phade compostable straws help humans reduce our plastic footprint - an estimated 5000,000,000 straws per day. One small change can help make a big impact. Polyhydroxyalkanoate (PHA), biopolymer derived from canola oil, keeps straws sturdy in drinks before safely returning to the Earth after use - centuries faster than traditional plastic. Universal fit lets you use straws in most types of cups and cup sizes and work ideally in cold beverages. Packaging comes boxed for countertop use. Straws are certified industrial compostable by BPI and TUV and certified home compostable by TUV.
