This little 12 Volt gadget is a used food processor. Not a food processor that's used, but a processor for used food: aka that stuff in the black & gray holding tanks on a camper! It will pulverize everything in the tank in a matter of seconds... and then I simply send the output straight into our septic tank (depending on how often you do this, you'll definitely want to add a product like Microbe Lift to the septic tank at least twice a year, if not more).
