Abstract
Presents an MINLP model to design an eco-industrial plant by retrofitting existing water networks from a number plants located in the same industrial zone. The model is based on a superstructure. 
It takes into account both in-plant and inter-plant structural modifications, including placement/reassignment of existing treatment units, required increase of capacity and/or efficiency of existing treatment units, placement of new treatment units either within participating plants or in a new shared wastewater treatment facility, and stream re-piping associated with installing new treatment units and retrofitting existing treatment units.
