Resumen
Due to the accelerated development of new products and technologies and the planned obsolescence of consumer goods, electronic products are discarded increasingly earlier than expected, which creates the problem of proper disposal of the scrap. A considerable part of the whole electronic scrap is composed of printed circuit boards, which are largely composed of materials economically attractive, but that are difficult to discard because of the presence of toxic materials and heterogeneous composition. That is why the recycling of the printed circuit boards should be considered. This paper aims to presente the processes and recycling techniques such as: mechanical, pyrometallurgical, hydrometallurgical, biometallurgical and electrometallurgical. Finally, it presents a general model for evaluating the economic performance of printed circuit board recycling technic.
