The method of obtaining hydroxyapatite by thermal treatment of deproteinised and defatted bone pulp called bone sludge was presented. The products of the calcining process were characterized with X-ray diffraction (XRD) and Fourier transformed infrared spectroscopy (FT-IR). The calcium content was determined with titration, whereas the contents of total phosphorus - with a spectrophotomertric method. X-ray investigations confirmed that hydroxyapatite was the main component of the calcining products in the calcining process. The FT-IR spectra confirmed that all organic substances were removed during the calcining process. On the basis of the research into physiological liquids the propensity to resorption of hydroxyapatite bioceramic was evaluated.

This paper presents the method of obtaining hydroxyapatite from animal bones. Bone sludge and calcined products were characterized by X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Calcium concentration was determined with titration, and phosphorus - spectrophotometrically. Making use of the AAS and ICP methods the content of microelements was determined. In all the products, hydroxyapatite was the only crystalline phase indicated. The FT-IR spectra confirmed that calcination removed the total of organic substances. Calcium and phosphorus contents were 38% and 18%, respectively, which corresponded to the Ca/P molar ratio of nonstoichiometric hydroxyapatite. The specific surfaces of products were measured by BET method. The volume of micro- and mesopores was determined.

W niniejszym artykule zostały przedstawione nowe możliwości wykorzystania miazgi kostnej, która należy do I kategorii odpadów według Rozporządzenia Parlamentu Europejskiego i Rady 1774/2003 z dnia 3 października 2002 r. Takim rozwiązaniem jest niewątpliwie spalanie odproteinowanej miazgi kostnej, zwanej mułkiem kostnym, a następnie zastosowanie popiołu z jej spalenia w temp. 600 i 950°C do produkcji ekstrakcyjnego kwasu fosforowego (43% P2O5). Podano również pełne charakterystyki surowców, półproduktów oraz produktu finalnego w postaci kwasu fosforowego i gipsu.

This article presents new possibility of using of bone sludge which belongs to I category of waste of a European Parliament and Council of Europe Decree no. 1774/2002 of 3 October 2002. The incineration of bone meal after deproteinisation (called bone sludge) could be a new solution. Ash can be use as a raw material to production of phosphoric acid (43% P2O5). The content of moisture, phosphorus and calcium, phase composition as well as the heat of combustion in studied samples have been marked.

This work presents the analysis of the waste from the meat industry. The bone sludge after the process of deproteinisation as well as the meat-bone meal have been the subject of the research. The content of moisture, phosphorus and calcium, the phase composition as well as the heat of combustion in the studied samples have been marked. The samples of the studied materials were incinerated at the temperature of 600°C for 3 hours, then the content of calcium and phosphorus in the obtained ashes was marked. The analysis was repeated for the ashes received from the combustion at the temperature of 950°C.
