Abstract: A solid waste disposal system employs solid waste transport trailers adapted to be towed by a tractor. The trailers each comprise a closed body of a generally rectangular cross-section having a bottom, side and top walls, a forward end wall and a rear end wall. The top wall proximal to the forward end wall is provided with a loading neck through which solid waste can be loaded. The rear end wall is a door hinged at the rear edge of the top wall and is adapted to be closed during the loading operation and transport of the solid waste and opened for the unloading of the solid waste. A conveyor is located adjacent the bottom wall of the trailer and extends substantially over the entire length of the bottom wall. The conveyor is operable during loading and unloading to move the solid waste in a direction from the forward end wall toward the rear end wall. The trailer is supported by ground wheels with tires, the wheels being low pressure flotation tires to facilitate the use of the trailer on landfill sites.
