Abstract (en)
[origin: WO2012146847A1] The invention relates to a nonwoven geotextile comprising: crushed plant stems (305) having a diameter of more than 5 mm, plant stem fragments (310), and plant fibers (315) partially attached to the crushed stems, wherein the plant stems and the plant stem fragments are interwoven by means of mechanical connections produced by spraying water. In preferred embodiments, the plants comprise hemp. The device for producing such a nonwoven geotextile comprises: a means for arranging plants in a sheet comprising crushed plant stems having a diameter of more than 5 mm, plant stem fragments and plant fibers partially attached to the crushed stems; and a means for spraying water onto said sheet so as to form mechanical connections between the crushed plant stems, the plant stem fragments and the plant fibers of the sheet.
