A toilet bowl (18) has a discharge opening (26) for flowing waste material into a gas-tight hopper (30). A waste valve (34) is disposed between the discharge opening and the hopper for controlling the flow of waste material into the hopper. A first air valve (104) selectively allows air to flow into the hopper for pressurizing the hopper and communicating the waste material from the hopper to the inlet (42) of a grinder (46). The outlet (50) of the grinder is coupled to a one-inch waste conduit (58) which leads to a waste tank (64) which may be disposed in any convenient location. A second air valve (108) selectively allows air to flow into the waste conduit for pressurizing the waste conduit and forcing the waste at high velocity to the waste tank.
