Plastic Pipes and Chemicals

No chemicals of concern in plastic pipes

Chemicals are a fundamental part of everyday life and play an important role in our broader economy. In Australia alone, more than 40,000 industrial chemicals are available for use found in a wide range of products we interact with every day. While there are sometimes misconceptions regarding the industrial chemicals used to manufacture plastic pipes, it is important to note that the Australian Government’s Industrial Chemicals Roadmap states that most chemicals in use are of low concern to the environment and human health.

Australian plastic pipes are engineered to last providing the highest level of safety for our communities and the environment. There is a common perception that all plastics are the same, but Australian plastic pipes are made to some of the tightest standards in the world.

Our plastic piping systems provide reliable performance across all applications, free from harmful chemicals and compliant with Australian standards.

Drinking water safety

Plastic pipes provide the highest level of safety for carrying drinking water.

Harmful additives Excluded

Australian Standards for PVC pipe specifically exclude harmful additives such as phthalates, dioxins and heavy metals.

Plastic pipes do not contain PFAS

While PFAS are a high priority for environmental regulators they are not a concern for Australian plastic pipe systems.

No chemicals of concern

Plastic pipes do not contain any of the chemicals of concern identified by the Australian government through IChEMS

Australian plastic pipes don’t contain any phthalates or heavy metals

Health and environmental concerns sometimes associated with PVC do not apply to Australian-made PVC pipes, including PVC-U, PVC-M and PVC-O. This is verified through Best Environmental Practice PVC certification.

Phthalate-free

Unlike flexible PVC Australian plastic pipes are manufactured without the use of plasticisers.

Dioxin-controlled

Although dioxins were historically associated with PVC production strict modern manufacturing standards ensure they are eliminated from finished products. Emissions under best-practice processes are also significantly lower than those from many other common materials.

Heavy metal free

Lead, cadmium, mercury and hexavalent chromium are not used in the production of plastic pipes. Instead, safe calcium-zinc or organic stabilisers are used.

Best Environmental Practice PVC

Best Environmental Practice (BEP) PVC is a safer, more reliable and environmentally responsible approach to PVC production. It considers the entire lifecycle of the material from PVC resin production and additive selection through to manufacturing, use and end-of-life management.

PFAS and plastic pipes

While per- and polyfluoroalkyl substances (PFAS) are a high priority for environmental regulators they are not a concern for Australian plastic pipe systems. PIPA and its members are dedicated to ensuring our products remain safe, durable and sustainable for all Australians.

What are PFAS?

PFAS are a group of over 4,000 manufactured chemicals used since the 1950s for their ability to resist heat, stains, and water. Because some “long-chain” PFAS (such as PFOS and PFOA) are persistent in the environment and can bioaccumulate, they are being closely monitored and regulated by the Australian government.

You can be confident in the safety of Australian plastic pipes for the following reasons:

  • No PFAS used in manufacturing: Through rigorous consultation it has been confirmed that PFAS chemicals are not used in the manufacture of plastic pipes and fittings in Australia including Polyethylene (PE), Polypropylene (PP), PVC or PEX.
  • Safe components: This extends to all components of the system including lubricants used during pipe extrusion, moulded fittings and rubber ring lubricants.
  • Effective barrier against contamination: Independent research published in the Journal of the Australian Water Association concluded that it is unlikely for PFAS to permeate undamaged plastic pipes (HDPE and PVC) even if they are installed in contaminated soil or groundwater.

Environmental Management of Industrial Chemicals - IChEMS

Australian state and territory governments are working together to strengthen and harmonise the management of industrial chemicals and their potential environmental impacts. This national collaboration is guided by Australia’s Industrial Chemicals Roadmap which outlines the strategy for consistent effective management.

Read the roadmap here.

At the heart of these efforts is the Industrial Chemicals Environmental Management Standard (IChEMS). IChEMS is designed to:

  • Raise awareness about the environmental risks of industrial chemicals.
  • Improve regulatory consistency across Australia.
  • Promote shared responsibility between regulators and industry.
  • Align Australian frameworks with international environmental standards.

PIPA is actively collaborating with government on IChEMS as part of the consultation process for regulating industrial chemicals, ensuring the protection of communities and the environment.

Chemicals with the highest risk are subject to stricter controls ensuring that industrial activity is balanced with environmental protection.
