Abstract
In order to form a recycling-oriented society, workshops, industrial parks and metropolis are the important elements. Therefore, industrial symbiosis model attracts more and more attentions nowadays.Base on the concept of industrial symbiosis model, YUCHUAN Circular Economy Industrial Park has been constructed. It recovers waste such as construction waste, sewage sludge and stone charcoal produced by the thermal power station within and surrounding Tianjin city and replace them respectively with mortar and reuse them as concrete vesicant and fertilizer. Furthermore, symbiosis model has been set up for company to company. Sewage treatment plant and building materials manufacturing plant utilizing the residual heat produced by the thermal power station. Instead, the thermal power station utilizing the sewage water as cooling water. In that, the resources and energy consumption efficiency of the industrial park, has been improved.
This research takes Tianjin city as a regional example, case studying the YUCHUAN Circular Economy Industrial Park, and conduct quantitative evaluation, utilizing LCA methodologies, towards industrial symbiosis model's environmental load reduction, comparing it to the status of waste disposal.And the result shows that environmental impact of CO2 emissions of industrial symbiosis model is much small.
