防止和限制颗粒、碎片和粉末流失是塑料行业的首要任务，也是我们面临的重大环境问题。 Reportedly, each year roughly 100 million spilled pellets enter the environment, making their way into local waterways and eventually into estuaries and oceans. Not only is this a litter issue, but these pellets, flakes, and powders can harm birds or marine animals.
Operation Clean Sweep® (OCS), is a plastics industry association effort to reduce plastic pellets in the environment. The program helps companies and their facilities implement good housekeeping through pellet, flake, and powder containment practices and to work toward achieving zero pellet, flake, and powder loss — thereby protecting the environment and saving valuable resources.
Trinseo, as well as a number of other industry partners, has been an active member of OCS and has signed a “Pledge to Prevent Resin Pellet Loss”. The first step – which is truly ongoing -- is to conduct in-depth assessments of each facility’s level of implementation of the OCS program.
Pellet, flake and powder loss has many negative impacts on individual companies, on the plastics industry as a whole and on the environment. According to ONS:
The organization states that when the industry handles pellets, flakes and powder as responsibility as possible:
