A dewatering machine includes a screen, a screw and at least one moisture content control wing. The screen has a hollow inside, has an inlet portion through which livestock manure is inputted at a first side and an outlet portion through which dehydrated livestock manure is outputted at a second side, and has a plurality of moisture exhaust holes penetrating from an inside of the screen to an outside of the screen. The screw includes a rotation axis and a main wing formed into a spiral shape along a longitudinal direction of the rotation axis. At least one moisture content control wing is disposed between the main wings adjacent to the outlet portion, and is formed into a spiral shape along the longitudinal direction of the rotation axis.

The subject invention provides improved methods for processing livestock waste, namely, for solid-liquid separation of manure, utilizing microbe-based products. In preferred embodiments, microorganisms and/or microbial surfactants are utilized to improve solid-liquid separation of livestock manure in ways that enhance the value of manure-based fertilizers to farmers and reduces greenhouse gas and other polluting emissions resulting from manure storage.

The invention relates to the use of an amendment composition comprising an extract of Cynara leaves for stimulating the nitrification of a soil, a process for stimulating the nitrification of a soil with an amendment composition comprising an extract of Cynara leaves and an amendment composition comprising an extract of Cynara leaves and one or more compound(s) selected from (i) a basic calcium amendment, (ii) a yeast extract, and (iii) an extract of a legume of the family Fabaceae.

A plant growth enhancer including a source of carbon dioxide, a source of carbohydrate, and source of acid in an amount to provide increased retention of carbon dioxide in the soil. A method of enhancing the growth of plants by applying the plant growth enhancer to the soil containing the plant, the acid increasing retention of the carbon dioxide in the soil, and the plant exhibiting enhanced growth from the combination of the carbon dioxide and carbohydrate.

A bulk animal bedding material is presented comprising shredded and fiberized natural lignocellulosic material vigorously blended with a solvent and small grain particles (SGPs) to form twisted, curled, clumped, and rolled fibers with the SGPs integrated within and/or encasing said fibers.

A method of pH regulating biomass residues includes the steps of: providing biomass residue comprising solid and liquid parts; exposing the biomass to one or more separation steps, wherein said biomass is separated into one or more solid fractions having a reduced content of water, and one or more fluid fractions; and adding a pH regulator to the biomass residue, and/or the one or more solid fractions, and/or the one or more fluid fractions, wherein the pH regulator comprises a juice derived from agricultural biomass and/or fish manure.

A biosolids treatment system that treats human biosolids to produce thermal energy for self-consumption for the production of beneficial use products including low carbon ash, high carbon activated biochar, and Class A biosolids. The system includes a variable feed conveyor that conveys a biosolid feed into a dryer; a dryer that dries the biosolid feed to a predetermined moisture content to create one of a beneficial use products, where the predetermined moisture content is controlled by varying the speed of variable feed conveyors and a variable feed mixer; and a gasifier that converts the biosolid feed into two of the beneficial use products.

A process of treating sewage sludge and the formation of a granular product thereof, wherein said process comprises utilizing a urea-formaldehyde resin to treat a sludge product from thermal hydrolysis processes (THPs) to create an end product for agricultural and other uses. The process utilizes a high intensity mixing and chopping reactor, which combines the sludge with a resin and utilizes sulfuric or other mineral acid to polymerize the resin. The resultant product is subsequently dried and sized through a screening process. The process results in an end product that is a granular fertilizer that is substantially dehydrated and a substantial portion of the nutrients having low solubility and slow release rates. This reduces or eliminates the loss of plant nutrients to water runoff effects. The novel process results in a product that is a low-odor, enhanced fertilizer useful for the processing and utilization of sewage sludge for agricultural and other purposes.
