Ariana led a project with collaborators from the Yale Center for Industrial Ecology, the Resource Optimization Initiative, and the Illinois Institute of Technology to study the industrial system in Nanjangud, India from 2008-2012.
It quantified and mapped the material, energy, and water flows and social patterns of 45 diverse industrial facilities alongside gathering and analyzing the network of between key managers at each company. The project was the first of its kind in India and the second in the world.
The results found a recycling and reuse rate of 99.5% of the nearly 900,000 metric tons of annual wastes as well as shared mental norms between managers at facilities that engaged in trading wastes for reuse. Additional research conducted a consequential life cycle inventory of greenhouse gas emissions and social impacts created by future waste-to-energy opportunities.
In addition to publication, results from this project were presented at the 2009 and 2011 conferences of the International Society for Industrial Ecology and the 2009 Next Generation Infrastructure conference.
