With the basis on the M|G|? queue system it is modelled and analysed the idle motorcars dismantling and recycling process in a scarce conventional energy ambience. The model allows concluding that the dismantling or recycling time hazard rate function plays a key role in the process control. Moreover, through a cost-benefit analysis based on this model, it is possible to obtain criteria to evaluate the interest of the recycling and dismantling process or to compare the dismantling process against the recycling process.
