Analyses of the environmental impacts of an eco-industrial park using fuzzy cognitive maps

This paper presents the application of fuzzy cognitive mapping analysis to study the impacts of developing an eco-industrial park (EIP). Within an EIP, one facility´s waste is used as another´s input, thereby reducing raw materials required and waste generated. While this is beneficial from a waste reduction approach, there are other factors such as colocation of secondary and tertiary services, increased population and vehicular traffic that follows as more industries colocate within a geographical area, which need to be considered. The combined impact on all these indirect effects has been studied here using a fuzzy cognitive map. The impact assessment found that utilizing byproducts/wastes provided by existing facilities significantly decreases waste disposal, but may lead to increased pollution due to increased activity level as additional businesses are established.
