Why it matters

The chemicals & materials context.

Chemicals and materials manufacturing spans a wide range of essential U.S. production — from petrochemicals, polymers, and industrial gases to fertilizers, specialty chemicals, and advanced materials such as recycled aluminum, rare-earth magnets, and composites. Projects in this category represent multi-billion-dollar capital programs and long-lived industrial infrastructure that supply nearly every other sector of manufacturing.
