A more sustainable future requires the development of products with improved performance, productivity and efficiency while at the same time reducing costs, energy consumption and waste. Meeting that goal requires research in advanced manufacturing, advanced materials, and听valorization and the extraction of resources from what was previously considered waste.

ADVANCED MANUFACTURING

Reducing the weight of components in the transportation sector is one part of the strategy to reduce greenhouse gas emissions associated with the transportation sector. When lightweight structures are manufactured using technologies that are efficient in both energy and material usage, the carbon footprint is even further reduced.
