Edible, Ultrastrong, and Microplastic‐Free Bacterial Cellulose‐Based Straws by Biosynthesis
Summary
Researchers developed a new type of drinking straw made from bacterial cellulose that is edible, free of microplastics, and mechanically stronger than paper straws. The straw uses an alginate coating instead of adhesives and has a three-dimensional nanofiber structure that outperforms commercially available alternatives. This biosynthesized straw offers a healthier and more environmentally friendly replacement for disposable plastic straws.
Abstract The widespread use of disposable plastic straws cause serious environmental problems and poses potential threats to human health, while paper straws, their most used alternatives, are not so satisfactory due to poor mechanical performance and unpleasant user experience. Here, a new kind of edible and microplastic‐free straw made from bacterial cellulose (BC) by biosynthesis is reported. Through the alginate coating, this BC‐based straw achieves better mechanical performance than paper straws and avoids additional adhesives. Owing to the 3D nanofiber network and strong interlayer connection, the comprehensive performance of this BC‐based straw surpasses that of commercially available counterparts, satisfying the requirements for practical use. Of particular note, the edible character provides a better user experience and a new end‐of‐life option for the straws, making the BC‐based straw a healthier and more eco‐friendly substitute for plastic straws.
