What do plastic recycling numbers mean?

Recycling changes made easy.

Overview

When you buy something in plastic, producers should have a triangle with a number inside it. This indicates what type of plastic this is, and helps organisations like ours who deal with waste and recycling, to determine what is recyclable and what isn’t.

It can be really hard to tell from holding an item what it’s made of, and we know that can make recycling very confusing- but we love that you’ve come to this page to find out how to do the right thing.

We’re really proud to let you know that the significant portion of what you put in your recycling bin is recycled right here in NZ, and some of it here in the Manawatu-Whanganui Region

In the past, our mixed plastics have been recycled overseas, but currently no one is taking this type of plastic. We’ve been continuing to collect this recycling and have been storing it at the Awapuni Resource Recovery Centre. You can read more about this on our Recycling Changes page.

Here you will get a brief explanation of what the numbers are, what plastic materials they are, and what common items you use might be made of them. It also says where they currently go once we’ve emptied your wheelie bin.
