Amid growing piles of plastic waste in our landfills and in our oceans, Dr. Michael McGuirk of the Colorado School of Mines and the National Renewable Energy Laboratory (NREL) is working on new methods to recycle plastics and turn them into useful products, from new plastics to fuels to polymers that can capture CO2 from the atmosphere and help ease global climate change. 

His optimism about his research is tempered by the fact that he's worried by the current cutbacks in government research funds. His talk was recorded before a live audience at the Telluride Mountain Village Conference Center with veteran journalists Judy Muller and George Lewis moderating.
