Abstract: There is disclosed a process and product made by said process, for conversion of organic waste sludges bearing potentially pathogenic bacteria, helminth ova and enteric virus into a non-odoriferous, non-pathogenic agricultural medium which is highly nutritious to plant life; which process includes: disinfecting the sludge by thoroughly mixing the organic sludge with an effective amount of at least one of a class of chemical compounds which form methyl-isothiocyanate ("MITC"), such as sodium N-methyldithiocarbamate in aqueous solution and increasing the pH of the sludge to substantially 12 or more for an effective length of time; and, conditioning the disinfected sludge with electrolytic soil additive, hydrophilic polymer, organic bulking agents and/or inorganic conditioning materials. The product of said process constitutes a composition highly beneficial as a plant growing medium, soil enriching additive and the like.
