Integrated management of the participation of Amura S.l. MC4 (Multi-level Circular Process Chain for Carbon and Glass Fiber Composites) is a European association that aims to establish circular approaches for carbon and glass fibre composites. These materials are indispensable in many technical applications, for which their lightweight and high performance properties are particularly valued. However, European carbon fibre and glass fibre value chains need to be optimised on two main levels: environmental and economic efficiencies.
