In this research, the effect of adding a pine cone on some properties of polypropylene and the effect of treating the additive with no water of malic acid on the studied properties was studied, and the pinecone was added at (5,10,15,20,25)% ratios, and we found that it is the best ratio to achieve Good properties are 15% when bending resistance is tested, and at the rest of the tests, the properties increased by increasing the percentage of the additive, so 15% of the additive was chosen, not usually the tests, but after treating the pine cone with no water, malic acid was added in proportions (1,3,5, 7)% and we found that the value of the studied properties increased after treatment with no maleic acid water of the substance added from it before treatment and that at the rates of 5% of without maleic acid water the value of the studied properties was higher than the rest of the percentages.
