The transition toward sustainability in the energy sector necessitates innovative approaches to material management, particularly in large-scale infrastructure projects. This paper explores strategies for enhancing cost efficiency through the reuse of materials, emphasizing their economic and environmental benefits. It provides a theoretical framework grounded in sustainable material management principles and examines the challenges associated with inconsistent material quality, logistical complexities, and regulatory constraints. Opportunities for progress are highlighted, including emerging technologies like additive manufacturing, scalable strategies such as steel recycling, and cross-industry collaborations that expand the scope of material reuse. Practical recommendations for stakeholders focus on integrating reuse into project design, investing in advanced technologies, fostering partnerships, and advocating for supportive policies. The paper also identifies future research directions, including the development of recyclable materials, scalable recovery technologies, and standardized reuse guidelines. The energy sector can harness material reuse to achieve cost efficiency and sustainability by addressing these issues, contributing to the global push for a circular economy.
