**4. Conclusions**

Polysaccharide‐based composites are attractive biomaterials because of their chemical structure and ease of manipulation. They are easily processable and abundant in nature, forming a vast potential economical application compared to other synthetic biomaterials. Moreover, they are highly environmental friendly and nontoxic to humans and animals. Preserving the nature while taking advantage of its application leads to promising future for renewable and sustainable materials. Polysaccharide‐based composites are mainly to over‐ come the problem of low mechanical and water barrier properties of common natural poly‐ mers. Many studies have been done and successfully associated different reinforcements and fillers to polysaccharides for variety of fabrication purposes. Polysaccharide‐based composites are thus a favorable alternative to the commercial petroleum‐based polymers and highly recommended for renewable and sustainable composite materials.
