Abstract:
... Substance flow analysis on the industrial park scale is confounded by the multiple sources of inputs and outputs involving raw materials, products, and emissions, and by complicated intra-firm and inter-firm flows. As a result, substance flow analysis is less frequently applied than bulk material flow analysis in the planning and implementation of eco-industrial parks. The research aims to fill th ...
