What Are PFAS? Why These “Forever Chemicals” Don’t Belong in Reusables
Worried about PFAS in food packaging? Here’s what you need to know about these harmful “forever chemicals” and how to avoid them in everyday life.
Quick Take: Are Grounded Goods Products PFAS-Free?
Yes, always have been, always will be.
All of our reusable cups and containers are:
-
PFAS-free
-
Made in Australia
-
Designed for closed-loop reuse
What Are PFAS?
PFAS stands for per- and polyfluoroalkyl substances—a group of over 4,000 human-made chemicals used to resist oil, water, grease, and heat.
The most infamous ones, PFOA and PFOS, have been used in everything from non-stick cookware to fast food wrappers. While some are being phased out, many are still used in everyday items.
They’re often called “forever chemicals” because they don’t break down naturally, and build up over time in soil, water, wildlife, and even in our bodies.
Where Are PFAS Found?
PFAS are used in products that need to repel water, oil or heat. You’ll find them in:
-
Non-stick pans and bakeware (especially older ones)
-
Non-reusable takeaway containers, pizza boxes and microwave popcorn bags
-
Compostable and paper food packaging labelled “grease-resistant”. Such as compostable coffee cups.
-
Water-resistant clothing and outdoor gear
-
Some dental floss, mascara, and other cosmetics
-
Firefighting foam
Are PFAS Dangerous in Food Packaging?
Yes, and that’s why we take it seriously. Studies have linked long-term PFAS exposure to:
-
Increased cancer risk
-
Hormone disruption
-
Immune system suppression
-
Liver and kidney damage
-
Low birth weight and developmental delays
-
Reduced vaccine response in children
The problem? PFAS can leach into your food, especially when heat or grease is involved.
Why PFAS Don’t Belong in Reusables
Reusable food and drink containers should be safe enough to use daily. Sadly, some products marketed as “reusable” or “eco” may still contain hidden PFAS or other toxic additives.
Grounded Goods: Safe. Smart. PFAS-Free.
At Grounded Goods, we make reusable packaging without compromise. That means:
-
No PFAS or harmful coatings
-
No hidden additives
-
Fully food-safe, durable materials
-
Locally made in Australia
-
End-of-life recycling through our closed-loop program
We help organisations, from cafés to hospitals, ditch disposables for good, without trading one health risk for another.
How to Avoid PFAS in Your Everyday Life
Here’s how you can steer clear of forever chemicals:
What to Do:
-
Choose trusted reusable containers made from food-safe plastics.
-
Use PFAS-free cookware, such as stainless steel, ceramic, or cast iron.
-
Read product labels and ask brands directly about chemical safety.
-
Switch to PFAS-free personal care items, like natural toothpaste, mascara, and floss.
What to Avoid:
-
Compostable takeaway items, such as containers or straws, unless they’re certified PFAS-free.
-
Non-stick pans unless clearly labelled PFAS-free.
-
Grease-resistant food wrappers are often used in takeaway or fast food packaging.
-
Waterproof mascara and dental floss with Teflon may contain PFAS compounds.
FAQs About PFAS and Reusable Packaging
Are all compostable containers PFAS-free?
Not necessarily. Many use PFAS to make them grease-proof. Always check for certifications or opt for reusables instead.
How can I safely switch to PFAS-free reusables?
Look for transparent brands, avoid greenwashing, and choose locally made, high-quality reusables with circular end-of-life options. When in doubt, ask about the brands you are using.
In Summary
PFAS are a group of synthetic chemicals that have become deeply embedded in everyday life, from food packaging and cookware to clothing and cosmetics. What makes them useful also makes them dangerous: they’re incredibly resistant to breakdown, meaning they persist in the environment and accumulate in our bodies over time.
Mounting research links PFAS exposure to serious health effects, including cancer, hormonal disruption, and immune system impairment. And because they’re often invisible and unlabelled, avoiding them can be difficult without education and transparency.
Understanding where PFAS are found and why they pose a risk is a critical first step in protecting yourself, your family, and the environment. As public awareness grows and regulation tightens, the demand for truly PFAS-free alternatives is only increasing.
The best defence? Stay informed, ask questions, and choose products that prioritise safety over shortcuts.
