Bone scaffold is a three-dimensional structure composed of materials that could enhance bone regeneration. Bone scaffolds were prepared using freeze-drying by varying the cockle shell powder concentration where sodium alginate acted as matrix. The scaffolds were then characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, texture analyzer, and liquid displacement method. The bioactivity of the scaffolds was evaluated by immersion into a simulated body fluid solution. Cockle shell powder concentrations affected the bone scaffold characteristics. The increment of the powder concentrations improved the physicochemical properties and bioactivity of the scaffolds.

“…Shells account for over 60% of the total product mass, of which only a small proportion is recycled as decorative materials, construction materials, and other low‐ or medium‐value materials. Most of the shells are discarded as a waste on road sides, abandoned ditches, and beach clearings, or reclaimed land (Morris et al, 2019; Saharudin et al, 2017; Saharudin et al, 2018). Dumping shells significantly wastes valuable resources because many components of the shells such as calcium carbonate (CaCO 3 ) can be recovered as value‐added products.…”

Conventionally, waste shells from aquaculture are dumped as a low‐value byproduct, which deteriorates ecosystems and threatens public health. Therefore, the reuse of waste shells is a pivotal issue. Calcination (≥700°C) can thermally convert calcium carbonate (CaCO3; the main component in waste shells) into active calcium oxide (CaO). This calcined shell powder has adsorption properties, antimicrobial properties, and biocompatibility, which can be used as a functional biofiller in food packaging. Calcined shell powder is also ecofriendly and nontoxic at the concentrations required for food processing and packaging, and has been approved as a food additive in Japan. Thus, this review comprehensively discusses the calcination process, compositions, adsorption and antimicrobial properties (and the underlying mechanisms), and applications of calcined shell powder in food processing and packaging.Practical applicationsThe active ingredient of calcined shell powder is active calcium oxide (CaO), which has functional abilities such as adsorption and antimicrobial properties, and is also ecofriendly and nontoxic to humans at the concentrations required for food processing and packaging. Its application as functional filler for food preservation and packaging films, the benefits, and the related mechanisms behind was the finding of this study.

“…Specifically, shell wastes such as oyster, mussel, scallop, clam and cockle are discarded in an abundant amount. Million tons of shell wastes have been discarded and piled up in landfills in China, Taiwan, Spain, South Korea, Peru, Indonesia, Nigeria, and Malaysia [4][5][6][7]. Instead, these shell wastes could be utilized to synthesize HA owing to the rich calcium carbonate (CaCO3) content [8][9][10].…”

Hydroxyapatite (HA) is a type of calcium phosphate-based bioactive ceramic that resembles the mineral phase of bone and teeth with great potential for bone substitution and biomedical implants. Biogenic-derived HA emerges as a cheap and eco-sustainable alternative to improve waste utilization. However, hydroxyapatite has limited applications due to its apparent brittleness, thus prompting investigation for enhanced sintering properties. In the present study, the combination of calcination and chemical precipitation technique was used to extract hydroxyapatite (HA) from ark clamshells (Anadara granosa). The method successfully produced HA powder with a Ca/P ratio of 1.6 and characteristic bands corresponded to pure HA via Fourier Transform Infrared Spectroscopy (FTIR). The synthesized HA powder was then sintered at temperatures ranging from 1200 °C to 1300 °C, followed by mechanical evaluation of the density, Vickers hardness, fracture toughness and grain size. It was revealed that the samples sintered at 1250 °C achieved a relative density of ~88%, Vickers hardness of 5.01 ± 0.39 GPa, fracture toughness of 0.88 ± 0.07 MPa.m1/2 and average grain size of ~3.7 µm. Overall, the results suggest that ark clamshell synthesized HA (ACS) had the potential to be used as functional bioceramics for biomedical applications. ABSTRAK: Hidroksiapatit (HA) adalah sejenis seramik bioaktif berasaskan kalsium fosfat yang menyerupai fasa mineral tulang dan gigi, berpotensi besar mengantikan tulang dalam implan bioperubatan. HA yang berasal dari biogenik muncul sebagai alternatif yang murah dan eko-lestari dalam menambah baik pengurusan sisa. Walau bagaimanapun, hidroksiapatit mempunyai aplikasi yang terhad kerana mempunyai kerapuhan yang ketara, menyebabkan penyelidikan diperlukan bagi meningkatkan sifat sintering. Gabungan teknik kalsinasi dan pemendakan kimia telah digunakan dalam kajian ini, bagi mengekstrak hidroksiapatit (HA) dari kulit kerang (Anadara granosa). Kaedah ini telah berjaya menghasilkan serbuk HA dengan nisbah 1.6 Ca/P dan jalur puncak sepadan dengan HA tulen melalui Spektroskopi Inframerah Transformasi Fourier (FTIR). Serbuk HA ini kemudian disinter pada suhu antara 1200 °C hingga 1300 °C, diikuti penilaian mekanikal pada ketumpatan, kekerasan Vickers, kerapuhan dan ukuran bijirin. Hasil ujian menunjukkan bahawa sampel yang disinter pada suhu 1250 °C mencapai ~88% ketumpatan relatif, kekerasan Vickers 5.01 ± 0.39 GPa, kerapuhan pada 0.88 ± 0.07 MPa.m1/2 dan purata ukuran butiran ~ 3.7 µm. Secara keseluruhan, dapatan menunjukkan bahawa kulit kerang HA yang disentisis (ACS) berpotensi sebagai bioseramik bagi aplikasi bioperubatan.
