Sustainable Industrial-Natural Coupled Systems (SINCS)

Our work is currently supported by NSF CBET.

Welcome to Sustainable Industrial Natural Coupled Systems (SINCS) Group. The mission of SINCS group is to enable sustainable growth of biobased economy and industries along with ensuring local and global ecological sustainability. Dr Shweta Singh is the PI of SINCS and her vision is to enable a synergy between industrial and natural systems that aligns with the Industrial Ecology and Sustainable Engineering vision.

SINCS is an interdisciplinary group and resides in Department of Agricultural & Biological Engineering and Environmental and Ecological Engineering at Purdue University. Our research interests lie in Sustainability Engineering focusing on developing mathematical models for physical coupling of industries with natural systems through complex systems modeling approaches. To accomplish this vision we integrate process systems engineering models with macroeconomic models and utilize the methods of machine learning to provide insights into interface of engineering and economy. We also analyze the environmental implications of these changes through emissions and resource consumption to inform adoption of sustainable technologies.
