The natural fiber is considered recyclable and may have some potential for some application. Nowadays, this type of fiber has to gain popularity as a filler in polymer composites. Besides, it is readily available and environmentally friendly. It is also inexpensive because they are non-toxic and biodegradable waste. This paper presents the various natural fiber from fruit skin, fruit peel, agricultural residue, waste, and others as fillers in thermoplastic polyurethane (TPU). The author also reflects the key issue related to the effect of filler loading on the tensile properties of TPU composites. In general, the tensile strength of the natural fiber-filled polymer composites increases with fiber loading. The tensile properties are mainly influenced by the interfacial adhesion between the polymer and the fibers. Other than that, each type of fiber also plays a vital role in its properties and polymer adhesion. This review only focuses on the latest studies in the range of seven years from 2013 to 2019 [1].
