Physico-Chemical Properties of the Pyrolytic Residue Obtained by Different Treatment Conditions of Meat and Bone Meal

The depletion of phosphate rock reserves has led to the search for new, alternative and environmentally friendly products processes. One safe sources is animal bone char (ABC), residue from pyrolysis meat meal (MBM), a slaughterhouse waste material. presented study investigated physico-chemical properties residues (ABC) obtained MBM under different treatment conditions. Two end temperatures (600 °C 1000 °C) five heating rates (5 min?1, 10 20 50 min?1 100 min?1) were used. ABC samples characterised by X-ray powder diffraction, IR spectroscopy, elemental CHNS analysis SEM/EDS analysis. results showed strong influence both temperature rate on morphology chemical composition final products.
