Sustainable Glass Foams Produced from Glass Bottles and Tobacco Residue

In this work, discarded soda-lime-silica glass bottles and tobacco residue (after oil extraction to produce biodiesel) were prepared in different formulations to obtain glass foams. The formulated compositions were homogenized and uniaxially compacted at 40 MPa then fired at 850 ºC and 900 ºC for 60 min to investigate the effects of tobacco residue and temperature in thermal and mechanical properties of the glass foams. The results show that glass foams obtained are promising materials for applications where thermal insulation and mechanical strength are desired, with values of 0.087 W.m-1K-...
