling strategy of midstream infrastructure, including material recycling, reuse of processing debris and the conversion of waste into valuables. It underlines potential lifecycle environmental savings and resource efficiency, besides emphasizing on how innovative approaches are important in mitigating the ecological footprint of midstream activities. It also points out the knowledge gaps on practical integration of the circular economy principles within this very industry and came up with actionable recommendations for industry stakeholders. Through the analysis of the most recent published literatures and case studies of successful implementation, it has been indicated that many companies that use these techniques have succeeded in reducing waste output by over 30%. Conclusively, full scrutiny by this review has helped to attain a holistic approach towards sustainability in the oil and gas industry through wider adoption of recycling and sustainable practices in midstream operations.
