6.2 Remanufacturing

Remanufacturing breathes new life into used products, restoring them to like-new condition. This process extends product lifecycles, reduces waste, and conserves resources, making it a key player in green manufacturing and the circular economy.

The remanufacturing process involves disassembly, cleaning, inspection, and component replacement. It offers significant environmental and economic benefits, creating jobs and reducing costs while minimizing the environmental impact of manufacturing and disposal.

Definition of remanufacturing

• Remanufacturing restores used products to like-new condition through a standardized industrial process
• Plays a crucial role in green manufacturing by extending product lifecycles and reducing waste
• Involves disassembly, cleaning, inspection, and replacement of components to meet original equipment manufacturer (OEM) specifications
