The present study intends to examine the links between industrial gross domestic product, skilled labor, invested capital and finished products for Tunisian Company of Lubricants on a temporal model over the 1980-2017 periods. Indeed, we demonstrate that the policy maker using capital and labor is essential to raise the industrial gross domestic product for this manufacturing sector by producing secondary materials and improving research activity. Our results imply that there is a great relationship among these variable, as a consequence of the benefits for re-refining used lube oil in economic growth of Tunisia. Finally, we find that our analytical framework is compliant with the empirical results.
