In this paper, we propose the adoption of industrial symbiosis approach within cities as a tool to improve their environmental sustainability. In particular, organic waste can be used to produce electric energy required by cities. In this way, a resource closed loop is generated, able to reduce the amount of waste disposed of in landfill and the energy purchased from outside the city. We develop a conceptual model that identifies symbiotic flows and processes that generate and receive them. We model these processes using the input-output approach. An efficiency measure of the symbiotic approach within urban areas has been proposed. Finally, we employ three case examples in order to show how the model works. As a result, we provide some useful managerial suggestions for policy makers about the implementation of industrial symbiosis within cities.

Abstract
In this paper, we propose the adoption of industrial symbiosis approach within cities as a tool to improve their environmental sustainability. In particular, organic waste can be used to produce electric energy required by cities. In this way, a resource closed loop is generated, able to reduce the amount of waste disposed of in landfill and the energy purchased from outside the city. We develop a conceptual model that identifies symbiotic flows and processes that generate and receive them. We model these processes using the input-output approach. An efficiency measure of the symbiotic approach within urban areas has been proposed. Finally, we employ three case examples in order to show how the model works. As a result, we provide some useful managerial suggestions for policy makers about the implementation of industrial symbiosis within cities.File | Dimensione | Formato | |
