This research study of xrd characterization analysis of organic filler comprise waste banana peel and waste egg shell as matrix and reinforcement in bio-composite thin film. Banana peel fibers exhibit good renewable material for the substitution of bio based composite. The banana peel and egg shell were separately cut into smaller pieces and boiled for 20 min before drying in oven at temperature 80 ˚C for 30 min. These pieces were then ground using mechanical blender into fine powder sizes ranging from 80 -100 µm,. This bio-composite thin film will investigate by using X-ray diffraction (XRD) analysis to determine of crystallinity of a compound, distinguishing between amorphous and crystalline material and to quantification of the percent crystalline of a bio-composite thin film. shows that the sharp peaks on egg shell graph at 2Ɵ = 28˚ and 42˚which represent the CaCO3 and it has high crystallinity degree which is 82.9% compared to banana peel.

INTRODUCTION Vast amounts of food waste around the world can cause significant health and environmental problems that ultimately lead to economic world. However, most food wastes contain valuable minerals that could serve as raw materials for the production of glass, ceramics, and glass-ceramics. Organic waste typically has value in terms of energy, water content, and mineral content, but current methods of waste disposal do not utilize these resources. Instead, communities incur costs to store synthetic plastic thin film in landfills, where it emits uncontrolled greenhouse gasses and poses risks to pollution. Recent government regulations regarding landfills, for example, those in Europe,lead to a direct economic stimulus to create value out of waste. Solutions to reduce the mass of landfills could be coupled with extraction of the resources they contain. Banana peel is a waste material with rich of starch. This characteristic makes them potential to produce bio- polymer thin film which is more environmentally friendly due to its biodegradable abilities compared to the conventional synthetic petroleum-polymer. In addition, banana peels are agricultural waste that discarded as useless material. This waste contributed to waste management problems although they have some compost
