In the last decades, the urban growth of developed countries has caused several environmental, social and economic problems, such as the inefficient use of resources and infrastructures. Notwithstanding, detailed analysis of population＇s necessities allows decreasing these drawbacks. These enhancements can foster a more feasible development through technical sustainability criteria. Therefore, the urban metabolism study becomes an essential tool to plan a suitable management for material and energy flows. Industrial Ecology （IE） theory looks for the sustainable integration of human activities on their natural environment. It seeks mimic natural systems performance and their processes. Industrial Metabolism （IM） studies those processes which turns material and energy into products and wastes. The IE final goals aim to promote improvements in process efficiency, decreasing consumption and waste generation through flows recirculation and exchange networks of material and energy. This contribution proposes a new conceptual framework which integrates urban and industrial metabolisms as an opportunity to achieve more efficient and sustainable development. The review of national and international experiences shows the improvements achieved through metabolisms＇ combination based on the exchanges of residual energy and water streams.展开更多

In this paper, we trace the development history of industrial symbiosis, and review its current theoretical and methodological bases, as well as trends in current research. Based on the research gaps that we identify, we provide suggestions to guide the future development of this approach to permit more comprehensive analyses. Our theoretical review includes key definitions, a classification system, and a description of the formation and development mechanisms. We discuss methodological studies from the perspective of individual industrial metabolic processes and network analysis. Analyzing specific metabolic processes can help to characterize the exchanges of materials and energy, and to reveal the ecological performance and economic benefits of the symbiosis. Network analysis methods are increasingly being used to analyze both the structural and functional characteristics of a system. Our suggestions for future research focus on three aspects： how to quantitatively classify industrial symbiosis systems, monitor the dynamics of a developing industrial symbiosis system, and analyze its internal attributes more deeply.展开更多
