This invention discloses systems and methods for conversion of manure to novel fertilizer and / or soil builder products useful as input for organic farming operations. The equipment systems comprise a gas turbine generator unit (preferred heat source), a dryer vessel and a processing unit, wherein the connection between the gas turbine and the dryer vessel directs substantially all the gas turbine exhaust into the dryer vessel and substantially precludes the introduction of air into the dryer vessel. The dryer vessel receives the manure for contact with the turbine exhaust gases to convert the manure to a dry material, which is passed to the processing unit where it is formed into granules, pellets or other desired form for the final dry fertilizer product. The method comprises drying, heating and converting the manure to form novel self binding fertilizer and soil builder type products for organic farming and other uses.

Apparatuses and methods for anaerobic digestion of high-solids waste are provided. The methods may include and the apparatuses may be used for moving the solid waste in a corkscrew-like fashion through a closed container. The method may further include moving the high-solids waste into contact with a heating device to facilitate the corkscrew-like movement. Other methods and apparatuses may use at least one of a partition and a conduit from which liquid or gas is discharged.

Improved systems, methods, apparatus and compositions for generating, extracting and distributing the renewable heat energy produced by microbial decomposition of organic biomass within a contained and controlled environment. This heat energy is preferably transferred and distributed, preferably by the use of heat pipes, to the interior of a greenhouse or other structure to be heated, either directly or via heat exchange apparatus such as hot water heating systems. In one embodiment heat transfer and distribution mechanism customized to the application requirements of a greenhouse heating batch-type process is disclosed, along with a recipe for a readily available biomass material composition. Additional continuous and batch process embodiments of biomass heating systems are also disclosed that extract heat energy from decomposing biomass for heating uses. In some embodiments gaseous products generated in a biological decomposition process, primarily CO2, are utilized to enhance plant growth in the greenhouse environment.

The invention provides a solid high-temperature aerobic fermentation reaction system and method. The system comprises a solid high-temperature aerobic fermentation system, a furnace system, an odor and flue gas treatment system, a detection system and a control system; the solid high-temperature aerobic fermentation system comprises 1-X solid high-temperature aerobic fermentation reactors, and each solid high-temperature aerobic fermentation reactor comprises an oblique horizontally drum, a feed side, a closed labyrinth sealing device arranged on a discharge side, a power supporting wheel set, a stirring anti-sticking device and an integrated base, wherein the horizontal drum is sleeved with a water sleeve, the stirring anti-sticking device is located in the horizontal drum, and the horizontal drum is arranged on the power supporting wheel set; the furnace system comprises a hot water furnace, a circulating water pump, a three-way electric adjusting valve and an electromagnetic valve, and effluent of the furnace system is connected and communicated with clamping sleeves of the solid high-temperature aerobic fermentation reactors; the odor and flue gas treatment system comprises an odor heat exchange condenser, a flue gas heat exchange condenser, a biological deodorizing filter tower, an induced draft fan and an electromagenetic valve; the detection control system is set in the mode that all system sensors output detection signals to be connected with a controller, and the controller controls all the systems to work coordinately. The system conducts reductive, harmless and resourceful treatment on pollutants, is small in occupied area, high in fermentation efficiency and good in environment-friendly effect and is not influenced by environmental factors and a low-temperature condition.

Systems and methods for automated, rapid composting are disclosed. An air-tight housing prevents odors from leaking out. The housing is thermally insulated to enable the compost to achieve sufficient temperatures for rapid composting. A chambered system, generally including an optional hopper, a reactor, and a cure tray, physically shields odorous material from the external environment. A mixing wand mechanically mixes and / or breaks up the compost material and enhances air flow therethrough. A drip tray segregates liquid byproducts from the solid compost material. An air pump draws in air, while a carbon filter may absorb odors before returning the air to the external environment. A motor provides mixing, and facilitates opening and closing of the two trap doors separating the chambers. An electronic controller automates the composting process while allowing certain settings to be adjusted.

A method and apparatus for operating a composter device includes a compost container, a condensate reservoir, a first fluid pathway fluidly coupling the composting chamber and the condensate reservoir, and a fan moving air from the composting chamber to the condensate reservoir along the first fluid pathway to define a first airflow.
