通过将生态系统纳入工艺设计，有可能在技术和生态系统之间发展协同作用，以建立环境可持续性的孤岛。这种办法还可以确保人类活动不会使生态系统退化--生态系统对我们的可持续性至关重要。这项工作评估了将生态系统作为单元操作纳入工艺设计的想法[1]，同时考虑了生态系统的间歇性和生长。选择性催化还原(SCR)技术和森林生态系统都能够减少二氧化氮(NO2)的排放，并旨在支持德克萨斯州加尔维斯顿附近的氯碱工艺。研究发现，森林生态系统的成本占到了SCR成本的四分之一。然而，由于植物吸收排放的能力随着季节的变化而变化，氯碱工艺需要相应地调整其生产率。这种适应当地生态系统的结果可能是制造业实现净零排放，并朝着环境可持续发展迈出一步。这项研究表明，需要进行进一步的研究，以解决工业和生态系统的实践和理论方面的问题，以建立在经济、生态和社会上可行的互惠关系。
By including ecosystems in process design, it becomes possible to develop synergies between technological and ecological systems to establish islands of environmental sustainability. Such an approach can also ensure that human activities do not degrade ecosystems—the very systems that are essential for our sustainability. This work evaluates the idea of including ecosystems as unit operations in process design [1] while accounting for the intermittency and growth of ecological systems. The technology of selective catalytic reduction (SCR) and a forest ecosystem are both capable of mitigating nitrogen dioxide (NO2) emissions and are designed to support a chloralkali process near Galveston, Texas. The cost of the forest ecosystem taking up NO2is found to be one‐fourth of the cost of the SCR. However, as the capacity of vegetation to take up emissions varies with seasons, the chloralkali process needs to adjust its manufacturing rate accordingly. The result of such adaptation to local ecosystems can be manufacturing with net zero emissions and a step toward environmental sustainability. This study demonstrates the need for further research to address the practical and theoretical aspects of industry and ecosystems to establish mutually beneficial relationships that are economically, ecologically, and societally viable.
