Recycling wastes are a practical solution to reduce its detrimental effects. Many problems have arisen recently due to the rapid expansion on the quantity of waste. In this work, a practical solution was presented. The waste was mixed with wet clay to form a mixture that molded under pressure to form a wet brick. The wet bricks were entered into big ovens and during the firing process, porosity was induced inside them. The induced porosity enhanced the thermal insulation, decreasing the density, producing good brick durability with acceptable mechanical properties of the fired brick, in addition to that, a preservation in natural resources could be achieved. Following ASTM standards the values of the specific heat, dry density, thermal conductivity, cold and boiling absorption coefficient and both wet and dry compressive strength were measured with good accuracy.
