Interfactory and Intrafactory Water Network System To Remodel a Conventional Industrial Park to a Green Eco-industrial Park

Abstract

Water network synthesis is to optimize a water supply system by connecting water sources to sinks in order to maximize water reuse. This synthesis has been applied within a factory to reduce freshwater Consumption. This study illustrates (i) the synthesis and design of an interfactory and intrafactory water network system for an eco-industrial park (EIPWNS) utilizing more opportunities for water reuse within an industrial park, and (ii) an environmental and economic feasibility Study to demonstrate benefits from industrial symbiosis. An EIPWNS is synthesized, designed, and compared to conventional water system (CWS). The feasibility Study using life cycle assessment and life cycle costing shows that the total environmental impacts of the EIPWNS are 7.5% to 16.0% less than those or the CWS, and the life cycle cost of the EIPWNS is 15.6% less. Therefore, the EIPWNS can be employed in remodeling a conventional industrial park to an eco-industrial park. This study provides a good example for disseminating EIPWNSs.
