Patent number: 8992654Abstract: The invention is directed to manufacture of fertilizer having commercial levels of nitrogen supplemented with organic substances. The process treats organic matter with acid causing hydrolysis of organic polymers after which the mix is injected with nitrogen. The resultant sterilized and liquefied organic matter is disbursed over recycled material for the production of granules. Because the process allows for the controlled addition of acids and ammonia, desired levels of components can be achieved. The process is scalable, odor controlled and safe thereby allowing for the location of biosolid processing facilities in most any location. Further, the fertilizer of the invention provides a dual nitrogen-release profile when applied to crops. After application to soil, fertilizer of the invention releases an immediate bolus of nitrogen, similar to traditional ammonium sulfate, followed by continued slow release of nitrogen typically over a season.Type: GrantFiled: March 28, 2012Date of Patent: March 31, 2015Assignee: VitAg CorporationInventors: Gary L.

Patent number: 7507577Abstract: The invention discloses a treatment apparatus for the excrement and a bio-toilet using the treatment apparatus. The treatment apparatus includes a tank, a reactor basin in the tank for containing the raw material and the excrement and having at least two parallel, concave parts having curved profile in the bottom part of the tank, a temperature control means for maintaining the temperature of the basin at a predetermined range; and at least two mixing devices which match with the at least two concave parts, each of them can rotate around a rotation shaft, the helical blade stirrer secured to the rotation shaft by a plurality of spokes. The bio-toilet is waterless, and thus a large quantity of water can be saved and the pollution of the environment due to the drainage of sewage can be avoided. Furthermore, treated by the treatment apparatus of the present invention, the microorganisms and the organic materials are combined and converted into stable loosen soil and the organic components.Type: GrantFiled: January 13, 2004Date of Patent: March 24, 2009Inventor: Andy Ming Fen Tung

Patent number: 7169204Abstract: An improved process for enhancing the plant nutrient value of relatively low analysis organic waste material (e.g., sewage sludge) involves treating the waste material with an acid and base in a pipe-cross reactor. The process more particularly involves mixing the waste material with water to form a slurry (or initially taking the waste material as a slurry); pumping the slurry to a pipe-cross reactor for reaction with a base, acid, and water to form a melt; spraying the melt onto a recycling bed of fines in a granulator, and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles to form an enhanced plant nutrient value composition (e.g., a fertilizer or soil conditioner having a greater “NPK” value than the original relatively low analysis organic waste material).Type: GrantFiled: July 6, 2004Date of Patent: January 30, 2007Assignee: Environmental Technologies Capital Partners LLCInventors: Gary D. Greer, Gary L. Dahms

Patent number: 7128880Abstract: The invention is directed to a process for enhancing the plant nutrient value of relatively low analysis organic waste material (e.g. sewage sludge) involves treating the waste material with an acid and base in a pipe-cross reactor or tubular to form a melt; spraying the melt onto a recycling bed of fines in a granulator and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles to form an enhanced plant nutrient value composition (e.g. a fertilizer or soil conditioner having a greater NPK value than the original relatively low analysis organic waste material). The process further includes drawing off the fumes from the granulator, passing them through a dryer with the granulated particles, and subsequently oxidizing the fumes to eliminate volatile organic compounds and/or gaseous hydrocarbon pollutants be converting such into carbon dioxide and water vapor.Type: GrantFiled: December 19, 2002Date of Patent: October 31, 2006Assignee: Environmental Technologies Capital Partners LLCInventors: Gary L.

Patent number: 7029512Abstract: Disclosed is a method for enhancing the concentration of vermicompost comprising the steps of liquefying and agitating a vermicompost feedstock; separating large bodies from the liquefied feedstock and further separating the remaining portion into first and second sub-portions; centrifugally separating the first sub-portion into light and heavy portions; returning the light portion to the liquefying and agitating step; separating biological vermicompost components from the second sub-portion and heavy portion using a biological filter; returning the liquid to the liquefying and agitating step; innoculating the biological vermicompost components with food and/or supplements; further enhancing the concentration of the biological vermicompost components by allowing the biological vermicompost components an effective amount of time to multiply and dry; and packaging the biological vermicompost components.Type: GrantFiled: October 29, 2003Date of Patent: April 18, 2006Inventor: Wesley M.

Patent number: 6966941Abstract: An apparatus and method for treating organic waste sludge such as sewage sludge is disclosed wherein the sludge is first dewatered, moved to a day hopper for storage, and then successively passed through first and second reactors. As the sludge is passed through the first reactor, in a continuous fashion, the sludge and acid are thoroughly mixed and has the pH thereof substantially lowered due to the addition of acid in the first reactor. The sludge is then moved through the second reactor where the sludge is subjected to a base material to substantially raise the pH thereof. The treated sludge is then pumped from the second reactor to a pugmill and then to a dryer which dries the material. The dried material is then suitable for use as a fertilizer.Type: GrantFiled: November 11, 2002Date of Patent: November 22, 2005Assignee: BER Systems, Inc.Inventors: Marius Grobler, John A. Bewsey, Oliver O. Hart

Patent number: 6863826Abstract: Animal waste such as fecal material from swine, chicken, turkey, and cattle is converted into useful forms such as fertilizer, other types of soil builders, and even nutrient feed additives. Devices, systems, and methods are provided that allow economical conversion and in many instances, alleviate the production and release of undesirable gases such as sulfide and ammonia. In one embodiment, undesirable anaerobic and facultative anaerobic bacteria are killed at a greater rate than desirable soil compatible aerobic bacteria. The use of low temperature killing diminishes off gassing commonly associated with other techniques, and the use of gas trapping additives such as zeolites provides enhanced soil building qualities such as slow release of nitrogen and slow release of moisture to soil. The methods allow convenient adjustment of composition, allowing conversion of waste into tailored designer fertilizer suited for particular soils.Type: GrantFiled: November 25, 2003Date of Patent: March 8, 2005Inventor: Richard G.
