I highly recommend the Humanure Handbook method to process with no runoff into the ground. Burying unprocessed waste, especially as fertilizer near food, places pathogens in proximity with food and Joe's referenced research includes evidence of pathogens being absorbed into food crops where there's no washing it off. You definitely shouldn't go that route, instead use thermophilic composting which works really well when you include feces and urine in the
compost, don't separate it. Hot compost goes through a lot of moisture, and if you cover it properly as Joe explains, there is no smell indoors or outdoors.
