Notes:
In Italy, the amount of thermoplastic materials is 5 million tons. The recovery isnecessary through simple processes with high efficiency. The aim of this paper is to study the use ofplastic material particles in the ceramic industry for the production of light bricks, since this wasteburns during firing at high temperature. The clay is extracted by disused quarry of South Italy andthe PVC is a by-product of polymeric bars production (San Giovanni in Fiore- Calabria). The clayand the PVC waste were characterised by thermal analysis, X-ray diffraction to identify thecrystalline phases of raw material and EDS analyses to determine the chemical composition.Mixtures containing waste and clay materials were formed by extrusion and fired in a furnace usingrange temperatures of 900°C-1100°C. The obtained final products are bricks of 15 cm of length,2 cm of thickness and 1.2 cm of height. The physical and mechanical properties were studied. Theseproperties are used to define process firing temperature. Water absorption and linear shrinkage testscarried out as a function of the firing temperature
