Are Flushable Wipes Actually Flushable? [2021 Update]
What was once relegated to infants and small children is becoming all the craze among adults across the globe. Nothing more than glorified baby wipes, adults around the world are singing the praises of wet wipes.
Many brands label their wet wipes as “flushable”, but how true is this? The answer to this isn’t a simple yes or no, unfortunately, and involves the ACCC, a legal battle and even touches on microplastics and their environmental impact.
Can You Flush Flushable Wipes Down the Toilet?
The marketing on the packaging might say “flushable”, indicating to you as a consumer that they’re safe to flush down your toilet. Your water service provider, however, probably has a different opinion.
According to Sydney Water, up to 75% of blockages involve wipes and they spend upwards of $8 million removing 500 tonnes of wet wipes every year. And this number is only growing!
Ever heard of a fatberg? Congealed masses of fats, grease and you guessed it, wet wipes are becoming an increasingly common problem in the wastewater system industry.
While machines can extract the bulk of the fatberg, workers still need to go in manually and remove what’s left over. This is the last thing workers in water services want to spend their day doing.
In light of all of this, we’d have to say that flushable wipes should not be flushed down the toilet. We recommend sticking to only flushing the “Three Ps”- pee, poo and (toilet) paper!
So if wastewater systems are struggling with the surge in use of flushable products, why are these wipes labelled “flushable”? That’s exactly why the Australian Competition and Consumer Commission (ACCC) launched a legal case against a number of flushable wipe companies, including Kimberly Clark and their Conttonelle Flushable Cleansing Cloths.
ACCC in Federal Court
Back in December of 2016, the ACCC took Kimberly Clark to Federal Court alleging that their “flushable” label on their Cottonelle Flushable Cleansing Cloths was false and misleading.
Flash forward to June 2019, the Federal Court dismissed the ACCC’s case, ruling that there was not sufficient evidence to suggest that these wipes in particular were the cause of the blockages in the sewerage system.
The ACCC appealed the decision but this was also dismissed a year later on the grounds that the blame for these blockages cannot be pinned on one sole company.
So does this mean it’s safe to flush flushable wipes? Not necessarily.
Consumer advocacy group CHOICE conducted a survey to assess how Australians understand the term “flushable” in the case of wipes. Of the 1679 people surveyed, 67% said they would expect flushable wipes to disintegrate just like toilet paper does which is not the case.
So where is the confusion coming from?
What Does Flushable Mean?
The term “flushable” isn’t actually regulated by any third party and so there is no one meaning for the word. In fact, the criteria many companies use to measure flushability is designed by flushable wipe manufacturers themselves.
According to SBS, flushable means it will pass through your plumbing system and into the wastewater systems. While this is good news for your plumbing, it still has great potential to cause blockages in the wider sewer system.
This is why the ACCC and CHOICE are advocating for more regulations around the word “flushable”.
Why Flushable Wipes Aren’t Flushable
When you flush toilet paper, the paper will lose strength when in contact with water and break down into small pieces. Broken down toilet paper has minimal risk attached to it.
While you might expect flushable wipes to lose strength and break down just like toilet paper and be safe for wastewater and plumbing systems, this simply isn’t the case.
CHOICE ran a test where they placed different wipes and toilet paper into water and agitated it for 20 hours. The toilet paper completely disintegrated in under three minutes. None of the wipes broke up for the entire 20 hours.
This test really highlights the problem caused by flushable wipes.
While flushable wipes pose a bigger problem for the wastewater industry, you’re not exempt from the problems as a consumer. Sydney Water received a report from one woman who had a $16,000 plumbing bill after flushing these so-called “flushable” wipes!
What About Biodegradable Flushable Wipes?
What about flushable wipes labelled as biodegradable? Surely these will break up! The answer here is still no – you should not flush biodegradable wipes down the toilet.
The benefit of biodegradable wipes is that instead of throwing them in your regular bin to be taken to a landfill, you can compost them! Because they’re made of natural materials, they will break down over time and are safe in the environment.
That doesn’t mean they will break up easily when flushed down the toilet and still risk blocking your toilet or sewerage system.
Are Baby Wipes Flushable?
No, baby wipes are not flushable. Baby wipes are designed just like regular flushable wipes to be durable so they can easily take care of your little one’s messes. This means they will no break down easily in your toilet and you’ll be risking a blocked toilet and all the messes that come along with that.
Flushable Wipes Environment
What about flushable wipes and the environment? If they cause a blockage in the sewerage system, this can lead to it overflowing and not only will the sewage escape into the environment, but the wipes will too.
This overflow has even reached the banks of our own water sources and wet wipes have been found near creeks! We’re all familiar with the awful effects of rubbish to our marine life, but have you considered their contribution to microplastics?
Microplastics are known to carry potentially harmful contaminants to our marine life and so there is ongoing research on how we can reduce them. A study in Ireland concluded that sanitary products, including wipes, are a bigger contributor to microplastics than previously thought.
The study tested marine sediments near wastewater treatment plants. Nearly all the microplastics found in these samples matched the fibres found in wipes and other sanitary products.
Worse yet, the researchers found that half of the flushable wipes they tested contained PET. This is a synthetic polymer often mixed with natural polymers, used for its good durability and strength. Strong and durable aren’t exactly the words you want to hear when describing something that should break down effortlessly in water. To be considered flushable, many think that only natural polymers such as cellulose should make up the wipe as these will break down more easily.
To make matters worse, many people flush non-flushable wipes! These are predominantly made with PET and so don’t readily break down. In fact, most of the microplastics found were attributed to non-flushable wipes.
This all goes to show that there needs to be greater public awareness about the proper disposal of wipes – both flushable and non-flushable – and the negative downstream effects if this isn’t followed. Better yet, the term “flushable” should be regulated by an independent party to better reflect what actually happens when you flush it down the toilet.
How to Dispose of Flushable Wipes
There’s only one way to correctly dispose of flushable wipes – in the bin! The same goes for any kind of wet wipe, in fact.
Properly disposing of your wipes is the best way to prevent wipe-related blockages in your plumbing system and further down the line in the sewerage system. There’s also the reduced chance of them ending up in our environment where they can do even more damage.
National Flushability Standard
Mid-2022 could see the introduction of a national flushability standard here in Australia. Urban Utilities removes approximately 120 tonnes of wet wipes from its network every year. In a world-first, this standard aims to work with manufacturers and utilities to establish what should and should not be flushed down the toilet.
The standard outlines seven clear criteria to ensure a product’s flushability which will land it a pass or fail result. The major test is how well it disintegrates between your home and the first pump station it will meet – so around 30-60 minutes.
With nine weeks of public comment beginning now, this national standard is on its way to being finalised. A spokesperson from Urban Utilities, Anna Hartley, had this to say, “right now consumers are being left in the dark without a national standard so it’ll mean shoppers will be able to make easier choices and do the right thing.”
How to Unclog Toilet Clogged with Flushable Wipes
If you do find yourself with a toilet clogged with flushable wipes, there are a few things you can do.
You can grab your plunger and plunge away at the blockage to dislodge it. While that might get rid of the wipe blockage for now, who knows how much might be building up in your pipes where you can’t see.
The best course of action is to get a professional plumber out for CCTV drain inspection and hydro jet drain cleaning. Not only will this clear the wipe blockage, but it will also leave your pipes cleaner than before you started!
