Why You Should Recycle Your Mobile Phone

Your household probably has a few old cell phones lying around in a drawer – old models that got replaced when you upgraded. Most of us have some kind of ‘electronics graveyard’ of ancient phones, fried iPods and dead digital cameras in our homes.

Well, here’s a little something you probably didn’t know about these gadgets:

Nearly all of them are manufactured using a substance called Coltan, or Columbite-tantalite.  It is used to make many small electronics components, most notably the batteries.  80% of the world’s Coltan comes from the war-torn region of the Democratic Republic of the Congo (formerly Zaire), and I’m about to explain why you should do whatever you can to minimize your Coltan consumption.

Coltan – Just the Facts:

  • Most of the world’s Coltan comes from the DRC, where the average wage is $10 a month, yet the price of Coltan can go as high as $650 a kilogram
  • The Rwandan army, key instigators of the war in the Congo, made as much as $250 million selling Coltan in under 18 months, despite the fact that there is no Coltan in Rwanda
  • Coltan and other minerals used in cell phone batteries are recyclable, yet tend to end up in landfills where they can poison groundwater, crops, livestock and local residents
  • A recent UN report claimed that all parties involved in the war in the Congo have interests in Coltan mining, and derive a great deal of funding from its ‘systematic and extensive exploitation’ (source: http://www.cellular-news.com/coltan/)

In a nutshell, Coltan and other rare earth metals are the new blood diamonds.

A decade ago no one except geologists had heard of tantalum or ‘coltan’ – an obscure mineral that is an essential ingredient in mobile phones and laptops. Then, in 2000, reports began to leak out of Congo: of mines deep in the jungle where coltan was extracted in brutal conditions watched over by warlords. The United Nations sent a team to investigate, and its exposé of the relationship between violence and the exploitation of coltan and other natural resources contributed to a re-examination of scholarship on the motivations and strategies of armed groups.






There is a good chance that somebody was extorted, coerced or killed in order to get the minerals used to make your new iPhone. Profits from Coltan mining go directly to financing and equipping both sides in the conflict, extending it for years.  UN analysts have claimed that Coltan and oil exploitation are the main reasons that the war in the DRC continues to this day.

What’s worse is that the price of Coltan has recently slumped, leading to widespread unemployment, increased exploitation of local miners and a great deal less Coltan-derived money in circulation amongst the poorest people in the DRC. This means that miners have to work harder, for longer hours, in increasingly more dangerous war zones, to find enough Coltan to support their families.

The Alternative

It is very easy to recycle your old electronics. So easy, in fact, that there are a number of websites that will send you a free-post envelope for you to put your phone in, and then pay you cash directly into your bank account for your phone.  Unless it’s a relatively recent smart phone you won’t get much –$20 or so for a basic phone – but the point here isn’t really to make money.

What Happens to my Mobile?

  • Most phones will be refurbished and re-sold.  This is the least carbon-intensive and inexpensive way to recycle phones and electronics, and reduces the amount of Coltan consumed worldwide
  • If the phone is too old or damaged it can be dismantled and the rare earth metals used in its construction recycled, re-smelted and re-used.  This process is expensive, but carries a far lower cost in both carbon footprint and human suffering than mining and processing new Coltan.

Where Can I Send my Phone?

There are a number of companies who will send you a small amount of cash for your mobile, and recycle or re-use it.  Here are a few:

UK and Europe: http://www.envirofone.com

United States: http://www.recellular.com/

  2. okay this is good. i was wondering what i should do with my old/busted cellphones. i know they could be recycled but didn’t know where or how. now i do. thanks!

  3. I really didn’t care before how they make phones and other gadgets, or what elements are being used in the process. After reading this blog, I realized that how grave the situation regarding the element Coltan is. I don’t keep my old gadgets, I give them away. But I don’t know what happens to them after or what the new owners do with them if they got tired of them. This is really a great post. Thanks for this one.

  4. For youth generation this type of articles was totally bored but your article was fully different and realistic to the young generation for the future life. Good work man!
