Why is dumping e waste in landfills harmful to the environment?

When e-waste is warmed up, toxic chemicals are released into the air damaging the atmosphere. The damage to the atmosphere is one of the biggest environmental impacts from e-waste. When electronic waste is thrown away in landfills their toxic materials seep into groundwater, affecting both land and sea animals.

Why is e-waste dangerous to dispose of in a landfill?

Electronics are filled with chemicals and substances that are harmful to human health and the environment, including toxic metals, flame retardants, and persistent organic pollutants. If not recycled, these chemicals can contaminate landfills and enter the water supply through leachate.

Why is e-waste harmful to the environment?

After soil contamination, heavy metals from e-waste, such as mercury, lithium, lead and barium, then leak through the earth even further to reach groundwater. When these heavy metals reach groundwater, they eventually make their way into ponds, streams, rivers and lakes.

How do landfills damage the environment?

Air Pollution

About two-thirds of landfill waste contains biodegradable organic matter from households, business and industry. As this material decomposes, it releases methane gas. As a potent greenhouse gas, methane traps up to 20 times more heat in the atmosphere compared with carbon dioxide the EPA states.

How harmful is e-waste?

E-waste contains a laundry list of chemicals that are harmful to people and the environment, like: mercury, lead, beryllium, brominated flame retardants, and cadmium, i.e. stuff that sounds as bad as it is. When electronics are mishandled during disposal, these chemicals end up in our soil, water, and air.

What pollution does e-waste cause?

E-waste can cause serious environmental problems due to toxic chemicals such as lead, mercury and arsenic that pollute our soil and water and disrupt our ecosystems and our health.

How do landfills pollute water?

Dumps and landfills are a threat to water supplies when water percolates through waste, picking up a variety of substances such as metals, minerals, organic chemicals, bacteria, viruses, explosives, flammables, and other toxic materials.

Why are landfills good for the environment?

Reduce Greenhouse Gas Emissions

As a result, reducing methane emissions from MSW landfills is one of the best ways to achieve a near-term beneficial impact in mitigating global climate change. In addition, methane contributes to background tropospheric ozone levels as an ozone precursor.
