Associate Professor Matthew Oliver in the School of Economics and sixth-year Ph.D. student Archana Ghodeswar co-authored the article "Trading one Waste for Another? Unintended Consequences of fly ash Reuse in the Indian Electric Power Sector" in the journal Energy Policy. 

"In this paper, we examine the direct consequences of waste by-product reuse in a polluting industry, namely, India's coal-fired electric power sector, where ‘fly ash’ is legally required to be used as a substitute input in other industries," they wrote in the abstract. 

Oliver and Ghodeswar found that "these results suggest the potential benefits of this policy—e.g., reduced waste disposal costs—may be offset by unanticipated increases in other external costs, particularly if not accompanied by supplementary regulation of other forms of pollution."
