METHOD FOR NON-STANDARD PESTICIDES DISPOSAL Russian patent published in 2009 - IPC A62D3/00 A62D3/11 A62D3/35 A62D101/04 

FIELD: chemistry.

SUBSTANCE: method for non-standard pesticides disposal includes two stages wherein on the first stage the pesticides are destructed by hydrolysis in aqueous alkali medium at pH 13-14; on the second stage the obtained hydrolysate is processed in electrocoagulator with soluble iron electrodes at pH 9-10 and at saturation of the electrolyte with air oxygen up to the concentration 2-6 mg/l. If the pesticide commodity form is solvent or emulsion they are hydrolysed at boiling temperature of the solvent up to its complete distillation from the aqueous alkali solution If the pesticide commodity form is powder or pellets they are hydrolyzed at the boiling of the alkali solution during 0.5 hrs. The electro coagulation products are removed by settling and filtration of the alkali solution through the inert filter media with following recycling of the alkali solution.

EFFECT: environmentally safe disposal of the most part of the non-standard pesticides in any commodity form providing decrease of operating costs and recycling of the recoverable resources.
