Items in the Anno Recycled collection are made of GRS certified recycled materials. The Global Recycled Standard (GRS) is a voluntary product standard for tracking and verifying the content of recycled materials in a final product. GRS covers processing, manufacturing, packaging, labeling, trading and distribution of all products made with a minimum of 20% recycled material. It also sets requirements for third-party certification of recycled content, chain of custody, social and environmental practices, and chemical restrictions.
