The environmental impact assessment of energy intensive industries in Markazi province by RIAM fuzzy
Energy intensive industries cause serious impacts on the surrounding environment. Therefore, in these sorts of projects, environmental impact assessment of energy intensive industries is one of the most important aspects of environmental management. The objective of present research is using one of the environmental impact assessment methods to make the managerial decisions for determining the most important identified impacts and impacts occurring prevention or reduction.
The environmental impact assessment of energy intensive industries, which is located on Steel, aluminum, cement and petrochemical industry in Markazi province, were investigated. Firstly, environmental impacts were identified using Delphi questionnaire method and based on their criteria including physical-chemical, economic and functional, Bio ecological and socio-cultural. Then the aforementioned criteria of impacts were assessed by using RIAM Fuzzy method.
The results show that most severe negative impacts (- E) and significantly (- D) for energy intensive industries are as following: aluminum, petrochemical, steel and cement. The results show that the most important impacts of energy intensive industries are respectively including air quality and air pollutant emissions(physical-chemical), changes in species diversity and density (Bio ecological), create job opportunities (economic and functional) and changes in demographic patterns (socio-cultural).
All energy intensive industries have significant effects on the environment of Markazi provinces and the RIAM Fuzzy method is suitable for reducing uncertainties in the environmental impact assessment of energy intensive industries.
