Bioactive calcium silicate glass synthesized from sustainable biomass wastes

Abstract

Biomass wastes of corn, sugarcane, and eggshells were used as resources to synthesize calcium silicate glass by applying the melt quench technique. The glasses were characterized by different experimental techniques to check their suitability as bioproducts. The in vitro bioactive properties of the glasses were evaluated in simulated body fluid (SBF). As confirmed by X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy, a carbonated amorphous hydroxyapatite layer was formed on the surface of the glass. The ions released from the glasses into SBF were analyzed by microwave plasma atomic emission spectroscopy. The dissolution rate of the glass increased with increasing proportion of eggshell powder in it. The Ca/P molar ratio for all the glasses was in the range of 1.78 to 4.1. These bioactive glasses formed carbonated amorphous hydroxyapatite, which can be used to enhance the osteointegration rate in the human body. Bio-food wastes are a sustainable, environmentfriendly and cost-effective source for the synthesis of different types of bioproducts.

Bioactivity and Biocompatibility Properties of Sustainable Wollastonite Bioceramics from Rice Husk Ash/Rice Straw Ash: A Review

“…Shivani and Kulvir (2020) [ 25 ] produced bioactive calcium silicate glass using a melt-quenching technique. The precursors were from sugar bagasse and corn for the silica source and eggshells for the CaO source.…”

“…The use of biomass as a renewable energy source, or for the production of biogenic materials—especially from rice husk and rice straw—has sparked a lot of interest in recent years [ 14 , 15 , 16 ]. Previous studies reported that agricultural waste is a safe substitute used as bioceramics or bioglass [ 17 , 18 , 19 ], biomaterials in bone substitution to stimulate osteoblast development [ 10 ] in medical and dental therapy [ 20 , 21 , 22 , 23 , 24 , 25 ], and anticancer drug delivery [ 26 ].…”

Calcium Glycerolate Catalyst Derived from Eggshell Waste for Cyclopentadecanolide Synthesis

“…Hence, it is not desirable to landfill eggshell waste directly due to environmental concerns. Instead, eggshell waste can be potentially reused to eliminate the environmental threat and produce a high economic value ( Xu et al, 2019 ; Mohazzab et al, 2020 ; Punj and Singh, 2020 ).…”

Photoluminescence and structural properties of air‐reduced rare‐earth (Eu) doped calcium silicates derived using biomass wastes

“…These ash-derived materials are being utilized to synthesize phosphors that can be probable candidates for solid state-lighting applications. 8 The ashes of biomass waste are also being used to produce bioactive glasses, 9 glass sealants, 10 and dielectric materials. 11 Biochar prepared from biomasses can be used as an adsorbent for the treatment of wastewater containing methylene blue dye.…”
