A system and method for vertically-oriented, modular, automated, emissions-controlled composting. In an 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.

The present disclosure relates to improved mobile composting systems, devices, and methods. In one example, a mobile composting system includes a garbage bin, a sorting table, a grinder, a conveyor belt, and a composting vessel. The garbage bin may include waste that includes compostable material. The sorting table may be adjacent to the garbage bin and may include a sorting surface configured to receive the waste and an inclined surface configured to receive the compostable material. The grinder may be positioned below the inclined surface for receiving the compostable material and may be configured to grind the compostable material and produce ground compostable material. The conveyor belt may have a first end positioned below the grinder to receive the ground compostable material. The composting vessel may be positioned below a second end of the conveyor belt.
