The latest progress reported in thequest for a toxic waste-free environment comes from researchers at theCalifornia Institute of Technologyin Pasadena, US (AlternativesJournal. Vo122. No 1).
Chemist Michael Hoffman andhis colleagues have used high frequency ultrasound waves to breakdown samples of several toxic chemicals. Tiny bubbles form whenultrasound is directed at liquids andcollapse just as rapidly. With internal temperatures rising to 5.500C,the complex toxic molecules breakdown into non hazardous components.
