Smog into diamonds: unusual recycling schemes


New Zealand flooring company Cavalier Bremworth is about to start making carpet from fishing nets.

Nets are thought to make up 10 percent of all litter in our oceans and are known for killing seals, turtles, birds and even whales.

The company's working with Italian firm Econyl, which says every tonne of their recycled fish-net yarn can make 26,000 pairs of socks or 1000 square metres of carpet.

But they're not the only ones thinking out of the recyclable cardboard box.

A British company called Knowaste recycles nappies and turns them into plastics to make things like benches and roof tiles.

Here in New Zealand, we've got a lot of sheep, which means a lot of sheep poo.

A Welsh company, Sheep Poo Paper, takes that raw material then processes it until it can be crafted into sheets of paper.

An American non-profit actually collects donated pet fur, which is then used to make oil-absorbing booms, to use after an ocean spill. 

Those CDs and DVDs you've got lying around? Once crushed, cleaned and melted down, they can be used in car and building materials.

In one of the coolest examples of creative recycling, Los Angeles County collects and melts down five tonnes of seized or donated guns every year - some of which is turned into steel bars which reinforces concrete for road and bridge construction.

Finally, a Dutch artist has a plan to do something with China's smog troubles.  He's wants to make large towers that will suck up smog and then turn all that collected carbon into diamonds.
