Professor of Industrial Environmental Management, Director of the Center for Industrial Ecology, Director of the Program on Solid Waste Policy, and Director of the Industrial Environmental Management Program

Dr. Marian Chertow is Professor of Industrial Environmental Management and the Director of the Center for Industrial Ecology and at the Yale School of the Environment. She is also appointed at the Yale School of Management and the National University of Singapore. Her research and teaching focus on industrial ecology, business/environment issues, circular economy and waste management. Her research has championed the study of industrial symbiosis involving geographically based exchanges of materials, energy, water and wastes within networks of businesses globally. In 2019 she received the highest recognition of the International Society for Industrial Ecology, its Society Prize, for her “outstanding contributions to the field.”

Prior to Yale, Professor Chertow spent ten years in environmental business and state and local government including service as president of a bonding authority that built a billion dollars worth of waste infrastructure. She is a frequent international lecturer and became a Member of the Council of Canadian Academies (CCA) Expert Panel on Circular Economy in Canada in 2020. She also serves as an Advisor to the Center for Energy Efficiency and Sustainability at Trane Technologies, Inc, is on the Board of Terracycle US Inc, and the Steering Committee of the Alliance for Research in Corporate Sustainability.

Thomas Graedel

Clifton R. Musser Professor Emeritus of Industrial Ecology, Professor Emeritus of Chemical Engineering

Thomas Graedel is the Clifton R. Musser Professor Emeritus of Industrial Ecology. His research is centered on developing and enhancing industrial ecology, the organizing framework for the study of the interactions of modern technological society with the environment. The co-author of the first textbook on the subject (Industrial Ecology, Prentice Hall, 1995), he has since continued to contribute to the field with numerous books and scholarly articles and has been recognized with several significant awards. His latest book, Industrial Ecology and Sustainability, co-authored with Professor Matthew Eckelman, was published in 2023. His environmental assessment matrix, developed during a 27-year career with AT&T Bell Laboratories, is now a standard industrial tool for streamlined life-cycle assessments of the environmental attributes of products, processes, and facilities. He was elected to the US National Academy of Engineering in 2002 for “outstanding contributions to the theory and practice of industrial ecology.”
