The evolutions of the world today and the population increase have resulted in pollution and human wastes, which contaminate the environment and adversely affect the human's quality of life. All forms of food and drink packages, made of paper, plastic foam, aluminum and glass, are designed for the consumers' convenience. After being used, these packages are discarded as garbage and have today become a social problem. It is in this context that our work for obtaining a building material (foam glass granules) that is much lighter is registered with the properties of heat insulation and acoustic improved based on cullet in order to recycle it and for improving the present laws about the waste products in dosed circuit (finished products -> waste products -> finished products). Investigations have shown that grinding waste glass to particle size less than 0.1 mm and adding 1% of Ca CO3 content provide the production of material with the following proper Lies: particle density of 0.5 g/cm(3), strength of 17.50 MPa and water adsorption of 95%, with the temperature for foaming ranges determined at 850 degrees C. The microstructures are homogenous, with pore sizes of up to 2 mm. The foam glass is counted among the new glass products meeting certain requirements on comfort, in particular in the building industry (thermal and acoustic insulation). The product obtained presents excellent thermal (lambda=:0,031 W/m degrees C) and acoustic (R = 15 dB) properties. (C) 2010 Elsevier B.V. All rights reserved.
