This paper explores the impact of synthetic gypsum, a byproduct of sulfur dioxide (SO2) abatement, on the technical efficiency of SO2 scrubber technology. On average SO2 scrubbers are 60% efficient suggesting substantial emission reductions are possible by narrowing the efficiency gap. Gypsum marketability provides an economic incentive for improved power-plant operation of scrubbers with 8.8% average increases in technical efficiency. By contrast, we do not find any statistically significant evidence of innovative change in scrubbing technology.
