Each year about 7.6 million tons of waste glasses are landfilled without recycling, reclaiming or upcycling. Herein we have developed a solvent free upcycling method for recycled glass waste (RG) by remanufacturing it into porous recycled glass microspheres (PRGMs) with a view to explore removal of organic pollutants such as organic dyes. PRGMs were prepared via flame spheroidisation process and characterised using Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) and Mercury Intrusion Porosimetry (MIP) analysis. PRGMs exhibited 69% porosity with overall pore volume and pore area of 0.84 cm³/g and 8.6 cm²/g, respectively (from MIP) and a surface area of 8 m²/g. Acid red 88 (AR88) and Methylene blue (MB) were explored as a model source of pollutants. Results showed that removal of AR88 and MB by PRGMs was influenced by pH of the dye solution, PRGMs doses, and dye concentrations. From the batch process experiments, adsorption and coagulation processes were observed for AR88 dye whilst MB dye removal was attributed only to adsorption process. The maximum monolayer adsorption capacity (q_e) recorded for AR88, and MB were 78 mg/g and 20 mg/g, respectively. XPS and FTIR studies further confirmed that the adsorption process was due to electrostatic interaction and hydrogen bond formation. Furthermore, dye removal capacity of the PRGMs was also investigated for column adsorption process experiments. Based on the Thomas model, the calculated adsorption capacities at flow rates of 2.2 mL/min and 0.5 mL/min were 250 mg/g and 231 mg/g, respectively which were much higher than the batch scale Langmuir monolayer adsorption capacity (q_e) values. It is suggested that a synergistic effect of adsorption/coagulation followed by filtration processes was responsible for the higher adsorption capacities observed from the column adsorption studies. This study also demonstrated that PRGMs produced from recycled glass waste could directly be applied to the next cyclic experiment with similar dye removal capability. Thus, highlighting the circular economy scope of using waste inorganic materials for alternate applications such as pre-screening materials in wastewater treatment applications.

Bioactive glasses (BG) are heavily explored biomaterials especially for their bone and tissue regenerative property and biocompatibility. In this study, the synthesis of BG doped with Bi, Zn, and Cu (representative of Bi‐213, Cu‐64, and Zn‐65 radioisotopes) was investigated at 100°C via the sol‐gel method, followed by calcination at 700°C. Addition of dopants such as Bi, Zn, and Cu enhance the localized treatment of bone malignancies, aiming to combine therapeutic effects with enhanced mechanical integrity. The composition of the BG consisted roughly of 50% SiO ₂ , 25% Na ₂ O, and 25% CaO. X‐ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) were used to identify the crystalline phases and to determine the presence of specific functional groups in the BG, respectively. The XRD peaks demonstrated that Sodium Calcium Silicate (Devitrite) was present in the synthesized BG where highest intensity peak was observed at 2θ = 29.8°. A finite element analysis (FEA) was performed on the scaffold model with undoped BG properties to investigate the effect of blood pressure, which revealed minimal overall deformation averaging ∼0.12 Å, with edge deformation ranging from 1.58 to 0.635 Å. Furthermore, CFD analyses were conducted to explore the flow distribution through the microchannel network of the scaffold, which indicated favorable blood flow and pressure distribution throughout the BG.
