The Department of Environment and Natural Resources (DENR) has called on the public for proper disposal of the so-called “electronic wastes,” noting the potential problems to the environment and human health.

In a statement, Environment Secretary Ramon Paje said that the public should practice recycling of e-wastes —including old tablets, smart phones, laptops and appliances—instead of just throwing them away.

He warned that e-wastes could have potentially toxic chemicals that can seep into the soil or water supply and escape into the air, posing danger to humans.

“If you happen to replace or simply have unused electronic gears or appliances sitting around the house, don’t just throw them in the trash. Many components of such equipment are considered toxic and are not biodegradable, and therefore can be harmful to the environment and human health if not disposed of properly,” he said.

The DENR chief noted some hard and sharp metals and toxic chemicals found in electronics, such as lead, chromium, nickel, zinc and mercury, can mix with other harmful substances in dump sites or sanitary landfills, posing even more danger.

“You have three main choices for properly getting rid of your old or unused electronics: trade it, donate it or recycle it,” Paje said.

He said that old electronic gadgets and appliances that are still working could be recycled by someone who is going to use them in a good way. For those who need money, he said that these items can be traded for extra bucks.

Paje said that those who are not hurting for cash may consider donating their old electronics.

“Gadgets like cell phones and laptops could be used to fund a good cause, or go to someone who perhaps wouldn’t otherwise be able to afford it.”

According to Paje, there are a number of ways people can do to recycle their old electronics without harming the environment. He said that there are electronic and mobile phone companies and recycling centers which collect e-waste.
