摘要

A staggering 350 million metric tonnes of plastic waste is generated globally every year, which is a matter of prime concern. Moreover, about 1300 million tonnes of agricultural waste is generated per year in the world. In this study, efforts have been made to address these issues by developing a biodegradable composite using banana tree waste and refined wheat flour with water as a plasticizing agent. Two different fiber types (banana scutcher and banana dried leaf), and three fiber loading percentages (45%, 50%, and 60%) were used for developing composite boards. The compression molding technique is used to develop a composite. The developed composite material is characterized by flexural strength, hardness, degradation, water absorption behavior, color, and density. Banana pseudostem fiber (scutcher) incorporated composite board in the fiber loading percentage of 45% gave maximum flexural strength (12.59 MPa) and hardness (64.5 HD). The maximum degradation in terms of weight loss percentage (87–89%) was found in the sample incorporated with dried banana leaf in the fiber loading percentage of 60%. All composites exhibited high water absorption with a minimum water absorption percentage (117.38%) shown by the banana dried leaf-based composite in the fiber loading percentage of 45%. The average density of all the composites ranges between 850 and 1200 kg/m3.
