“…The calcium and phosphorus contents in MBM ashes (25-29 % Ca and 15-19 % P) were of the same order of magnitude with the average contents found in natural phosphate rocks (35 ± 2 % Ca and 15 ± 1 % P) [13].…”

“…The total production of MBM in the European Union (EU) exceeds 3,500,000 tons/year. The progressive restriction of the use of MBM in applications, such as animal feed [11] (except pet food [12]) has led to a significant increase in the amount of MBM to be eliminated [13].…”

“…Considering that MBM has a heating value ranging between 13 and 30 MJ/kg, incineration in a thermal plant could be one of the most appropriate methods to eliminate this residue [13]. However, incineration always produces ashes that must then be managed.…”

“…Thermal treatment of the entire production of MBM in Europe would then produce a large amount of ash (350,000-1000,000 tons/year). Therefore, the fate of such a stock of ashes is a major environmental concern [13].…”

“…Additionally, it was found that biogenic apatite (bone) had the largest apparent solubility after 12 days with a log(Ksp) of 45.2, compared with 57.0 for the mined rock phosphate and 48.0 for beneficiated phosphate rock [13].…”

Problem of decreasing resources of phosphate rock for phosphorus fertilizers production, can be mitigated by biological degradation of low quality substrates, performed by bacterial species able to produce mineral and low molecular organic acids. It was found that Bacillus megaterium was able to solubilize phosphorus incorporated with organic matter-biogenic apatite-bones. Using the microbial treatment (by acids produced by microorganisms) it was possible to produce liquid phosphorus fertilizers. At the same time the problem with utilization of noxious wastes can be solved. Two materials were used: bones and phosphorite. Two times higher solubilization factor for bones were achieved when compare to phosphorite. It was possible to obtain the organic liquid fertilizer with the content of P 2 O 5 0.09 % (m/m). It is necessary to evaluate the utilitarian properties of obtained fertilizer in the germination test.
