Biofiber (BF)-based polymer composites have huge impact globally due to sustainability along with renewability effect. Over the past few decades, BFs such as bamboo, kenaf, cotton, jute, and so on have been well investigated with a several composite approach. Numerous research works have been done on the potentiality of BF-based reinforced composites. Besides, several critical advanced applications are also explored using these composites. Thus the demand for such composites is growing faster. This review targets to sum up the recent advances and applications of BF-based polymer composites, which is crucial for researchers and manufacturing engineers as well as to continue the use of green composites in the future.
