Hi-value biomass nutrients in livestock farming operations can be reclaimed as composted soils with added supplements or digested for methane biogas with the spent solids being composted mixed with biochar and applied for soil remediation and conditioning.

The Marvel II Composting System provides flexibility regarding product chemistry & quality with our technology. Marvel has the capability to transfer biomass from bin to adjacent bin in real time.

A large scale existing biomass composting facility at Michigan State University has provided prior art herein, and has been re-designed to produce an upgraded and advanced agricultural composting system that is can alter the biomass chemistry with biochar and other ingredients.

Global Earth Products has been the designer and builder of the initial existing pilot plant at MSU whereas Sono-Dyne Scientific has re-engineered and streamlined the process with the machinery to integrate biochar into said process.

The MSU facility has an existing prototype development version which is still in service after some 20 years, from which attributes have been learned in how to produce our Marvel II “Super-Soil” with the addition of biochar to the compost.

The existing machinery at MSU is hydraulically powered throughout, whereas Marvel II is totally electric AC motor powered without any hydraulic components whatsoever.

The ability to agitate and turn over the biomass in the bins periodically through various stages of composting is of great benefit to the quality of product. Aeration is integrated into the flooring of the bins to provide adequate microbial aspiration.

The compost turner in the trolley has articulated cross feed conveyors that can transfer in progress compost biomass from any bin to an adjacent bin while adding biochar or nutrients from feeder chutes above the transfer belts. Other additives or feed stock can also be added at any stage to the composting biomass in progress.

One of the two cross transfer conveyors is shown in the deployed position where compost is deposited onto its conveyor belt by the apron conveyor that is scooping the biomass from the bottom of the bin itself. The cross feed transfer is functional with both forward and reverse directions.

In doing so, the biochar discharge chute above the transfer conveyor deposits a measured amount of biochar onto the compost as it’s ejected into the next adjacent bin.

The biochar dosing process is accurately metered with simple technology and improves the quality with value added to the finished compost.
