Operation Clean Sweep

Borealis is committed to prevent plastic from leaking into the environment, for example through its long-standing engagement with Operation Clean Sweep® (OCS), a global initiative dedicated to preventing pellet loss. Borealis was the first polyolefins producer who carried out third-party external audits for OCS in its Kallo and Antwerp production locations in 2021, which served as pilot to help test pellet loss prevention standards and contributed to the establishment of an OCS third-party audit and certification scheme, launched in 2022.

In March 2025, Borealis successfully completed Operation Clean Sweep® (OCS) certification for all its polyolefin (PO) production locations, marking a significant milestone in our ongoing commitment to zero pellet loss. This achievement comes after more than six years of dedicated efforts and collaboration across the entire value chain.
