What Does It Really Mean?
Cutting Through the Confusion Around “Eco-Friendly” Claims in Cleaning Products
You’ve seen the claims:
“Biodegradable!” “Sustainable!” “Naturally Derived!” “Compostable!”
It sounds great — but what does sustainable really mean? And how can you tell what’s genuinely better for the planet and what’s just clever marketing?
In Australia, more consumers are choosing to shop consciously, but they’re also being bombarded with confusing eco-terms that aren’t always as green as they sound. Add to that the complexity of our national recycling systems, and it’s easy to see why many Aussies are unsure what to trust.
This guide breaks it all down: the terms, the packaging types, and the real challenges manufacturers face, plus the solutions many are turning to, like refillable options.
Eco Buzzwords in Packaging
What They Really Mean
Recyclable
✅ Can be processed and turned into something new, if your local recycling facility accepts it. Example: White PET #1 is technically recyclable, but due to low demand, there aren’t enough facilities to handle the process. Clear PET #1, on the other hand, is widely recycled.
Recycled
✅ Made from previously used materials (post or pre-consumer). Just saying “recycled” doesn’t reveal how much recycled content is in the product.
Biodegradable
✅ Will break down naturally over time into simpler compounds. This doesn’t mean it’s non-toxic or that it breaks down quickly. Some materials break down into microplastics, like plastic bags.
Compostable
✅ Will break down into organic matter without leaving harmful residues, under certain conditions. Most compostable plastics need industrial composting, which many Aussie councils don’t support.
Sustainable
✅ Suggests long-term environmental responsibility. There’s no universal definition; it often depends on context and can be vague.
Ingredient Claims Decoded
Naturally Derived
✅ Originates from natural sources like plants, minerals or other organisms like bacteria. Often, it has undergone a process to extract the ingredient, which is better than a petrochemical-based one.
Plant-Based
✅ Comes from plants instead of petroleum or animals. Doesn’t guarantee full biodegradability or low toxicity.
Non-Toxic
✅ Generally safe for humans and pets under normal use. Not a regulated term, it doesn’t always mean allergic reaction-free or safe for pets.
Organic
✅ Grown without synthetic pesticides or fertilisers. Only meaningful if it’s certified organic.
Biodegradable (again)
✅ Ingredients that break down safely and fully in the environment. An excellent feature for any rinse-off product.
Why Some Plastics Are Recycled and Others Aren’t?
Different types of plastic are handled differently depending on the material, colour, and local recycling capabilities:
- Clear PET #1 is highly recyclable and widely accepted across Australia.
- White or coloured PET #1 is far less recyclable due to contamination and limited demand.
- HDPE #2 (commonly used in cleaning bottles) is widely recyclable, particularly when it’s clear or uncoloured, such as translucent or frosted bottles.
- However, HDPE isn’t always suitable for formulas containing solvents or essential oils, as it can degrade or become brittle over time.
The Reality of Recycling in Australia
Despite our best intentions, the system has limitations:
- Soft plastics aren’t currently accepted in kerbside recycling bins. Read the common FAQs on soft plastic recycling found on the APCO website.
- Recycling programs differ by state what’s accepted in Victoria may not be in Queensland. Always check your local by using the ARL Logo Checker.
- Contamination is a big problem; food residue or incorrect sorting can cause entire batches to be sent to landfill.
- REDcycle (previously one of the largest soft plastic collection programs) remains on pause. However, trial programs are held in 44 locations across Australia.

Size Matters: Why Small Components Often Get Left Behind
When it comes to recycling, it’s not just what something is made of; it’s also how big it is.
Many bottle caps, pump heads, spray triggers, and other small parts are technically made from recyclable plastics like polypropylene (PP) or HDPE. But if they’re too small, they may never make it through the recycling process.
Here’s why:
- Small parts fall through sorting screens
In most Australian recycling facilities, items smaller than around 5cm x 5cm (roughly the size of a Post-it note) can fall through gaps in the sorting machinery and be lost to landfill. - Loose lids aren’t sorted the same way as bottles
Even if the plastic is recyclable, a detached cap or pump often gets sorted as general waste unless it’s attached securely to the bottle. - Lids can pop off during the crushing process, especially if the bottle has not been crushed and its lid replaced before placing it in the recycling bin.
- Mixed-material components are hard to process
A lid with a silicone seal or a spray trigger with metal springs adds complexity, and most facilities won’t separate them.
What Can You Do?
✅ Keep lids on bottles when placing them in the recycling bin. Remember to crush them as much as possible first
✅ Check the ARL (Australasian Recycling Label) on-pack; it will tell you if the lid should stay on or be removed
✅ Avoid packaging with multiple material types (e.g. plastic + metal + rubber) when you can
✅ Support brands using recyclable lids that stay attached or offer refill systems with reusable tops
In other words, even if it says “recyclable,” size and structure can still prevent it from being recycled. It’s another reason why designing with the end in mind is so essential and why bigger isn’t always better, but small can be a problem. The Australasian Recycling Label (ARL) was developed specifically to tackle this confusion by providing clear, evidence-based disposal instructions for each component of a product’s packaging. It helps brands design better and helps consumers recycle more accurately, but it only works when the packaging is labelled and local systems can support it.
Why Packaging Isn’t as Simple as It Looks: Manufacturer Challenges
For companies making products like cleaners, disinfectants, and sprays, choosing the right packaging isn’t just about sustainability — it’s about function, safety, and stability. Here’s why:
1. Formula Compatibility
Some formulas, especially those with essential oils, strong alkalis, or active ingredients, require packaging that won’t react, warp, or degrade. That rules out certain recycled plastics or less robust materials, such as HDPE.
2. Light Sensitivity
Some ingredients degrade when exposed to light, requiring opaque (solid colour/white) or coloured bottles, which, unfortunately, are harder to recycle.
3. Recycled Content Isn’t Always Viable (r=recycled)
rPET and rHDPE are in high demand globally. Sometimes, the quality, style of bottle and availability aren’t enough to meet demands, especially for packaging that needs to meet strict safety and regulatory requirements.
4. Functionality
Spray mechanisms, misting caps, child-safe lids — they all need to work reliably. Sustainable options are growing, but still limited in variety. Most sprays contain small components made from different materials, like glass beads, metal springs, making them non-recyclable.
5. Local Recycling Capabilities
Even the most “eco-friendly” packaging is meaningless if it isn’t recyclable in your local council area. Brands need to design packaging with real-world disposal in mind. Many local councils don’t have the facilities to support recycling of all packaging. Check your local area with the ARL recycling guide https://www.arl.org.au/
The Refillable Workaround: Real Sustainability in Action
Faced with the challenges of creating the perfect bottle. Finding one that’s recyclable, made from recycled content, chemically stable, and shelf-ready, many brands are now turning to a more flexible and sustainable solution: refill systems.
Instead of trying to solve everything in one bottle, companies are offering durable, reusable packaging supported by refill options.
Here’s why it’s gaining ground in Australia:
✅ Reduces plastic waste by up to 80%
✅ Avoids chemical compatibility issues by keeping durable outer bottles
✅ Lightweight refills = lower transport emissions
✅ Soft pouches use less material (though not widely recycled yet)
✅ Gives consumers an easy, low-waste option
Refill systems also make it easier for companies to offer eco improvements now, while the wider infrastructure for recycling and composting catches up.
Final Thoughts
What does sustainable really mean? When it comes to shopping sustainably, labels can be confusing, and greenwashing is a genuine concern.
However, by understanding what these terms mean and the trade-offs behind them, you can make more informed choices that genuinely support the planet.
Look for:
- Clear ingredient and packaging explanations
- Honest brands that acknowledge trade-offs
- Refillable or low-waste options
- Certification symbols (e.g. Australian Certified Organic, ARL logos, Australian Made)
Perfect packaging doesn’t exist, yet. However, by supporting companies that are making progress (not just making promises), you help push the industry in the right direction.
