Fiber orientation plays a major role in controlling the mechanical properties of natural fiber bio composites. An investigation into the impact of fiber direction variations on the toughness and tensile strength of burlap waste composites for automobile bumpers was carried out. This research was designed as a controlled experimental investigation. The factors evaluated were fiber orientation, while the tensile strength and impact toughness were. Bio composites were manufactured utilizing the hand lay-up procedure, and mechanical testing included tensile (ASTM D638) and impact (ASTM 4812). The number of test replications was fixed at three specimens for each variable. By improving interfacial adhesion, the 0°/+90°/0°/+90°/0° fiber orientation produces a tensile strength of 21.087 N/mm² and an impact toughness of 0.0482 J/mm², which is higher than a car bumper. These research show proof that burlap sack waste-based composites can be used as an alternative material for environmentally acceptable and sustainable bumpers. These findings complement SDG 12, which focuses on responsible production and consumption.
