Waste cigarette butts fiber (CBS) was used and recycled by reinforcing it with unsaturated polyester resin (UPE). It was used to obtain structural sections at a low cost and eliminate the environmental pollution risks resulting from these wastes (CBS). Samples were prepared by manual casting according to the mass fractions (0%, 2%, 4%, 6%, 8%,10%) of cigarette butt fibers (CBS). The prepared samples carried out mechanical tests (hardness, bending, and tensile elastic modulus). The results showed that the modulus of elasticity and bending resistance increased with the increase of the weight ratio and that these values were directly proportional to the increase in the amount of reinforcement from the CBS fibers.
