Understanding Plastic Recycling Numbers

Ever wondered what those little numbers on your plastic containers mean? They're plastic identification codes, helping us sort recyclables! In New Zealand, understanding these codes can make a big difference in what gets recycled and what doesn't. It's a key step in reducing waste and helping our environment.

Let's focus on a few common ones. #1 (PET or PETE) is often found on drink bottles and some food containers; these are usually recyclable in NZ. #2 (HDPE) is used for milk bottles and cleaning product containers, and is also widely recycled. However, always check with your local council to confirm!

Plastic #5 (PP) appears on many food containers and some tubs. It's increasingly accepted for recycling, but again, check your local guidelines. Unfortunately, not all plastics are easily recycled. Numbers #3, #4, #6, and #7 often end up in landfills due to difficulties in the recycling process, or lack of facilities. By knowing what numbers are likely recyclable in your area – and choosing those plastics whenever possible – you're actively participating in creating a more circular economy. Reducing our reliance on single-use plastics in the first place is always best!
