Black BioStraws are made from 4-ply premium grade FSC™ (Forest Stewardship Council) Mix Certified Paper. An FSC™ certification confirms the forest is being managed in a way that preserves the natural ecosystem and benefits the lives of local people and workers, while also ensuring it remains economically viable. Black BioStraws are certified home compostable to European Standards (NF T51-800) – they can be thrown into a backyard compost bin after use. Each 7 x 210mm Black BioStraw is individually wrapped and delivered in a shelf-ready box with an inbuilt straw dispenser, offering easy access and hassle-free storage. Biopak paper straws have an indefinite shelf-life if kept cool and dry.
