About Operation Clean Sweep
Operation Clean Sweep is a global program focused on preventing plastic pellet, flake, and powder loss, helping keep plastics out of waterways through best-practice guidelines, audits, and reporting.
Program Overview
Established in 1991 and administered by the Plastics Industry Association and the American Chemistry Council, Operation Clean Sweep provides tools and guidance for responsible plastics handling.
Best Practices & Guidance
The program publishes reports, audits, and guidelines to support practical improvements and reduce the risk of plastic material entering waterways.
Industry Commitment
Hundreds of plastics companies worldwide have signed the Operation Clean Sweep pledge to prevent resin loss during handling and operations.
Rosti’s Commitment
Rosti supports sustainability through waste reduction, improved recycling, and responsible operations in local communities—using programs like Operation Clean Sweep to strengthen environmental best practices.

Taking practical steps to eliminate pellet loss
Rosti is committed to helping improve the environment for future generations.
A kilogram of resin contains about 42,000 pellets, and Rosti uses around 55,000 tons of pellets every year, so being accountable for all the pellets we use requires a dedicated effort. One of the first steps we took was to make sure that every drain in each of our factories is fitted with steel mesh grids that prevent any loose pellets from washing into the water ecosystem. These drains are checked every week to make sure they are clear. If a significant number of pellets are found, then an investigation is conducted to find out the source, and corrective action is taken.
Education & Training
Our commitment to minimizing pellet loss is built on knowledge, responsibility, and consistent practices across all production sites worldwide.
Employee Training
Relevant employees across all facilities are trained to understand the importance of responsible handling of plastic resins and pellet loss prevention.
Partner & Contractor Training
Training is extended to external contractors, including drivers and distributors, to ensure environmentally sound procedures are followed throughout the entire value chain.
