Upon submission for publication of our paper on “Industrial Ecology for Leverage to Loose Less Cadmium,” we post our simulator of cadmium flows to our ImPACT identity site. The “DynaCad” simulator provides the basis for key conclusions in the paper. We thank Paul Waggoner for his lead role in creating the simulator and Iddo Wernick, Peter Elias,
and Tony Barrett for their patience in completing this work, which grew out of our 1997 report Industrial Ecology: Some Directions for Research.
