Have you ever wondered what the number in a triangle of arrows on the bottom of a plastic bottle or tub means?
Plastic is divided into seven categories and the numbers show how the plastic can be recycled. The vast majority of plastic is made from oil so there's never been a greater need to recycle rather than send it to landfill.
What the numbers mean
Polyethylene terephthalate (PET or PETE). This plastic is often used for fizzy pop bottles and ready-meal containers.
High-density polyethylene (HDPE). This number is usually found on plastic milk bottles, my bottle of washing-up liquid has it stamped on the bottom.
Polyvinyl chloride (PVC). Clingfilm, shampoo bottles and toys can be made out of this plastic. And dodgy trousers.
Low density polyethylene (LDPE). This is thin plastic like carrier bags and bin liners. It can rip easily which is why most plastic bags can only be used once.
Polypropylene (PP). My Chinese takeaway boxes have this number on the bottom. Don't worry, I reuse them to store ribbons and buttons!
Polystyrene (PS). Yoghurt pots, egg cartons, vending cups and the plastic used to package electronic goods are all made from polystyrene.
This number is used for any other plastic that doesn't fit into one of the categories above.
Not all plastics can be recycled by every UK council so it's worth finding out what your council can take.
Interesting fact - PET bottles can be recycled into clothing. The plastic is broken down into little pieces and then spun into thread. This, quite remarkably, can then be used to make trousers, shirts, jackets, the list goes on. According to www.wasteonline.org.uk, it takes 25 bottles to make an adult's fleece! Check out www.recyclenow.com, it has lots of useful info on all kinds of recycling.
