    摘要: This proposal propounds the development of granulated complex mineral fertilizers, coated with specific strains of the Rhizobium leguminosarum specie, for cereal crops. Carob gum is added, as an enhancer of the EPS native to the rhizobia, which renders them resistant to the unfavourable conditions of desiccation and high salinity caused by the granule of fertilizer. The pure culture of the Rhizobium leguminosarum strains in a medium, together with a blend of polysaccharides which have an enhancing effect on the production of exopolysaccharides by the rhizobia, for example carob gum or other blends having the same effect, is sprayed directly on the granules of fertilizer, followed by their subsequent air-drying.

    摘要: The present invention envisages a method for the recovery of phosphorus from waste incineration ash comprising a) a step of digesting the ashes with a 20-40% sulfuric acid solution, making a first solid phase and a first liquid phase, b) a step of continuously separating, without energy consumption, of the liquid and solid phases, c) a step of chemical precipitating, thermally coupled to the digesting of the ashes of step a), of the phosphate ions of the first liquid phase, by means of the addition of lime, until reaching a pH of 4.0-4.5, obtaining a second liquid phase, rich in acid, and a second solid phase, made up of phosphates and sulfates and d) a step of continuously separating, without energy consumption, of the second liquid and solid phase, the latter being the final product. Likewise, the installation for carrying out said method is envisaged.
