Green Straw Lepironia has the potential to be a green straw or zero waste drinking straw: in Vietnam and Indonesia, the process of producing straws is not difficult, merely cleaning the stems of plants and allowing them to dry in the sun. Lepironia straws offer a solution for the dilemma of using plastic straws.
