Aqueous and solid ammonium sulfate fertilizers derived from an organic feedstock and a mineral sulfate compound. The aqueous fertilizers have at least 3.5% nitrogen and at least 4% sulfur, and the solid fertilizers have about 21% nitrogen and about 24% sulfur. Methods for producing the fertilizers include preparing an organic feedstock by causing organic waste to undergo anaerobic digestion, removing solids from the organic feedstock to produce an organic liquid effluent, performing a distillation process on the organic liquid effluent to strip and concentrate a vapor that contains ammonia, carbon dioxide, and water and cool the vapor to produce a condensed solution containing ammonium bicarbonate and/or ammonium carbonate, and contacting the condensed solution with the mineral sulfate compound to cause a reaction therebetween and produce an aqueous ammonium sulfate product. An evaporation process can be performed on the aqueous ammonium sulfate product to produce a dry, solid ammonium sulfate product.

A method of producing a fertiliser composition, the method comprising: (a) providing partially decomposed organic matter; (b) contacting the organic matter with: (i) an anaerobic digestate; (ii) a source of nitrate ion; (iii) a source of ammonia; and (c) contacting the mixture obtained in step (b) with a source of carbon dioxid. Also claimed is a fertiliser composition comprising partially decomposed organic matter admixed with an anaerobic digestate, a source of nitrate ion, a source of ammonia and carbon dioxide.

A digester system comprising a primary digester tank containing a primary feed material portion, a secondary digester tank containing a secondary feed material portion, a first conduit connected between the primary digester tank and the secondary digester tank to define a primary tank lower opening within the primary digester tank and a secondary digester tank lower opening within the secondary digester tank, and a flow control valve configured to allow or prevent flow of fluid through the first conduit. When the flow control valve is configured to allow flow of fluid through the first conduit, a portion of the primary feed material portion flows from the primary digester tank to the secondary digester tank to form the secondary feed material portion.

The present invention relates to organic nitrogen fertilizers and methods for producing organic nitrogen fertilizers, including retrieving high concentration organic ammonia from discarded organic material.

The present invention relates to methods and plants for the treatment of an organic waste material, wherein waste is subjected to anaerobic fermentation in a biogas digester; effluent is mechanically separated from the biogas digester into a concentrated fraction and a liquid fraction; the liquid fraction is heated to a high temperature below the boiling point of the liquid; the heated liquid is introduced to a flash column to partially remove volatile carbon dioxide, the pH of the liquid is elevated and ammonia is removed from the liquid.

An aerobic organic material processor includes a tank having an outer wall, a top, a bottom, a first end, a second end, and a horizontal axis. The tank is divided into compartments distributed along the horizontal axis of the tank between the first end of the tank and the second end of the tank. Each compartment is connected to other compartments by a fluid passageway toward the bottom of the tank. An agitator is provided for agitating the organic material within the tank. Fluid ports are positioned toward the top of the tank in communication with each of the compartments. Applying either a suction force or pressure to at least one of the fluid ports causes fluids to migrate from compartment to compartment via the fluid passageway, thereby aerating organic material within the tank.

A renewable energy microgeneration apparatus is disclosed that includes a mixing tank that mixes waste with a liquid, a buffer tank that receives and pre-warms the mixed waste, a pasteurization tank that pasteurizes on the pre-warmed mixed waste, a digestion tank that performs anaerobic digestion on the pasteurized waste, a de-watering device that separates liquid digestate and removes salt from the liquid, sensors that measure salinity and biogas quality, and a controller. The controller causes the transfer of digestate from the digestion tank to the pasteurization tank to the dewatering device, causes the de-watering device to separate the liquid and remove the salt from the liquid, monitors the salinity of the liquid and the quality of biogas using the sensors, and causes the mixing of the liquid with the waste and adjusts the feed rate of the waste to reduce the salinity of the waste and increase methane production.

A thermophilic enzymatic biosynthesis (TEBS) device (50) produces outputs of newly synthesized substances, stabilized matter and fully recovered organic material, wherein the preferred device is a dry closet employing multistage treatment of organic solid, liquid and gaseous wastes. Said contemplated device comprises a multiphase thermophilic environment chamber (MTEC) (1) having a mixing zone (4), a cultivation zone (12), a pasteurization zone (24) and a germination zone (7) which utilizes a multiphase germination (62). The device comprises a thermodynamic pathway (29) and a functional respiration (64) which is directed toward an ammine reaction chamber (ARC) (3), which includes an oxidation surface (47) having reactivity with ammonia, producing a metal ammine complex. The device further comprises a subterranean uptake chamber (SUC) (2) which includes a plant growth medium (44) where gases received from the ARC (3) disperse to an uptake root structure (46), thereby reducing carbon dioxide emissions.
