  • 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: 7637054
    Abstract: Chemical combinations known to be used for odor control are provisioned for enhancing growth of a plant. The chemical combinations preferably include a stable, aqueous solution of a surfactant and a chemical source of oxygen. There are numerous ways by which one could learn that such combinations have utility in odor control. In preferred methods a manufacturer, distributor, retailer, farmer or other entity is informed of such through reading a journal article or other publication, or by a receiving a letter, fax, or email. The combinations can be used to reduce consumption of irrigation water and to increase a crop yield, each by at least 5-25%, as a consequence of applying the solution to a soil.

  • Patent number: 7497891
    Abstract: According to a method of producing a phosphate fertilizer, a first portion of the phosphate is produced in a pipe cross reactor, and a second portion of the phosphate is produced in a pre-neutralizer. Both the first and second portions of the phosphate are supplied to a granulator. Ammonia is added to the granulator to react with the first and second portions of the phosphate. To produce the first portion of the phosphate, a micronutrient is added to phosphoric acid to produce an enriched acid, and the enriched acid and ammonia are added to the pipe cross reactor where they are allowed to react to produce ammonium phosphate.
