Composting toilet

Abstract

A composting toilet comprising a housing having a seat disposed about an opening communicating with an aeration drum for receiving human waste matter. The drum is rotatably-mounted for rotation about a longitudinal axis oriented horizontally inside the housing. A removable receptacle adapted to receive decomposed solid waste matter from the aeration drum for periodic removal from the toilet is also provided. The aeration drum has a narrow front end for receiving and discharging waste, and a wide rear end extending radially outwardly from the front end. The rear end has liquid outlets in fluid communication with the housing and a gas outlet is disposed opposite the liquid outlets to cause an airflow through the composting solid waste and for venting any gases which enter the aeration drum or are formed through decomposition inside the drum. The configuration of the drum with the wide rear end is designed to collect gases in the rear end away from the seat area, provides increased capacity at the rear of the toilet so as to allow the seat which is at the front of the toilet to be lower and more conveniently accessible by a user, and defines a rear bottom surface which is always lower than at the front of the drum thereby improving the separation of liquid waste from solid waste.
