**1. Introduction**

Terminology of Geosynthetics is that "a planar product manufactured from polymeric material used with soil, rock, earth, or other geotechnical engineering related material as an integral part of a man-made project, structure, or system." Their functions of geosynthetics are shown in **Figure 1**, and polymeric materials for geosynthetics are shown in **Figure 2** [1–3].

Actually, polymeric materials for geosynthetics have their unique properties, and various additives are mixed to have the suitable and various functions of geosynthetics, and the manufacturing process is also different for each product. **Figures 2** and **3** show abbreviations and abbreviated definitions and examples of typical geosynthetic products, respectively.

Most of the geosynthetics contribute to the long-term stability of the soil structure, so that products with small changes in long-term performance are mainly used, while demand for biodegradable products emphasizing planting and environ-

strength retention rate should be within the given range during the service life.

Therefore, sustainable geosynthetics mentioned in this chapter are classified as "Usual Geosynthetics" and "Green Geosynthetics" based on required performance

First, environmental adaptive geosynthetics, which we have previously described as "Usual Geosynthetics," have not changed much over the past 20 years but have created a paradigm of composite products using extreme strength fibers with the keyword of diversification. The environmentally adaptable geosynthetics can be introduced as "Usual Geosynthetics," which are used to reinforce the ground structure, and the initial

In other words, usual geosynthetics are a product that requires a high resistance to instantaneous loads from the outside and also requires a hybrid function that converges to the reinforcement, protection, and blocking functions that are the basic functions of geotextiles. Since natural fibers have the advantage of being eco-friendly
