The present invention concerns a method for recovering phosphorus by thermochemical reaction of a phosphorus-containing material such as an alternative fuel, for example, in the presence of calcium-containing particles in a moving bed reactor and subsequent separation of fines enriched with phosphorus from the moving bed reactor. Furthermore, the present invention concerns the use of a recyclable material obtained by the method as a fertilizer or fertilizer additive.

The present invention relates to improving the efficacy of man-made and/or natural organic-based animal manure fertilizers by administration of an organic solvent formula containing polyorganic acids and/or their salts. The formulation liberates nutrient(s) that are normally bound in the soil as insoluble salts and complexes. These delivery formulations also provide an environmentally sound and inherently safe solvating system that improves diffusion of polyorganic acids to the granule fertilizer. These delivery formulations enable safe storage, transport and subsequent application or blending with solid or liquid fertilizers. The combined formulation and fertilizer can be applied to soil to provide improved efficacy of fertilizer by liberating nutrients bound in the soil for uptake by plant life.

The present disclosure relates to biodegradable materials and methods of removing using the biodegradable materials to remove phosphorus from water. Additionally, the biodegradable materials may be used as a fertilizer.

The present application relates to an iron impregnated biochar and its use as a fertilizer. The iron impregnated biochar of the present application has a ratio of iron (III) to iron (II) ranging from 5:1 to 10:1. The biochar may be produced by a method including treating the biomass with an iron (II) ion solution, pyrolyzing the iron (II)-treated biomass in an oxidative environment and recovering the biochar product from the pyrolyzed iron (II)-treated biomass.

A homogeneous fertilizer granule comprises slow-release (e.g. struvite) and fast release sources of phosphorus (P). The homogeneous fertilizer granule may further contain other essential nutrients and micronutrients required by plants. A number of methods may be used to make such granules. One method includes introducing a struvite slurry or fines and a liquid supply of water soluble P into a granulator. Alternatively, dry raw materials can be mixed with water/steam and/or another binder prior to being fed into a granulator. In another embodiment, pre-mixed dry raw materials are mechanically compacted and crushed to yield homogeneous fertilizer particles.

A method for granulating a slurry in a fluidized bed granulator having a main longitudinal direction from a seed end where granulation is initiated, to a product discharge end where granules are discharged from the fluidized bed granulator, including at least one fluidized bed compartment, an injection section and a granulation section, separated by a bottom plate including one or more injection nozzles, wherein a feed slurry is provided to the injection section, wherein a first fraction of the feed slurry provided to the injection section is injected into the granulation section through the one or more injection nozzles and a second fraction of the feed slurry, being the remainder of the feed slurry, is passed through the injection section without being injected into the granulation section. A fluidized bed granulator for the granulation of slurries for fertilizer products such as UAS according to the method of the invention.
