Plaquemine Complex 2018 Chlor-Alkali, EDC and VCM Expansion (Phase 1)

2018 Plaquemine expansion — new chlor-alkali unit, new ethylene dichloride unit and new vinyl chloride monomer unit at Shintech's Plaquemine PVC and caustic-soda complex. First phase of Shintech's multi-phase Plaquemine build-out; completed mid-2021. Distinct capital commitment from the 2021 and 2026 Plaquemine announcements (each additional capital, not cumulative), which are excluded from this record's investment and job figures.

Why this project qualifies

With $1.5 billion in facility-specific investment and 120 permanent operating jobs announced, this project clears both of AFT's qualifying thresholds ($100 million in facility-specific investment OR 100 permanent operating jobs). It is also confirmed by official public sources and involves a physical manufacturing facility in the United States.

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 composites. Projects in this category represent multi-billion-dollar capital programs and long-lived industrial infrastructure that supply nearly every other sector of manufacturing. The category includes plastic resins and plastic/rubber products not assigned to a more specific category. Tires and vehicle-specific parts belong in Automotive. Finished packaging belongs in Packaging & Paper.
