Quality

Our facilities implement documented quality management systems and robust process controls designed to support compliance with applicable customer specifications and regulatory requirements. These systems focus on process consistency, continuous improvement, and corrective action to help ensure products are manufactured in accordance with defined requirements.

Quality objectives and performance are monitored through established internal processes and audits appropriate to each facility.

Environmental

Environmental stewardship and responsible resource use are integral considerations within our operations. Guided by Westlake’s corporate sustainability goals, our ISO 14001:2015‑aligned Environmental Management Systems integrate environmental considerations into operational planning and decision‑making to support compliance with applicable regulations.

Where feasible, we aim to consider raw materials with improved sustainability, implement product designs that support circular economy initiatives and work toward reducing the overall environmental footprint of our operations

These efforts vary by facility and are implemented in accordance with local regulatory frameworks and business requirements.
