A system and method for vertically-oriented, modular, automated, emissions-controlled composting. In a preferred embodiment, the system and method involve construction of a vertically-oriented set of composting modules comprising a receiving and offloading level, one or more composting bay levels, a feedstock staging level, a biofilter level, a vertical conveyor for uploading feedstock to the feedstock staging level, a freight and personnel elevator, and a leachate tank. This composting system and method reduces the land area required for composting, increases the capture of emissions from composting, and reduces the labor-intensive and heavy-equipment-intensive nature of current methods.

An aerobic organic material processor includes a tank having an outer wall, a top, a bottom, a first end, a second end, and a horizontal axis. The tank is divided into compartments distributed along the horizontal axis of the tank between the first end of the tank and the second end of the tank. Each compartment is connected to other compartments by a fluid passageway toward the bottom of the tank. An agitator is provided for agitating the organic material within the tank. Fluid ports are positioned toward the top of the tank in communication with each of the compartments. Applying either a suction force or pressure to at least one of the fluid ports causes fluids to migrate from compartment to compartment via the fluid passageway, thereby aerating organic material within the tank.

The invention relates to an installation for toilets (2) installed in a building and comprising, for each of the toilets (2), firstly a separator device (20) for separating liquid effluent and solid waste, and secondly a transfer device (20) for moving solid waste into a descent tube (21), the descent tube (21) having a plurality of through openings (22) communicating with a plurality of transfer devices belonging to toilets installed on storeys of the building, and enabling solid waste to be taken by gravity to a treatment device positioned at the bottom of the building.
