Yes. CSI’s closure products are recyclable. Because many of our two piece closures are made of more than one material, and given the strict FDA and other governmental approvals required for recycled materials, the caps are often recycled into non-food contact applications rather than direct food contact applications. The recycling resin identifier code varies depending on the raw materials used to make specific closure profiles. For instance, the recycling code for Polypropylene is 5, while the code for HDPE is 2.
CSI encourages consumers to replace the cap on the bottle prior to recycling, as municipal recycling centers sometimes do not want to process single closures. Recycling of closures often occurs as a result of the bottle recycling process, which is why it is important to make sure the closures are placed back on the bottles prior to recycling.
