In the challenge of chemical production, management will be successful if it has production waste and by-products in terms of mass and finance. The new method of material flow costing (MFCA) is using green productivity tools, which increases productivity with a mass and financial approach and increasing efficiency. This method saves money by initially identifying and then providing a scientific and practical way to prevent material loss (waste), energy, costs and CO2 emissions. To achieve this goal, MFCA can be used to calculate the true costs of losses (hidden costs). Therefore, the purpose of this study is the production wastes in the olefin unit of a petrochemical company in the south of Iran and the cost characteristics of these wastes using the MFCA tool. Also, methodological solutions to reduce these wastes and increase productivity in this industrial unit have been presented. Based on the application of productivity improvement strategies, a 40% reduction in coke waste and a 10% increase in ethylene production are predicted in the process.
