Fiber-reinforced polymer products are widely adopted in several industries, although their circularity remains a concern. Mechanical recycling is emerging as a viable solution to obtain mixed fiber-resin granules, suitable for reprocessing into new composite-made parts. However, each reprocessing application demands specific secondary material properties, calling for high adaptability of the recycling system delivering these output fractions. This paper presents a methodology to control mechanical recycling systems to meet desired throughput and particle size specifications, customized to the reprocessing application. The industrial benefits are validated in a real business case focused on circular manufacturing of composite-made electro-mechanical parts.

Abstract
Fiber-reinforced polymer products are widely adopted in several industries, although their circularity remains a concern. Mechanical recycling is emerging as a viable solution to obtain mixed fiber-resin granules, suitable for reprocessing into new composite-made parts. However, each reprocessing application demands specific secondary material properties, calling for high adaptability of the recycling system delivering these output fractions. This paper presents a methodology to control mechanical recycling systems to meet desired throughput and particle size specifications, customized to the reprocessing application. The industrial benefits are validated in a real business case focused on circular manufacturing of composite-made electro-mechanical parts.| File | Dimensione | Formato | |
