Pollution of environments, besides diminishing a quality of water, directly affects a life of species that inhabit and depend on that ecosystem for its survival. The phytoremediation technique uses plants to remove pollutants present in the medium, absorbing and/or transforming in their tissues, and is a very useful alternative for decontamination of the medium. This process, however, generates large amounts of biomass due to rapid reproduction and development of plants, without treatment. As ceramic masses support an incorporation of industrial and urban waste, which have been added in adequate amounts, do not cause large variations of their goods. The use of waste in the manufacture of ceramics causes a reduction in the consumption of natural raw materials, so that this non-renewable resource becomes more durable. Currently, a waste incorporation in red ceramics is considered as an environmentally correct solution. In this research, the objective was to study the viability of the biomass of Eichhornia Crassipes, phytoremediate macrophyte, in the production of red ceramics. The characterization of the ceramic mass was carried out by means of chemical analysis by X - ray fluorescence, analysis of crystalline phases by X - ray diffraction and granulometric analysis by sieving and sedimentation. Compositions were prepared incorporating 0, 2.5, 5, 7.5 and 10% by weight of the biomass in the ceramic mass, homogenized in mill, moistened and shaped by vacuum extrusion, and fired from 650 to 1050°C. The apparent dry density, firing linear shrinkage and water absorption of the developed ceramics were determined. The results of this research are an incorporation of the biomass of Eichhornia Crassipes into mass ceramic, but a quantity should be controlled, not to harm as good of mass.
