Due to factors such as political issues, technological change and natural disasters as well as the spread of environmental concerns and social responsibility, supply chain issues are no longer just a matter of looking ahead but the reverse-processing is also a matter of consideration. For this purpose, the present paper deals with the design and modeling of multi-periodic and multi-product green closed-loop supply chain in olive production. After designing the supply chain, the optimization of the whole chain profit and costs of the pollutants from the olive-product-processing process was investigated using a Genetic Algorithm based on Iranian olive data during the years 2016 to 2018. The model also came closer to reality by incorporating risk into the proposed model and taking into account the demand of all centers under risk conditions. The results show that the chain is profitable at 55417 billion Riyals, but with respect to the waste disposal to waste recycling cost-benefit ratio, 431.91, Iran's olive supply chain performs poorly in waste recycling, which by incorporating this model and revising the chain, this ratio will be reduced by 79%. Furthermore, according to the results, there is no need for import in risky conditions and all the market’s demand and export centers demand is met without any lost sales by the chain itself. It is, therefore, suggested to increase productivity in the field of olive-conversion-industries by equipping olive processing plants and constructing oil-production waste processing plants. On the other hand, in spite of the potentials and capacity of olive production and processing, it is suggested that macro-level policies be adopted to increase the consumption of olive oil in order to promote community health and create added value in order to increase the production of these products compared to its present value.
