Sustainability Issues in Materials and Manufacturing Engineering

The increasing threats posed by climate change, resource depletion, and environmental degradation have prompted a global reassessment of materials and manufacturing practices. This paper critically evaluates sustainability challenges in materials and manufacturing engineering, emphasizing interdisciplinary efforts to minimize environmental impacts while maintaining performance and economic viability. Key topics include sustainable material selection, energy and resource efficiency, environmentally conscious manufacturing, and the role of digital technologies. Also discussed as critical enablers of sustainability are the integration of circular economy principles, development of bio-based and recyclable materials, and deployment of smart manufacturing systems. Drawing on recent studies and international best practices, the paper outlines major obstacles and future research directions necessary to advance sustainable practices across the lifecycle of engineering products. Offering a novel, interdisciplinary synthesis of emerging strategies for advancing sustainability in materials and manufacturing engineering, this paper provides valuable guidance for researchers, engineers, and policy-makers seeking to reduce environmental impacts while maintaining industrial competitiveness.
