This product is manufactured with 100% Post Consumer Carpet. Every year approximately 4 Billion pounds of carpet are discarded into landfills. We believe that we can do our part to help our environment by keeping this material out of the landfills one disk at a time. ECO-disks Crpt are produced from 100% Post Consumer carpet that has been kept out of landfills. Each ECO-disk Crpt disk is produced from recycled high grade polypropylene polymer that is reusable, sturdy, but flexible and olive green in color. Every pound that can be utilized in our product line is not only benefiting gardeners abroad but also impacting our ecosystem.
