An apparatus for treating solid waste to produce a biomass product includes a cylindrical vessel includes a cylindrical vessel comprising a loading doorway and a discharge doorway at opposite ends of the cylindrical vessel. A cover in which first slits are formed in a lower portion of the same in a horizontal direction, is detachably engaged to a lower portion of the body and a comb plate which has one end connected with the vibrator and the other end having second slits formed therein in a horizontal direction, is vibrated such that the second slits move in upward and downward directions between the first slits. Users may selectively communicate with another user or broadcast simultaneously to all users in the group. The flow measurements are used to monitor carrier gas loss, anesthetic consumption, and anesthetic delivery time remaining and provide such information to the vaporizer operator. Both side walls of the shell have an internal groove extending parallel to and spaced from the bottom wall of the shell. The compositions comprise acid extracts or alcohol extracts from juglone-producing members of the Juglandaceae.
