Not sure what is meant exactly by “Sustainable Industrial Practices” but it sounds like just a compilation of best practices for sustainable management, while industrial ecology is more of a science and engineering practice that is primarily focused on analysing and designing the material and energy flows within our industrial systems so as to better integrate them with natural processes – build circler economies and reduce negative externalities. For me this is the best definition from Indigo Development: “Industrial ecology is an interdisciplinary framework for designing and operating industrial systems as living systems interdependent with natural systems. It seeks to balance environmental and economic performance within emerging understanding of local and global ecological constraints. Some of its developers have called it the science of sustainability”
