Industrial re-use of non - friable plastic wastes has become a legal obligation and is a priority for environmental preservation . It must be economical in terms of production costs and energy expenses and it must be non-polluting. Because of the physical characteristics of non-friable plastics, an association of present methods of pulverization with cryogenic procedures is necessary to allow an economically feasible industrial exploitation . There is a world-wide need for a technological solution in this domain which corresponds to a market that goes beyond Europe. In order to reduce transportation between collection points and the transformation site, thus diminishing logistical consumption, equipment will be designed to be mobile .
