UBC Mining engineer and geologist Michael Hitch is studying the value of mine waste rock for its CO2-sequestration potential, or “SP.” He says mining companies across Canada will, in future, be able to offset CO2 emissions with “SP rock,” and within 25 years could even be selling emissions credits.
Hitch is working on this study with Greg Dipple and Ulrich Mayer of UBC’s Department of Earth, Ocean and Atmospheric Sciences, and Gordon Southam from the University of Western Ontario’s Department of Earth Science.
