Can we use sound to eliminate toxic waste? Maybe play The Sound of Music to neutralize it? lol Well...it looks like it is a real possibility. Neutralize nuclear waste? Why not? If sound can affect molecular bonds.....

The heat energy unleashed by cavitation breaks down the bonds that tie large molecules together, such as the perfluoroalkyl sulfonates and carboxylates, or PFCs, found in fire-fighting foams. These toxic PFCs are hard to break down and tend to persist in the environment, and in body tissue, which is why the Air Force will be investigating cavitation as a cost-effective method of producing temperatures in excess of 10,000 degrees Fahrenheit, more than enough to incinerate the problem chemicals.
