Types Of E-Waste
There are mainly 2 types of E-Waste which are classifieds according to the region specific which are generally global and urban mining.
They are explained below :
1. Global E-Waste
Globally, the world generates 50 million tons of e-waste annually. This value is equivalent to 6,000 Eiffel Towers and grows at about 5% each year. In 2016, Asia produced the largest amount of e-waste with 18.2 million tons, while America produced 11.3 million tons, Africa 2.2 million tons and Oceania 0.7 million tons.
2. Urban Mining
Urban mining is a trend today as higher quality material per ton than traditional metal ore mines. As urban societies continuously generate waste, 75% of the world's waste is generated from industrialized urban areas. These wastes contain more minerals and metals than primary sources. For example, sewage sludge has been found to contain more gold and copper than many mines.
