The e-waste problem

The amount of electronic products discarded globally has skyrocketed recently, with 20-50 million tonnes generated every year. If such a huge figure is hard to imagine, think of it like this - if the estimated amount of e-waste generated every year would be put into containers on a train it would go once around the world.
The e-waste pollution

With the increase in the number of e-waste, the electronic pollution problem is more serious.E-waste is landfilled or incinerated, heavy metals penetrate the soil into rivers and groundwater, will result in the local soil and groundwater pollution, directly or indirectly, to the local residents and other biological damage; organics after incineration, releasing large amounts of harmful gases, such as the highly toxic dioxins, furans, polychlorinated biphenyls and other carcinogenic substances, the natural environment and human harm.


Electronic waste value

Bears significant business opportunities, "e-waste", the "dismantling" of the "electronic waste" containing gold, silver, copper, tin, chromium, platinum, palladium and other precious metals, will be an invaluable wealth.

Electronic waste contains metals, especially precious metals, its taste is several times of natural deposits or even hundreds of times, recovery costs are generally lower than the exploitation of natural deposits. For example, the old phone waste battery can extract 100g gold ordinary gold-bearing ore per ton can only extract 6g multi few tens of grams, can be said that the old phone is a very high-grade gold ore.So more and more driven by the interests of the company began recycling electronic waste, processed into the products they want.
