The Effects of Olive Pomace Ash on The Color Change of The Composite Material and Its Mechanical Properties

Abstract

The purpose of this study is to apply olive pomace ash (Prina ash), which is the remainingpulp after the pressing of olives, to a plastic material. Prina particles transformed intothe 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 imagesand color change measurements were carried out with produced samples. The effects ofprina ash ratio on the color change and mechanical properties were investigated for theavailability of Prina. As a result, it was determined that an increase in prina ash ratio causedan increase in both color change and mechanical properties of the material.
