Renewable and Sustainable Energy Reviews, cilt.234, 2026 (SCI-Expanded, Scopus)
The aerospace industry faces urgent pressure to reduce emissions and resource use while increasing performance. Manufacturing methods, such as additive manufacturing (AM), subtractive manufacturing (SM), and hybrids, significantly impact energy use and carbon footprint. This review examines these processes for materials like titanium, aluminum, steel, and polymers within a Life Cycle Sustainability Assessment (LCSA) framework, linking aerospace manufacturing to renewable energy transitions. Studies reveal methodological inconsistencies, which limit comparability. AM enables lightweight designs and reduces waste but is energy-intensive; SM offers precision but generates scrap; hybrid processes improve efficiency and lower emissions. Economic analyses highlight trade-offs among cost, speed, and efficiency. Social factors, such as worker health and supply chain ethics, are less studied, particularly for small firms. The review proposes standard protocols, social assessments, and circular-economy practices, such as recycling, along with digital tools to optimize energy and materials use, aiming to reduce embodied energy, promote circularity, and support decarbonization in the aerospace manufacturing sector.
