Biomaterial exploration base on solid waste has been an attractive issue, particularly regarding economic and environmental demand. This work aimed to extract hydroxyapatite from snakehead fishbone through precipitation method and used to remove Ni(II). The hydroxyapatite product was characterized by using X-ray Diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscope-Energy Dispersive Spectroscopy (SEM-EDS) and Brunauer Emmett Teller (BET) method. Batch adsorption experiment includes pH solution, contact time and Ni(II) concentration. Pseudo-first order and pseudo-second-order were used to investigate the reaction mechanism and kinetic model, while adsorption equilibrium was evaluated according to Langmuir and Freundlich isotherm. XRD and FTIR spectra confirmed that hydroxyapatite was successfully extracted. The molar ratio (Ca/P) of hydroxyapatite was found at 1.70. The particle size of the hydroxyapatite was 48.77 nm. The pseudo-second-order is appropriate to describe the kinetic model while the adsorption mechanism follows Langmuir isotherm, which has an adsorption capacity of 5.359mg/g. The thermodynamic evaluation suggested the adsorption of Ni(II) is spontaneous in the endothermic process.

The nano‐structured hydroxyapatite was prepared from pig bone materials by mineralization. The obtained nano‐structured bone was much better compared to the bone without nanostructure for removing Pb2+. The process was investigated under different conditions including contact time, initial Pb2+ concentration, and pH. The pseudo‐second‐order kinetic model and Langmuir isotherm model were suitable for describing adsorption process. Moreover, the maximum adsorption capacities of nano‐structured bone and bone without nanostructure were 312.5 and 96.1 mg/g, respectively. Overall, the advantages of excellent adsorption capacity and simple mineralization together with low cost make nano‐structured bone an attractive material for removal of Pb2+ from aqueous solution.

“…Actually, this ABP is mainly inorganic (94% CaCO 3 ) [21] and its annual production may be higher than 350 thousand tons in Europe [22] which constitutes a relevant environmental issue. [23] Typically, raw ES has a low C/N ratio (≈2), mainly due to the organic content of protein, glycoprotein and proteoglycan fibers present therein. [24][25][26] Since ES is mainly an inorganic material, it may be expected that the energy released from the OM decomposition may not be sufficient to raise the temperature of the composting matrix to a thermophilic range adequate for pathogen inactivation.…”

Industrial eggshell (ES) is an animal by-product (ABP) involving some risk if not properly managed. Composting is a possible treatment approved for its safe use. This study aims to assess the influence of using N-rich material (grass clippings (GC)) to improve co-composting of ES mixtures for reaching sanitizing temperatures imposed by the ABP regulation from the European Union. Two sets of mixtures (M1 and M2) were investigated, each containing industrial potato peel waste, GC and rice husks at 3:1.9:1 and 3:0:1 ratios by wet weight. In each set, ES composition ranged from 0% to 30% (w/w). Co-composting trials were performed in self-heating reactors for 25 days, followed by maturation in piles. Results showed that only M1 trials attained temperatures higher than 70°C for nine consecutive hours, but N-losses by stripping on average were four- to five-fold higher than M2. In the absence of N-rich material, biodegradability of mixtures was 'low' to 'moderate' and organic matter conversion was impaired. Physical, chemical and phytotoxic properties of finished composts were suitable for soil improvement, but M1 took 54 more days to achieve maturity. In conclusion, co-composting ES with N-rich materials is important to assure the fulfilment of sanitizing requirements, avoiding any additional thermal treatment.
