Several sectors of Brazilian industry and commerce have destined their residues to be treated in homogenization and mixing units in the State of Rio de Janeiro known as blendeiras. The present study aims to outline a profile of the main characteristics of industrial waste that are sent to blending plants for treatment, aiming at their use as fuel and raw material in the production of clinker. The methodology consisted, first, in the search for documents that are part of the licensing and environmental control process in the licensing agency of these units. Based on the information obtained in the records of waste movements from the years 2010 to 2015, classification by origin was made, according to the state of the federation, by physical state, by quantity, by NBR ISO 10004, covering the class and type dangerousness and, finally, its potential usefulness in co-processing. The following were also recorded: the percentage of the main blending products and the destinations of the residues and tailings generated in the process. As a result, the following profile was obtained: the waste originates, mostly, in the State of São Paulo, through the port sector. Most of them are presented in solid state, and are classified as dangerous and toxic and will be used mainly for power generation. It is concluded that the outlined profile contributed significantly to the understanding of the toxicity of these residues and will serve as a basis for other studies that address the environmental and human health impacts in the co-processing chain.
