Recycling of waste amber glass and porcine bone into fast sintered and high strength glass foams

Waste amber glass is primarily disposed into landfills, and only small proportions are reused or remelted. Recycling waste amber glass reduces the quantity of disposal and minimizes the potential environmental impact on landfill sites. This study adopts the fast sintering method and the concept of recycled materials in fabricating high strength glass foams: ceramic green body composed of pulverized waste amber glass and pork bone is sintered at 850 °C for 600 s. Prepared glass foam samples were thermally, structurally, and mechanically characterized to investigate the processing-property relationships. Particularly, high flexural strength values between 16.71 ± 1.73 and 29.69 ± 3.23 MPa were reported for glass foams prepared in this study. High strength glass foams prepared in present work is promising as a component in a variety of advanced structural and energy material systems, given their unique properties including heat insulation, sound absorption, and shock-wave absorption.
