WSI announced today that its warehouse operations at a dedicated manufacturing customer facility in the greater Houston area have earned Operation Clean Sweep® (OCS) Logistics Certification.
The certification is part of a program launched by the Plastics Industry Association and the American Chemistry Council in January 2025. It verifies that more than 25 required management practices for preventing plastic resin loss have been successfully implemented at the warehouse. WSI passed this audit with no deficiencies.
The achievement is particularly significant for a 3PL, since one of the goals of the OCS program is to extend accountability beyond manufacturing facilities. “Accountability and safety are two of our core values at WSI” said Bob Schroeder, CEO of WSI. “We are proud to partner with customers who are equally committed to being responsible stewards of their products.”
The certification builds on WSI’s established leadership in chemical logistics. In early 2025, WSI was also named Responsible Care® Partner of the Year by the American Chemistry Council.
“Our customers expect audit-ready logistics partners who share their commitment to safety and sustainability,” said Scott Buber, Director of Chemical Operations at WSI. “This certification demonstrates our commitment and capability to meet rigorous environmental standards, whether we own the facility or operate it for a manufacturing partner.”
