    Abstract: A method for the processing of fecal waste by treatment with mineral clay, characterized in that:A. a smectite clay, enriched with aerobic and anaerobic microorganisms, specific for the digestion of fecal waste, and with plant preparations which promote the increase of said microorganisms, and lime, is allowed to digest the fecal waste; andB. an acid phosphate is added to the fecal waste treated in this manner, after addition of the enriched smectite clay and shortly before use of the treated waste as a fertilizer.
