If ultrasound could be used to reduce rubbish down to basic chemical elements then it will cause a major chemical hazard that would need to be dealt with (called rubbish). Also the fuel needed to power the ultrasound will cause the production of rubbish! Sadly, the Laws of Thermodynamics will always be out to get yer!
