What different types of plastic are there?

Plastic items usually carry a number which can tell you what type of plastic the item is made from and help you understand whether it can be recycled.
Plastic normally doesn’t contain a label saying ‘recyclable’ or ‘non-recyclable’, so you need to know what each number means.
Here’s a quick and easy explanation of what the different numbers mean and whether or not they can be recycled.
