What You'll Learn
Plastic Identification Codes
In Australia, these Plastic Identification Codes play a pivotal role in the recycling process, impacting how plastics are processed and repurposed. However, there is confusion among Australians about what these codes mean and how to recycle effectively. To recycle correctly, it is essential to understand these codes and separate different types of plastics accordingly.
- PET (Polyethylene Terephthalate): This plastic is coded as 1 and is commonly used for soft drink and water bottles. It is easily recyclable and can be transformed into new bottles, containers, clothing, and even motor vehicle parts.
- HDPE (High-Density Polyethylene): HDPE is coded as 2 and is a hard, versatile plastic used for milk bottles, shampoo bottles, and cleaning products. It is readily accepted in curbside recycling and can be recycled into new containers, pipes, and outdoor furniture.
- PVC (Polyvinyl Chloride): Coded as 3, this hard, clear plastic is used for juice bottles. While recyclable, PVC recycling is limited due to its complex chemical composition and the use of various additives.
- LDPE (Low-Density Polyethylene): LDPE, coded as 4, is a soft, flexible plastic commonly found in plastic bags, squeeze bottles, and some food packaging. Although not all kerbside collections accept LDPE, it can be recycled into new packaging materials.
- PP: This plastic is gaining traction in recycling streams due to advancements in sorting technology. It is used for takeout containers, meat trays, and packing peanuts. PP can be recycled, but its acceptance in curbside recycling varies by location.
- PS: Polystyrene, often coded as 6, is another plastic that requires special handling and is not commonly accepted in kerbside recycling. However, engineers are working on developing better technologies to recycle polystyrene into new products like building materials.
- Other Plastics: The seventh group includes various plastics, such as biodegradable, compostable, and mixed plastics. This group also contains plastics that release toxins, such as those used for plastic cutlery and cosmetic packaging, which are not recommended for food use.
It is important to note that the coding system is not perfect, and the presence of a recycling symbol does not always indicate recyclability. Additionally, the use of Plastic Identification Codes is voluntary for manufacturers, so they may not be present on all items. Nevertheless, understanding these codes is a crucial step in improving recycling practices and reducing plastic pollution.

Soft plastics recycling
Australia generates roughly 76 million tonnes of plastic waste annually, with only a small portion of this being recycled. This has contributed to a growing problem of plastic pollution, which affects wildlife, marine ecosystems, and even human health.
Soft plastics, in particular, pose a challenge for recycling in Australia. While some soft plastics, such as LDPE (Low-Density Polyethylene), can be recycled into new packaging materials and plastic lumber, they are not always accepted in kerbside collections.
One option for recycling soft plastics in Australia is through supermarket collection programs. REDcycle, Australia's largest soft plastic collection program, operated through collection points at major supermarkets like Coles, Woolworths, and Aldi. However, REDcycle faced processing and recycling issues and collapsed in November 2022 due to a fire at its largest recycling facility.
The Australian government has recognized the need for a long-term national strategy to address soft plastic waste. The Soft Plastics Taskforce was established, and the Recycling Modernisation Fund was turbocharged with an additional $60 million budgeted for hard-to-recycle plastics.
Businesses can also play a role in soft plastics recycling. Companies like Cleanaway offer tailored solutions for businesses to identify their plastic waste types and provide customized bins and flexible collection services for soft plastics recycling.
It is important for Australians to understand the recycling codes and properly separate and clean their soft plastics to improve recycling rates and reduce the environmental impact of plastic waste.

Plastic waste impact
Plastic waste is a significant environmental threat in Australia, with around 76 million tonnes generated annually. The impact of this waste extends beyond littering landscapes; it affects wildlife, marine ecosystems, and even human health. Up to 145,000 tonnes of plastic will enter the environment every year, endangering marine life and entering the food chain.
Despite government policies aimed at creating a 'circular economy', only about 14% of plastic waste is kept out of landfills. This is due to a variety of factors, including the inefficiency, expense, and hazards of recycling plastic, as well as the low demand for recycled plastics. While Australia has released plans such as the 2018 National Waste Policy and the Australian Packaging Covenant, these focus on recovery and recycling rather than reducing plastic production and consumption.
The impact of plastic waste is not just about the environment; it's also about human health. Plastic pollution can enter the food chain, ending up on our plates. It is important for Australians to understand the nuances of plastic recycling to make informed decisions about plastic use and disposal. Educating people about the importance of recycling and how to do it properly is crucial. This includes teaching everyone to check the recycling codes, rinse their plastics, and separate them correctly.
Additionally, finding innovative ways to recycle plastics that are currently difficult to process is essential. Some companies are turning these tricky plastics into new products like building materials or furniture. As consumers, we can support these businesses and choose products with minimal plastic packaging. We can also opt for reusable alternatives, such as shopping bags, bottles, and cups, to reduce our plastic waste impact.
