  • Patent number: 10125055
    Abstract: A process is disclosed for creating biologically active soil or horticulture media for growing plants, wherein a fibrous carbon source such as coconut coir in a predetermined particulate form is mixed with fertilizers and other biological nutrients, inoculated with a biologically active substance such as worm castings and then aged or cured in an oxygen rich aerobic process. After which additional nutrients can be added to tailor the aged media for a specific sue. Various apparatus with which to conduct the aging process are also described. In a variation of the process used soil or horticulture media is recharged by first composting at a high temperature to remove harmful and unwanted items, its contents are evaluated, nutrients are added, and it is then aged in an aerobic process.

  • Publication number: 20150107319
    Abstract: A method for sterilization of pathogenic waste includes steps of introducing animal tissues, carcasses or parts, pathogenic waste, or by-products of slaughter or processing into an unpressurized vessel, adding NaOH and KOH in a ratio of about 2.2 to 2.3:1, adding water sufficient to create a 1.5 to 1.6 Molar solution, such that the tissue to water ratio is about 1:1.5, heating the vessel indirectly to near but below the boiling point of the solution, holding the temperature for about 16-20 hours, while continuously agitating the contents of the vessel, displacing the solution volume in the reaction vessel about every 2-3 minutes. Optimally, the tissue is introduced into the vessel first, then dry NaOH and KOH, and finally water. The end product is a homogenous, aqueous solution that is sterile, pathogen-free and suitable for land application or mixing directly into manure retention vessels, prior to land application of the mixture.

  • Patent number: 8092569
    Abstract: This invention includes uses and methods of preparing phosphites and/or hyposphosphites (and their polymeric forms and/or their salts) and phosphite-based agrochemicals (fertilizers and biocides) from phosphate or other naturally occurring or synthetic phosphorus sources using anaerobic microbial fermentation. The fermentation process produces both a liquid and solid phase phosphite/hypophosphite salts which can be used as an agrochemical product.

  • Patent number: 8066793
    Abstract: Dry fertilizers of biologically degraded crushed minerals such as limestone, rock, or rock phosphate together with micro-organisms, including one or more selected supplementary trace elements, are described. Minerals, some sawdust, an inoculum, and nutrients or other protein material, including bound selected micro-elements or trace elements are stored under aerobic conditions for some weeks during thermophilic biological degradation. The resolution fertilizer releases the macro-elements and micro-elements over a long period of time. The microelements are include within a biomass of micro-organism (5-6% carbon in the resulting fertilizer) and are more effective in remedying plan or animal deficiencies than if administered as inorganic salts. Furthermore this fertilizer avoids leaching of mineral including phosphate (phosphorus) and microelements into groundwater, streams, rivers or lakes.

  • Patent number: 8017013
    Abstract: Apparatus, methods and systems for processing waste are provided. For example, a system for processing waste, wherein the waste comprises hard particulates embedded therein, can be provided. The system can comprise a waste disrupter, wherein the waste disrupter disrupts the waste and releases at least one of the embedded hard particulates from the disrupted waste; a segregator, wherein the segregator segregates at least one of the released hard particulates from the waste; and a dilution unit, wherein the dilution unit dilutes the waste. In some embodiments, the system can include a waste loader that provides waste continuously to the waste disrupter, which is configured to disrupt at least a portion of the continuously provided waste.

  • Patent number: 7951296
    Abstract: One embodiment of an apparatus and method for treating agricultural animal wastewater that costs less to build, is easy to operate, and requires little energy input. The method employs natural systems for wastewater treatment; an initial anaerobic digestion treatment followed by batch floating aquatic plant treatment. The batch floating aquatic plant treatment of effluent and subsequent batch discharge provides increased control of the treatment process. Opportunistic collection and use of biogas and floating aquatic biomass results in additional benefits. The apparatus reduces the cost and land area required for the system by subdividing a lagoon into an anaerobic digestion treatment zone below the apparatus and a floating aquatic plant treatment zone above the apparatus. In addition, the apparatus is disposed in the lagoon in such a way that it facilitates the collection of biogas evolving from anaerobic digestion treatment beneath the apparatus by diverting it to areas to be collected.

  • Patent number: 7892310
    Abstract: A method of treating bio waste including the steps of (1) fermenting substantially raw biowaste in a pathogen reduction stage under anaerobic conditions for a predetermined period at a temperature in the mesophillic temperature range and (2) subsequently separating the solid and liquid phases to produce a fermented cake and fermented liquor. The fermented cake has at least 15% solids on dry basis and contains over 500 mg/L ammonia, over 1,000 mg/L total Volatile Fatty Acids (tVFA) and Escherichia coli less than 100,000 cfu per g dry solids. The fermented liquor contains over 10,000 mg/L COD, over 500 mg/L ammonia, over 1,000 mg/L tVFA and less than 5,000 mg/L of suspended solids.
