CLEANER CHEMICAL PROCESSES

Principles and methods for the development of cleaner chemical process es are discussed. The major part of the paper is dedicated to the deve lopment of ecologically more compatible waste treatment/disposal proce sses. Supercritical fluids as reaction media and as separation solvent s and the application of indirect electroredox processes have been sel ected for process development. The R&D activities described in the pap er include the cleaning of contaminated aqueous effluents by supercrit ical oxidation and of liquid effluents and solids by supercritical ext raction as well as the electrochemical destruction of organic pollutan ts.
