【 摘 要 】

The ornamental rock industry generates hugeamounts of wastes during the process of extraction and sawing of rock blocks.The ornamental rock powder waste is a non-biodegradable material, which representsthe increase in environmental problem. The waste was collected from a graniticrock sawing plant located in Santo Antônio de Pádua, Rio de Janeiro.The chemical-environmental characterization and classification of the wastewere done according to ABNT standards. The results showed that the graniticrock powder waste should be classified as Class II A – "No Inert",because of its high concentrations of lead, chrome, iron and manganese.
