“…Results from this study indicate that ecological systems can provide services that mitigate all criteria air pollutants while being economically feasible. Similarly, Martinez-Hernandez et al 32,33 developed a framework that uses a systems dynamic approach to model techno-ecological interactions in a local heathland ecosystem in the UK. Halbe et al 31 used a functional organizational analysis method for designing a sustainable food supply system in Canada, allowing for consideration of both technical systems and ecosystem processes.…”

Despite the critical importance of ecological systems for sustaining all chemical and manufacturing processes, process design has kept nature outside its system boundary. Recent efforts for sustainable process design aim to reduce environmental impact, but no design method considers the capacity of ecosystems to supply the goods and services that are needed to sustain a process. Overcoming this deficiency of conventional process design is essential to transform the chemical industry into an activity that respects ecological constraints and results in a net positive societal impact. As an important step toward meeting this goal, this work expands the boundary of process design to include ecosystems as unit operations in traditional design. Similar to tasks performed by conventional unit operations, ecological processes perform ecosystem functions resulting in goods and services required by the technological system. The goal behind designing integrated techno‐ecological process flowsheets is to balance the ecosystem service demand of technological systems with the ecosystem service supply of ecological systems. Systems are optimized to balance the demand and supply subject to unit operation level constraints of technological and ecological systems, and interactions between detailed process level variables and ecological variables are explored. The Techno‐Ecological Synergy (TES) Design method is developed and applied to a biofuel production system, considering ecosystem services like water provisioning and water quality regulation provided by wetland ecosystems. Comparing the integrated TES design with conventional techno‐centric design shows that TES design can result in net positive impact manufacturing: a case where the ecosystem service supply is equal to or exceeds the demand, with little or no compromises in process profitability. These results should encourage close integration between technological and ecological systems while designing sustainable processes, and identify many challenges for developing TES of individual processes and across the life cycle. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2390–2407, 2018

“…It is also important to ensure technologies are implemented according to the capacity of local ecosystems [48] [49]. The local scale can also facilitate more opportunities for direct synergetic interactions, which can be facilitated by a framework that explicitly captures the dynamic nature of ecosystems as well as techno-ecological interactions in locally integrated production systems [50]. The design of local systems should also recognise the global planetary system as the ultimate boundary for process design by employing a process-to-planet framework [51].…”

Sustainability issues are changing the nature of process design problems and methods. • Design boundaries have expanded down towards molecular level and up to global scales. • Methods and decision support frameworks address multidimensionality and multiscale. • Explicit consideration of ecosystems has shown recent advancements. • Tools capturing the full range of scales and interactions are yet to be developed.

Life cycle assessment (LCA) has enabled consideration of environmental impacts beyond the narrow boundary of traditional engineering methods. This reduces the chance of shifting impacts outside the system boundary. However, sustainability also requires that supporting ecosystems are not adversely affected and remain capable of providing goods and services for supporting human activities. Conventional LCA does not account for this role of nature, and its metrics are best for comparing alternatives. These relative metrics do not provide information about absolute environmental sustainability, which requires comparison between the demand and supply of ecosystem services (ES). Technoecological synergy (TES) is a framework to account for ES, and has been demonstrated by application to systems such as buildings and manufacturing activities that have narrow system boundaries.This article develops an approach for techno-ecological synergy in life cycle assessment (TES-LCA) by expanding the steps in conventional LCA to incorporate the demand and supply of ecosystem goods and services at multiple spatial scales. This enables calculation of absolute environmental sustainability metrics, and helps identify opportunities for improving a life cycle not just by reducing impacts, but also by restoring and protecting ecosystems. TES-LCA of a biofuel life cycle demonstrates this approach by considering the ES of carbon sequestration, air quality regulation, and water provisioning. Results show that for the carbon sequestration ecosystem service, farming can be locally sustainable but unsustainable at the global or serviceshed scale. Air quality regulation is unsustainable at all scales, while water provisioning is sustainable at all scales for this study in the eastern part of the United States.
