Petroleum-based plastics have been causing severe ecological problems to the
environment, posing a threat to the marine life as well as the quality of air. A biodegradable bioplastic was produced using natural and biodegradable materials,
such as gelatin, glycerol, and water, together with natural agricultural wastes, such
as Jordanian olive tree leaves as reinforced fillers within the bioplastics. The study
aimed to investigate the type and percentage of each bioplastic component (biopolymer + plasticizer + other additive) and the influence of the percentage of the
olive leaves on the mechanical properties of the produced bioplastic. It was found
that, as the concentration of olive leaves increased, the density decreased; the
ductility also decreased down to 7 %, then increased.
