Transcripts

When you recycle glass you can make more glass, but  when you recycle plastic it's more complicated and  

the quality goes down each time. I mean you can  mix stuff with it like this fleece or even the  

carpet I'm on, but eventually it all ends up in  landfill or it's incinerated. So it's not really  

recycling, it's downcycling and you have to keep  making more and more new plastic which uses more  

and more fossil fuels. But a French company has  developed a way of recycling PET plastic so it  

doesn't lose quality. They get chopped-up plastic  from things like bottles plus clothes made from  

polyester, which get shredded. They then put them  into big vats along with water and some special  

enzymes. In a few hours they get broken down,  the additives can be removed and you're left  

with two substances which are the building  blocks for new PET plastic.

That represents 95  to 97% of the PET production in the world.

I mean the PET producers they use those two components  

but instead of having them petro sourced they would  have them recycled made from waste.

At the moment it's much more expensive to recycle plastic this  way but they're building a factory which will be  

able to process two billion plastic bottles  every year. So maybe recycling plastic will  

be as easy as recycling glass. I don't think  they're paying us enough for this you know.
