A toilet waste holding apparatus for a vehicle comprising: a tank comprising a top and a bottom, the top having a vent opening therethrough, a horizontal partition dividing the tank into upper and lower tanks, said partition and tank top having aligned openings therethrough, said lower tank being arranged to receive a store of liquid up to a normal liquid level, a removable insert defining a waste receiving passage and extending above the tank top and through said aligned openings into said lower tank above the normal liquid level, said insert fitting loosely into said partition and tank top openings so as to permit air flow around the outside of said insert, and means for positioning the insert with respect to the tank top, means for allowing an overflow of liquid within the tank to flow onto the tank top, a vent pipe connected to the tank so as to pass through the vent opening in the top, said opening being sufficiently large to permit air and gases to flow around the vent pipe, the vent pipe having first and second ends, the first end being disposed above said tank top for carrying away air and gases released from any waste material in the tank and passing through said opening in the top between tHe top and the pipe, the second end extending below said tank bottom and having an angle cut in the end. means, independent of vehicle motion, for blowing a stream of air past said second end so as to suck air and gases from within said vent pipe, and a vent pipe cap mounted over said first end and connected to the tank top around the vent opening such that suction in the vent pipe will pull air and gases flowing through the top opening around the pipe into the pipe while allowing any overflow of liquid to run across the tank top without entering the vent pipe.
