This contribution shows the development of a waste removed from the dusting system of an EAF, aiming for its reincorporating in the industrial process by briquettes as energy source, beyond giving an environment improvement. The methodology was based on two groups of experiments and analysis. Being one part for experimental agglomeration, preliminary development, and finally, the part of the heats carried through in the company for analysis of the process efficiency. According to the positive results, it was concluded that exists the real possibility of making the briquetting using the developed method, that the quality of the briquette under the physical point of view takes care of the company demand and that its effect in the FEA also does not present problems about the chemistry of the steel, improving the draining of the slag.
