如果在一个拥有数百万人口的城市地区，物质密集型企业共享本来可能被浪费的物质资源，会产生什么环境和公共利益？这项研究开发了一种基于生命周期评估工具的算法，用于确定一个城市的工业共生潜力-即一个城市的工业企业产生的废物和副产品的总和，这些废物和副产品可以合理地作为其他当地工业过程的资源投入。这项调查不是像以前的许多论文那样报告企业的私人收益，而是将当地企业可回收的最大资源量转换为对根据垃圾填埋场空间和水需求节约的市政基础设施容量的估计，从而关注城市的公共收益。这里的结果在印度Mysuru(Mysore)地区测试了这一新方法。我们发现，根据对1000家城市企业的投入和产出的分析，计算出的工业共生潜力相当于每天8.4万吨工业废物，大于7.4万吨CO(2)e，以及2200万升废水。这里介绍的方法展示了工业共生如何将私人生产和公共基础设施联系起来，通过创造机会来扩大公共基础设施的能力并产生公共卫生共同利益，从而提高城市的资源效率。
If the material intensive enterprises in an urban area of several million people shared physical resources that might otherwise be wasted, what environmental and public benefits would result? This study develops an algorithm based on lifecycle assessment tools for determining a city's industrial symbiosis potential-that is, the sum of the wastes and by products from a city's industrial enterprises that could reasonably serve as resource inputs to other local industrial processes. Rather than report, as do many previous papers, on private benefits to firms, this investigation focuses on public benefits to cities by converting the maximum quantity of resources recoverable by local enterprises into an estimate of the capacity of municipal infrastructure conserved in terms of landfill space and water demand. The results here test this novel approach for the district of Mysuru (Mysore), India. We find that the industrial symbiosis potential calculated based on analysis of the inputs and outputs of similar to 1000 urban enterprises, translates into 84 000 tons of industrial waste, greater than 74 000 tons of CO(2)e, and 22 million liters per day of wastewater. The method introduced here demonstrates how industrial symbiosis links private production and public infrastructure to improve the resource efficiency of a city by creating an opportunity to extend the capacity of public infrastructure and generate public health co-benefits.
