Environmental risk assessment of Shohadaye Khalij Fars Agro-industrial Complex Using TOPEFMEA method

This study was conducted with the aim of environmental risk assessment of Shohadaye Khalij Fars Agro-industrial Complex situated in kilometer 75 of Ahvaz - Khorramshahr Road. In this paper, after reviewing activities, measuring contamination parameters and processes of sugar production salon of the Complex, environmental risk assessment was performed via TOPMEFEA. This is a hybrid method for the environmental risk assessment which is composed of a combination of the two methods of TOPSIS and EFMEA. For this purpose, in accordance with the method of analysis of failure modes and its impacts on the environment, some worksheets were first designed to assess the environmental risks. In these worksheets, variables such as the identification process of potential failure modes, potential effects of failures, potential causes of failure, initial assessment of the environmental aspects, were studied as environmental aspects. Then, using brainstorming method environmental impacts of each activity were identified and evaluated by relevant personnel and experts. The results showed the entry of contaminants and chemicals to aquatic environment due to sugar production process with the risk priority number of 16 with first priority, and the entry of chemical compounds and carbohydrates into the aquatic environment due to syrup refining, and contaminates. Considering that drainage in this Complex will have the most significant outcomes, the establishment of an industrial refinery and the application of advanced methods of wastewater treatment were among the proposals to reduce the most important risk factors.
