Processes for the treatment of toxic and malodorous wastestreams produced in the manufacture of methomyl and related compounds are provided. In these processes, methomyl and related compounds are oxidized with chlorine at a temperature of at least about 70 DEG C., preferably in the range of about 70 DEG -95 DEG C., preferably under acidic conditions, and then the resulting intermediate compounds are hydrolyzed with NaOH, KOH or Ca(OH)2 at a temperature of at least about 70 DEG C., preferably in the range of about 70 DEG -100 DEG C., and at a reaction medium pH of at least about 9.5. The process is preferably carried out continuously.
