U.S. plastics industry that boomed over past decade is beginning to cool, new research shows
To help track the buildout of the plastics industry, EIP and Material Research (MR3) have developed an inventory of production capacities for plastics plants across the U.S. According to EIP's most recent update, 2025 saw a wave of setbacks for the industry. That includes the permanent closure of Westlake’s PVC plant in Aberdeen, Mississippi, as well as the company’s idling of several production units that support the production of PVC plastics in Lake Charles, Louisiana, because of “persistent, challenging market conditions.” Alpek also shut down its PET plastics facility in Fayetteville, North Carolina, as part of a “cost reduction” initiative.
