Abstract Glass foams were successfully produced from discarded glass bottles (GB) and pine scales (PS) as pore former agent in contents between 1 and 50 vol%. Samples containing glass and pine scale wastes in powder form were homogenized and uniaxially pressed (20 MPa). The obtained powder compacts were dried (room temperature/24 h and 110 ºC/24 h), fired at 850 ºC/30 min/10 ºC/min and characterized according to their chemical, structural, mechanical, and thermal properties. The results (porosities between 78 and 86% with thermal conductivities between 0.072 and 0.093 W/mK and compressive mechanical strength between 0.2 and 3.4 MPa) indicated that the obtained foams produced from low-cost starting materials have potential for being used in applications where thermal insulation and non-flammability are the main technical requirements.
