The purpose of this study is to apply olive pomace ash (Prina ash), which is the remaining pulp after the pressing of olives, to a plastic material. Prina particles transformed into the ash were mixed in Polypropylene (PP) polymer with a weight ratio of 0%, 1% and 3% and then molded in the injection machine. Tensile-Stress Test, impact test, SEM images and color change measurements were carried out with produced samples. The effects of prina ash ratio on the color change and mechanical properties were investigated for the availability of Prina. As a result, it was determined that an increase in prina ash ratio caused an increase in both color change and mechanical properties of the material.
