We choose to use #5 plastic (polypropylene) as our source material because it is a versatile and benign plastic. Preserve obtains our recycled plastics from a network of trusted sourcing partners and we test each new source that we reprocess. The recycled plastic in our Preserve products represents pre-consumer recycled material or a mixture of pre- and post-consumer blends.
We identify the origins and intended use of all our plastics and work with our material suppliers to ensure that we know the first application of each material source. We follow FDA guidelines for use of post-consumer plastics in our products and all our sources of recycled plastic are tested for foreign elements, such as heavy metals, to ensure that there are no harmful chemicals migrating from the plastics that we use.
