Resumen
The advance in the technology of electronic devices stimulates the consumer market
to a constant exchange of equipment. The speed in obsolescence and the consequent
generation of electro-electronic waste imply serious concerns about the production and
consumption, since most of these products do not receive adequate post-consumer
treatment and are consequently deposited in landfills. Specific attention is needed to
balance production and the environment. An alternative to reduce the impacts
generated by the disposal of these materials is reuse of its components. Printed circuit
boards (PCBs) are pieces of electrical and electronic devices that are composed of
metallic, polymeric and ceramic materials. The metals have used in the printed circuit
boards, once separated, can be reused in mortars for civil construction, improving the
mechanical resistance. Thus, this work presents results of the composition through the
characterization of printed circuit boards ground in a knife-mill, leached with royal
water, analyzed by X-ray fluorescence (XRF) and finally the results were compared
with others in the literature.
