Due to the fact that natural biomaterials are becoming more and more interesting, they are environmentally friendly, have higher biocompatibility, and cost less. Extraction of natural Calcium carbonate from eggshells was studied using calcination process at 250c, as a reinforcement added to aloe Vera gel with alginate to prepare Natural Hybrid composite matrix (aloe Vera+alginate+ Calcium carbonate). The results showed extracted Calcium carbonate is of high purity and no impurities were resulting from the calcination process, as no secondary compounds appeared and that the ratios of Natural Hybrid composite matrix formation were appropriate and the sustainable mixing method was correct, as it did not affect the main peaks. And the parameter used in the calcination process is very successful and high crystallinity of Calcium carbonate was obtained. In addition, the polymeric additives did not affect the crystallinity and purity of Calcium carbonate, but on the contrary, increased the purity of the material and a uniform structure was obtained. Also, the extracted Calcium carbonate has a regular crystal structure, which indicates the success of the calcination process well, in addition to the fact that a Nano-granular size was obtained. The distribution of Calcium carbonate particles within the polymer was uniform and homogeneous. The Natural Hybrid composite matrixproved that it can inhibit some types of bacteria and fungi, but failed against others.
