Is important to emphasize, however, that the way in which these elements are found in WEEE does not constitute direct dangerousness unless they are placed in contact with reagents or environmental conditions that provide the occurrence of chemical transformation. Those wastes can be classified as non-hazardous unless the existence of leaching tests proving the opposite for specific WEEE. In other words, the fact that a product has metals or other substances in its composition, does not necessarily imply the same be hazardous [11-12]. You need to know what state (physical, oxidation, etc.) these metals and other substances are found.
Electronics Takeback Coalition [13] stated that the WEEE produced until 2014, accounted for about 5% of the waste produced in the world, where computers and mobile phones in recent years would be occupying increasing percentage in this category of waste.
Based on the earlier information you can see that the global interest in WEEE in fact is not only in the prevention of potential environmental impacts of components, but the volume of e-waste produced and perhaps most importantly, the economic value that their components are providing opportunities to generate profit.
The mass of capital stored in appropriate places or inappropriate around the world and in a diffuse form resembles a field where exhaustible natural resources have very low concentrations causing it to be unattractive for exploration.
