A modular process is provided for dismantling light automobile vehicles with a view to recovering their detached parts and recycling in an organized network. In each module the sum of the times of testing, conveyance, dismantling, recovery, sorting, packing and storing of the parts, pressing and evacuation of the carcasses, with respect to the number of vehicles treated, whatever their original state, remains constant over a determined period. A line is provided for conveying the light automobile vehicles and in this line stations for dismantling by batch of parts and not by unitary parts follow one another. Further logistics are provided for ensuring supply of each station depending on the demand of the operator independently of the operator of the preceding station.
