A method of continuous composting is carried out in a train of composting trays in an elongate enclosed tunnel. Garbage is deposited into the composting tunnel via a blending trough in which blending augers blend the garbage. The trough then tilts to empty the garbage into an inlet in the top surface of the tunnel to fill an upstream one of the trays. A ram shunts the trays stepwise through the tunnel. The tracks may be U-channels, the webs of which are connected to tunnel sidewalls. The trays rest on one of the legs of the U and the other leg of the U extends over the edge of the tray to protect it from being fouled by garbage. During passage of the trays through the tunnel, the garbage may be mixed by mixers for loosening and aeration of the garbage. Such mixing may have directional components in both longitudinal and transverse directions of the tunnel. Water may be added immediately downstream of the mixing for the purpose of optimizing composting conditions. The water may be added into spray curtains from spaced apart spray bars above and immediately downstream of the mixers. The invention also includes a continuous composter having an blending trough for blending the garbage and for tilting so that the blended garbage falls into an upstream tray.
