What PET is and why recovered PET matters for recycled-content manufacturing

For the Lazies - A 30-Second Summary

PET stands for polyethylene terephthalate, and it is one of the most commonly used plastics in the world. You will find it in drink bottles, food packaging, and even textiles. Recycling PET helps reduce landfill waste, conserve resources, and lower greenhouse gas emissions. It also supports the production of recycled PET or rPET, which is used in sustainable clothing, swimwear, and packaging.

What Is PET Plastic?

PET is a strong, and lightweight plastic most commonly used in single-use containers, such as water and soft drink bottles. It is labelled with the number 1 inside the recycling triangle symbol and is 100% recyclable.

Beyond bottles, PET is also used in packaging trays, fabrics, and other consumer goods. It is favoured for its strength, barrier properties, and resistance to water and bacteria.

Why Is PET Recycling Important?

Recycling PET helps reduce the volume of plastic sent to landfills. According to Australia’s Department of Climate Change, Environment, Energy and Water, Australians use around 3.5 million tonnes of plastic each year, and only 13 per cent is recycled.

PET that ends up in a landfill or nature can take hundreds of years to break down. It contributes to microplastic pollution and poses a threat to marine life. By recycling it, we give the material a second life and reduce the environmental damage caused by plastic waste.

From PET to rPET: Closing the Loop

Recycled PET or rPET is made by collecting and reprocessing used PET plastics. The material is cleaned, shredded, and melted into pellets, which are then turned into new products such as:

• Textiles, including activewear and swimwear

• Food and beverage containers

• Packaging and industrial materials

This process uses significantly less energy than producing virgin plastic, helping to lower carbon emissions. It also supports Australia’s circular economy goals.

How to Recycle PET Plastic Correctly

Here are a few quick tips for recycling PET plastic the right way:

• Look for the number 1 recycling symbol on the packaging

• Empty and rinse bottles and containers

• Remove caps where required, as they are often made of a different material

• Check local council guidelines to ensure PET is accepted in your bin

For many Perth residents, the yellow bin is the correct bin to ensure your plastic is being recycled. If you're a Mandurah resident, check out the recycling guide here.

Recycling PET may seem small, but when done collectively, it makes a big difference. Every bottle recycled is a step toward a cleaner, healthier Western Australia.
