In one aspect, the disclosure relates to methods for biomass gasification to produce sustainable and renewable alternatives to fossil fuels including, but not limited to syngas having a high H.sub.2 content. The method can produce an H.sub.2/CO ratio close to 2:1, which is desirable for further chemical or transportation fuel synthesis. In another aspect, the methods disclosed herein have high yields and make use of agricultural and industrial waste (e.g., hardwood pellets and grain stovers) as starting materials. In a further aspect, the methods disclosed herein can produce useful byproducts including, but not limited to, carbon nanofibers (CNF). This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

A system and method for torrefying a combination of biomass and biochar colloidal dispersion is provided.

A mobile system for growing microorganisms and circulating nutrients for administering to plants. The system has minimal interior obstructions that can be easily removed for effective cleaning. The system comprises a mobile structure; a vessel supported by the structure for receiving water and nutrients; a pump supported by the structure; a generator supported by the structure for powering the pump; a vessel outlet from a bottom portion of the vessel to the pump; a first discharge line from the pump extending from the pump into the bottom portion of the vessel, wherein the contents of the vessel can be circulated by the pump from the vessel outlet back into the vessel through the first discharge line; a second discharge line from the pump for discharging contents of the vessel; and an aerator for injecting air into the first discharge line for aerating the contents of the vessel.

The disclosure relates to a composting device including a housing defining an interior with an access opening providing access to the interior, a composter bin located within the interior and in communication with the access opening, and a door mounted to the housing that includes a fascia.

The disclosure relates to a composting device including a housing defining an interior with an access opening providing access to the interior, a composter bin located within the interior and in communication with the access opening, and a funnel assembly integrated with the access opening.

A treated biochar comprising a porous carbonaceous particle that has been treated and mixed with a media containing a mineral solubilizing microorganism, whereby the porous carbonaceous particle after mixing has retained the mineral solubilizing microorganism.

A method is provided for removing tar from a gas by contacting a first gas containing tar with a second gas containing oxygen for time period sufficient to effect oxidation of at least a portion of the tar in the first gas, thus producing an oxidized product gas that contains less tar than the first gas. The method can also include heating a fluidized particulate material in a combustor, introducing the heated fluidized particulate material from the combustor and a biomass feedstock into a gasifier, such that heat from the heated fluidized particulate material causes the gasification of at least a portion of the biomass feedstock to form a tar-containing product gas, the first gas may contain at least a portion of the tar-containing gas, and the tar-containing gas may be extracted from the gasifier prior to contacting the first gas with the second gas.

The disclosure relates to a composting device including a housing defining an interior, and having a top wall defining an access opening providing access to the interior, a door moveable relative to the access opening between open/closed positions to selectively open/close the access opening, a trim bezel with a trim bezel opening, and a bin located within the interior and having a fill opening in communication with the trim bezel opening.

A method for producing a poultry litter-based fertilizer by a) supplying poultry litter to a rotating rotary drum, b) adding acid or a source of acid to the rotating rotary drum, wherein acid reacts with the poultry litter to form an acidified mixture, c) adding ammonia or a source of ammonia to the rotating rotary drum, d) drying and cooling the ammoniated product by evaporation of water to form a dried, cooled product in a free-flowing semi-solid or solid form, repeating the steps b) through d) until a desired nitrogen content is reached in the poultry litter-based fertilizer.

An system for processing biomass comprising a stator, a rotor having an axis of rotation, the rotor being disposed inside the stator and configured to rotate about the axis of rotation therein, a processing chamber defined between the rotor and the stator, an inlet in fluid communication with the processing chamber which is designed to introduce unprocessed biomass into the processing chamber, an outlet in fluid communication with the processing chamber which is designed to carry out processed biomass from the processing chamber and a pump operationally associated with the inlet and the outlet, wherein the pump is configured to pump the unprocessed biomass through the processing chamber.
