Thank you for downloading this programme.

In this edition of the bottom line,

Evan Davis and guests talk about making money from second-hand mobile phones,

used engines and plastic bottles.

Hello, welcome to the programme.

Now think of all the stuff you discard.

Yesterday's newspapers, old clothes, electronics, cars even.

You may not give much thought to exactly what happens to it all.

It goes into a bin or a bag or you sell it and someone else has it before putting it in a bin or a bag.

Well, at some point it is dumped or recycled. And we're focusing on the recycling side of the equation

today, giving old products a new life. Of course, we all know that there

are environmental benefits to recycling, but we'll be true to the name of this program today

and focus on the bottom line. We'll hear from three businesses that have to conjure up value

out of the detritus of modern life. And let us start by taking a few minutes to meet

each of my three guests. And first, Charlo Carabot, who's co-founder of a company called Mazuma

Mobile. And, Charlie, what you sell is secondhand mobile phones. So just give us a sort of idea

of where you get them from and what you do with them.

We launched in 2007 and we targeted consumers that were upgrading their mobile phones.

Large majority of them were upgrading them because they just wanted the latest new tech.

So the large percent of them still worked and were perfectly fine. And we paid

customers for the handset. So they're simply going to their website, type in the model, find

how much it's worth. We send them a bag. They send it off to us. We process them so we test them.
