The recycling of chemical containing glass bottles is generally not recommended due to high health risk. In this study, used glass ampoules were devitrified into a porous material by coprocessing with eggshells, salt, and soda at different temperatures. In this thermochemical reaction, eggshells decomposed into calcium, porogenic gases, and char. The calcium worked as a flux in the reaction while char and gases promoted the porosity of the devitrified glass. The thermochemically processed glass was treated with deionized water to clear the water‐soluble fractions and to improve the surface porosity. The final product was characterized for its chemical composition, functional groups, surface morphology, and pore sizes. The porous product revealed the pore volume of .010 cc/g, surface area of 32.0399 m2/g and pore radius of 1.522 nm. The well‐known Freundlich and Longmuir models were used to investigate the adsorption of blue dye onto the prepared porous glass adsorbent. The adsorbed amount of dye was found influenced by the contact time, adsorbent dose, pH of solution, and dye concentration. The porous glass adsorbed about 2.788 mg/g of dye at pH 2, which decreased to 1.938 mg/g at pH 7. The dye adsorption data followed the best fit for Freundlich model as compared to the Longmuir model.

“…Glass is a highly stable material due to its vitreous nature and stable silicate backbone. The world produces 2.01 billion tons of solid waste annually, with at least 4–8% glass by weight. − Glass can be recovered from the solid waste in broken and nonbroken forms and sorted into various colors, such as flint, amber, and green. Sorting the waste glass by color increases its market value.…”

The objective of the presented work was to convert waste glass and mollusk shells into a porous material for separation of the direct blue 15 azo dye from industrial wastewater. The porous glass material of specific pore size and surface area was prepared through a thermochemical reaction by reacting waste glass with mollusk shells, soda, and rock salt. The optimal reaction conditions were determined by adjusting the reaction time, reaction temperature, and relative amount of the reactants. The surface morphology, elemental composition, and functional groups of the material were studied through scanning electron microscopy (SEM), X-ray florescence spectroscopy (XRF), energy-dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FT-IR). Barrett–Joyner–Halenda (BJH) and Brunauer–Emmett–Teller (BET) methods were used to determine the pore size distribution and surface area of the porous material. The material consisted of different types of flakes, oval-shaped particles, and granules. In addition to the functionalized char, the porous material contained Si–O–Si, Si–O–Al, and Si–OH groups. Relatively better yield and pore size distribution were obtained at a reaction temperature of 800 °C and reaction time of 90 min. The fully characterized material was used to separate the blue dye from industrial wastewater. This porous material absorbed about 2.66 mg/g blue dye from wastewater after 20 min of treatment time. The adsorption data fit the Freundlich isotherm better than the Langmuir isotherm. The correlation coefficient of Freundlich isotherm varied from 0.93 to 0.98, which was slightly higher than the correlation coefficient of Langmuir isotherm.
