**Abstract**

Most of the geosynthetics contribute to the long-term stability of the soil structure, so products with little change in long-term performance are mainly used. To this end, demand for biodegradable products emphasizing planting and environmental compatibility is increasing. Sustainable geosynthetics can be categorized as "Usual Geosynthetics" and "Green Geosynthetics" on the basis of required performance, and it can be said that it is meaning to expand the use of geosynthetics in the fusion level. In here, "Usual Geosynthetics" refer to functional long-term maintenance and environmental adaptive products, and "Green Geosynthetics" refer to eco-environmental products that are decomposable geosynthetic fibers whose functions are extinguished after a required period of time. In this paper, we introduce sustainable geosynthetics, which are differentiated from raw materials to applicability.
