摘要:
Integrated waste treatment and fertilizer and feed supplement production methods to be implemented at organic waste source sites, at remote treatment sites, or partially at the organic waste source site and at a remote location, whether in small or large scale operations. The methods are suitable for retrofitting existing organic waste sources and for treating the organic waste generated by a single source or by a plurality of sources. These methods provide: reduction or elimination of emissions of acrid and greenhouse gases; effluents that meet discharge standards and that can be used in wetland and irrigation projects; organic based, granular, slow release NPK fertilizer of standard composition and size that can be supplemented with micronutrients and soil amendment materials and whose composition can be adjusted to meet demands and needs of specific markets; methane-rich biogas recovery for its subsequent use for heating, for power generation or for catalytic and synthetic processes, and feed supplement including feed supplement for cattle. The methods comprise steps for thoroughly separating suspended and dissolved materials, preventing gas emissions and capturing gases, and minimizing waste disposal. Fertilizer base may be produced by mixing waste with at least one of a phosphate precipitating agent, a base, a flocculant, and optionally with an ammonia retaining agent and a densifier, subsequently separating and drying the precipitate. Pathogen-free, odor-free and dust-free fertilizer may be obtained by temperature controlled incineration or combustion.
摘要:
A method of sustaining plant growth in toxic substrates polluted with heavy metal elements, characterized in that it comprises amendment and remediation of the toxic substrates with an organo-zeolitic mixture. Vegetation, such as hyperaccumulator plants or native plants and grasses for in situ remediation, will now grow. The method can also be used as a fertilizer and for beneficiation of normal, uncontaminated soils.
摘要:
A method of disinfecting and stabilizing organic wastes where organic waste is intimately mixed with one or more mineral by-products to produce a mixture having a pH of less than about 9. The mixture is heated and dried to produce a stable, granular bio-mineral product that may be used for example, as a fertilizer, soil amendment or as a soil substitute. Also provided are stable, granular bio-mineral products formed by the methods of the present invention and fertilizers, soil amendments, and soil substitutes that include these stable, granular bio-mineral products. Further provided are systems for disinfecting and stabilizing organic waste, and systems for making a stable, granular bio-mineral product.
摘要:
A vessel for growing a plant, comprising: a base material 11 in the from of a vessel which is capable of accommodating therein at least a part of a plant; and a hydrogel-forming polymer 12 having a crosslinked structure disposed in the inside of the vessel-form base material 11. When such a vessel is used, the transferring operation for the plant can be automated, and the transferring damage to the plant can be reduced at the time of the transferring operation for the plant.

摘要:
The fertilizer of the invention is a fertilizer containing a sparingly water-soluble phosphatic fertilizer and a urea/aliphatic aldehyde condensation product. The process for controlling inoganizing speed of urea/aliphatic aldehyde condensation product of the invention comprises adding to the urea/aliphatic aldehyde condensation product a sparingly water-soluble phosphatic fertilizer having special elution characteristics. The fertilizer of the invention and the process for controlling inoganizing speed of urea/aliphatic aldehyde condensation product of the invention make it possible to control the inorganizing speed of the condensation product without changing the particle size or form, that is, to control development of the efficacy of the condensation product used as a fertilizer. The fertilizers of the invention or the urea/aliphatic aldehyde condensation products whose inorganizing speeds are controlled according to the process for controlling the inorganizing speed of the invention can provide nitrogen components to plant in accordance with the periods of culture of desired crops and a pattern of absorbing nutrition. This is effective in saving of the number of additional fertilization or nitrogen components left in soil after the period of culture.
摘要:
A hydratable oxidized keratin composition comprising one or more metal ion species capable of absorbing water to form a hydrogel. The keratin material is useful as a soil amendment providing organic and inorganic nutrients. The keratin material is also useful as a nutrient source in the bioremediation of toxic contaminants soils and liquids.
摘要:
Exhaust gas 2 from a coal power generator 4 may be used to provide a commercial soil additive. The exhaust gas 2 is fed to a growing cell 14 containing bio-mass material. After the bio-mass material matures, the bio-mass material is harvested to produce the commercial soil additive, which is preferably treated to produce mulch 18 and compost 20.
摘要:
The invention provides an improved, cost-effective means of transforming sludge or ther waste from vertebrates into fertilizer comprising the steps of 1) mixing a composition containing calcium oxide (CaO) and magnesium oxide (MgO) with sludge or other waste products from vertebrates, 2) allowing the mixture to reach a temperature of about 70null C., then 3) allowing the mixture to remain at a minimum temperature of about 70null C. for a minimum 30 minutes. At the end of this time, most of the material is sufficiently dewatered and can then be bagged to be sold as an organic fertilizer.
摘要:
An economical and effective process is provided to remove water from organic waste material, such as manure, and to further facilitate various different fertilizer applications or uses for the product material produced. The process employ a pulverizing air drier that utilizes a high impact vortex or cyclone of forced air. Additionally, the process sanitizes and the raw organic material and nullmicronizesnull the organic material as well as or better than conventional thermal drying, which must be coupled with supplemental grinding or pulverizing techniques. To help preserve the nutritive, water soluble components of the raw organic material, the material is acidified prior to drying. To further minimize the loss of nutrients in the product fertilizer, water soluble components removed by the drying process can be recovered recycled back into the product. Additional nutritive component can be added to the material to produce a desired fertilizer formulation. The dried product also exhibits a substantial reduction in bacteria and pathogens, as compared to conventionally processed manure based fertilizers. Additionally, the product is substantially free of weed seeds and insects, all typically present in the raw organic manure material.
