Materials waste reduction

Research output: Chapter in Book/Report/Conference proceedingChapter


Materials waste reduction presents the most significant holistic benefits within the waste hierarchy, providing both economic and environmental merits. This chapter reviews current composite consumption and corresponding waste volumes, with the aim to provide composite engineers with the most relevant information to improve material yield. Material waste generated during part production is shown to range from 0% to 60%, depending on material, design, and process. This chapter provides industrial data and case studies for illustration and benchmarking, categorising the waste produced during lay-up, finishing, curing and storage. The impact of manufacturing processes on waste generation is discussed and different processes are compared. Finally, strategies for improving material yield are presented and reviewed. It is shown that process wastes can be reduced, but only efficiently by adopting a holistic design for manufacture approach.
