The Australian Industrial Ecology Network (AIEN) is a vibrant network of like-minded individuals, companies and institutions with a common interest in sustainable development through the study and practice of industrial ecology. We advocate the principles and concepts of industrial ecology in policy formation and business practice. The AIEN actively engages with organisations to facilitate improved performance and environmental benefits. The AIEN is also a forum in which people can discuss ideas, seek advice from one another or simply keep in touch through the network with developments and best practice in their particular areas of interest.
