The bottles are collected from a recycling bin. Always put your used bottles in a recycling bin.
The bottles are sorted at the recycling plant. There are seven different types of plastic, but most bottles are type PET 1 or PET 2 – these are put on the same pile.
Now the piles are sorted into colour – clear, green, blue or brown.
Once all the colours are sorted, the bottles are crushed by huge machines into big blocks of plastic.
The big blocks of PET 1 are broken down into small chips, which are then melted and poured through very small holes to make long threads. The threads make polyester (say polly-es-ter), which is used to make carpets for buildings and cars, clothes and sleeping bags. The chips are also used to make new plastic bottles. The PET 2 pile is used to make plastic shopping packets, milk bottles and plastic bins.
