The modern manufacturing sector plays a crucial role in reducing the negative environmental impacts of human activities, particularly given its significant contribution to global CO2 emissions. Scientific research is essential to understand how manufacturing processes affect the environment and to develop strategies that minimize these impacts. This review paper focuses on how metal shaping processes can reduce environmental impacts across different stages of a metal component’s life cycle, beyond just the manufacturing phase, including material production and end-of-life stages. By raising awareness of the environmental effects of these processes, new strategies for energy and resource efficiency can be identified, supporting circular economy practices. The paper analyzes various aspects of metal shaping, such as machine tool architectures, process parameters, and manufacturing approaches, to quantify improvements in environmental indicators. It also explores innovative material efficiency strategies like remanufacturing, reshaping, and relocating, which enhance recycling and reuse. The goal is to provide a comprehensive overview of the environmental impact of metal shaping processes, highlighting their role in sustainable manufacturing and identifying areas for further research. Ultimately, this study aims to advance resource- and energy-efficient practices, contributing to reduced CO2 emissions and promoting long-term sustainability in manufacturing.
