Plaquemine Complex 2026 Ethylene, Chlor-Alkali-4 and VCM Expansion (Phase 3)

2026 phased expansion — additional $3.4B capital commitment adding a second ethylene unit, a fourth chlor-alkali unit and a new VCM unit at the Plaquemine complex. Adds 625,000 t/y of ethylene, 500,000 t/y of VCM and 310,000 t/y of caustic soda capacity. Separately announced additional capital on top of the 2018 and 2021 programs per the Louisiana Governor's Office announcement, not a cumulative revision of earlier phases, which are excluded from this record's investment and job figures.

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.
