  [ EN ] In recent years, recycling has become an unavoidable trend in the industrial field. Constrained by the current environmental situation and driven by the depletion of resources, industrialists are obliged to exploit the elements available to them as soon as possible in order to produce new values for development. In this context, the reuse of used motor oil remains an unexplored and promising field for research work, since used motor oil can be reused as a considerable source of heat energy that can be used to melt steel in a rotary kiln, a piece of equipment that burns it. An appropriate model of this equipment will be developed. The economic study allowing to set up a micro-steel plant requires an initial investment of 222.800.000 ariary with not only a ratio of added value and financial profitability respectively very high of 0,71 and 0,35 but also a margin rate on variable cost is high of 0,32.
