What antimicrobial agents are added to WPC to inhibit bacterial growth in outdoor trash cans?

To inhibit bacterial growth in outdoor trash cans made from Wood Plastic Composite (WPC), specific antimicrobial agents are incorporated directly into the material during the manufacturing process. The most common agents used are silver-based ions (e.g., silver zirconium phosphate), zinc oxide, and sometimes triclosan. These additives work by disrupting the cellular functions of microorganisms, preventing them from reproducing and forming colonies on the surface of the trash can. By being embedded within the WPC material, these agents provide long-lasting protection without washing away, making outdoor trash cans more hygienic, reducing odors, and minimizing surface degradation caused by microbial activity. This integration is a key advantage of WPC for outdoor applications where moisture and organic waste can promote rapid bacterial growth.
