Claim 11:
12. The waterless toilet of claim 1, wherein each said end plate has two opposing upper roller axle channels and two opposing lower roller axle channels recessed into the given said end plate, each said roller axle channel extending from a channel open end at a plate side edge inwardly and upwardly to a downward bend in the channel forming a channel corner and a channel end segment around the channel corner, terminating in a channel closed end, and said hex head end of a corresponding roller axle is sized to fit closely into a corresponding axle channel open end and is slidable along the axle channel, around the channel corner and into the channel end segment, which securely but removably retains the axle crown, and finally abuts the channel closed end, and the sides of the axle channel are spaced relative to the width of flat faces of the hex head end to engage and constrain the hex head end and thus the roller axle against rotation relative to said first and second end plates, wherein the channel closed ends for each roller set are farther apart than the corresponding channel open ends, such that when said hex head ends of said axles of the upper and lower rollers of a given roller are inserted into the corresponding said upper and lower channels, said axles progressively move apart from each other as said hex head ends are advanced along their respective channels and around the channel corners into the respective channel end segments, and such that their progressive separation gradually tightens the given said feed belt around its respective roller set until the feed belt is fully taut.
