Residents living around the e-waste recycling sites, even if they do not involve in e-waste recycling activities, can also face the environmental exposure due to the food, water, and environmental contamination caused by e-waste, because they can easily contact to e-waste contaminated air, water, soil, dust, and food sources.
Computer monitors are typically packed into low stacks on wooden pallets for recycling and then shrink-wrapped. [1]Electronic waste recycling, electronics recycling, or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics; when referring to specific types of e-waste, the terms like computer recycling or mobile phone recycling may be used.
The recycling of electronic waste (e-waste) has seen significant technological advancements due to increasing environmental concerns and the growing volume of electronic product disposals. Traditional e-waste recycling methods, which often involve manual disassembly, expose workers to hazardous materials and are labor-intensive.

In the U.S. in 2011 only about 25% of e-waste was actually recycled.
When this is done on a large scale at an electronic waste recycling plant, component recovery can be achieved cost-effectively.

This e-waste often ends up in landfills, where it can leach harmful chemicals into the soil and water supply. [ 4 ] Another aspect of digital ecology is the energy consumption of digital technologies and the digital pollution in causes.
