  • Patent number: 10787397
    Abstract: The present invention provides highly water soluble products derived from humin, as well as methods of obtaining such products. Humin is first blended with water and a nitrogen source, such as urea, under intense agitation and heating, in order to disperse the nitrogen source. Thereupon, the blend is incubated for an extended period to create nitrogen-reacted humin having the desired solubility properties. The products may be used as aqueous dispersions, or dried in the form of particulates.

  • Publication number: 20140311201
    Abstract: A flow wood processing extracting lignin from woody plant material and converting delignified cellulosic residue to crude bio-oils, that removes toxic preservative chemicals from waste timber, and provides conversion to useful or nontoxic forms. Wood is chipped and fed into a lignin extractor using ethanol at high temperatures to dissolve the lignin with counter current material contactors, heat exchangers, and a computer control system. Most of preservative chemicals likely precipitate out at this stage as a heavy sludge that can be removed. Ethanol containing dissolved lignin is removed from the lignin extractor, the dissolved lignin recovered, the ethanol recycled into the lignin extractor, and residual heat returned to the process. Delignified cellulosic pulp is removed from the lignin extractor and subjected to a milling to convert into a smooth sludge for entry to a bio-convertor by a super critical water process. The residue is prepared as a high phosphate fertilizer.

  • Patent number: 8491693
    Abstract: This invention is directed to systems, devices and methods to beneficiate heat-dried biosolids or sludge pellets or granules as presently manufactured by municipalities or companies from a) dewatered municipal wastewater biosolids or sludges within the municipal wastewater treatment plant heat-dried biosolids production facility or from b) finished dry heat dried biosolids pellets or granules in a separate manufacturing facility from the municipal wastewater treatment plant to produce a fertilizer containing sufficient organic and inorganic plant nutrients to be valuable and saleable into the commercial agricultural industry. The present invention describes beneficiation methods to increase the plant nutrient content of the fertilizer and also to reduce the odors associated with traditionally-produced heat dried biosolids.

  • Publication number: 20130174625
    Abstract: Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste.

  • Patent number: 8475558
    Abstract: Provided is a freely flowing particulate fertilizer essentially consisting of potassium phosphate of the formula K3H3(PO4)2 and of less than 8 wt % water. The stable and not caking fertilizer is characterized by an XRD signal corresponding to 2-theta of about 70°. An economic process for making the fertilizer is also provided consisting in reacting KOH and monopotassium phosphate (KH2PO4) in water, heating the mixture under vacuum and cooling it down, thereby obtaining the particulate fertilizer.

  • Patent number: 8470065
    Abstract: The invention describes a new method for the production of high nitrogen organically-augmented inorganic fertilizer that incorporates municipal biosolids or organic sludges that can compete with traditional fertilizers such as ammonium phosphate, ammonium sulfate and urea on the commodity fertilizer marketplace. The method creates a thixotropic paste-like material from the biosolids or organic sludge that is blended with hot or molten ammonium salts, especially a mixture of ammonium phosphate and ammonium sulfate. The invention can be an add-on to commercial production of ammonium salts or it can stand alone by manufacturing ammonium salts prior to their introduction to the conditioned biosolids. The invention is oriented to be tailored to production facilities for individual municipal waste treatment plants in order to keep manufacturing plants small with a minimization of logistics and liability.

  • Patent number: 8419820
    Abstract: Improved, solid water-soluble fertilizer (WSF) compositions are presented which comprise at least one acid (optionally nutritive) and at least one basic fertilizer component. In one or more embodiments of the present invention, the WSF compositions demonstrate improved solubility of one or more nutrients or additives in solution, do not require additional dissolution aids or anti-caking agents, demonstrate fast dissolution times, produce precipitate free solutions, are readily compounded without intermediate wetting or drying steps, do not generate gas, and demonstrate improved stability under typical usage conditions. Finally, the WSF compositions may be used in improved processes for the creation of stock solutions, optionally with cold water, and/or delivery of nutrients to plants.

  • Patent number: 8361186
    Abstract: The invention provides for methods, devices, and systems for pyrolyzing biomass. A pyrolysis unit can be used for the pyrolysis of biomass to form gas, liquid, and solid products. The biomass materials can be selected such that an enhanced biochar is formed after pyrolysis. The biomass can be pyrolyzed under specified conditions such that a selected biochar core is formed. The pyrolysis process can form a stable biochar core that is inert and/or resistant to degradation. The biochar or biochar core can be functionalized to form a functionalized biochar or functionalized biochar core. Functionalization can include post-pyrolysis treatments such as supplementation with microbes or physical transformations including annealing and/or activation.
