Harry Wooden is preventing the invasion of Sydney’s sewers by fatbergs – moist wipes that block sewers by creating strong balls of fats and human waste – utilizing stealth and science.
‘Flushable’ moist wipes clog Sydney sewerage
Cronulla Wastewater Remedy Plant is being congested with 2.5 tonnes of moist wipes from Sydney sewage each week.
The 12-yr-previous has cleaned up almost each prime science award for main faculty-aged youngsters together with his 27-web page analysis venture which in contrast the biodegradability of three massive model rest room wipes, that declare to be flushable, with rest room paper.
Now in Yr 7 at Mosman Excessive Faculty, Harry was one in every of 4 main faculty winners on this yr’s BHP Billiton Science and Engineering Award He gained for his 2015 investigation into the deterioration price of paper versus wipes: “Wipes vs Paper: Are flushable wipes what they are saying they’re?”
Now if he sees a packet of moist wipes claiming to be flushable on grocery store cabinets, he turns the packets round so consumers cannot see what they’re.
“Flushable wipes will flush, however environmentally they’re a catastrophe as they won’t biodegrade simply,” stated Harry.

Sydney Water stated many issues are flushable – toys and cell phones will journey round a rest room’s bend – however that does not imply they may deteriorate or degrade.
Flushable wipes are estimated to be liable for seventy five per cent of all blockages. The Australian Shopper and Competitors Fee can also be investigating a grievance by shopper group Selection, which is campaigning for these merchandise to be faraway from grocery store cabinets.
Sydney Water’s Keiran Smith stated seventy five per cent of all blockages have been brought on by moist wipes, which have been now used for all the things from eradicating make-up to cleansing kitchens and bottoms of all sizes.
“They should not say they’re flushable,” stated Harry.
“They need to say that if you’ll use them, it is best to put them within the bin and never down the bathroom to cease all of the fatbergs and the build up of wipes.
“Even placing them within the bin could be dangerous. They nonetheless take fairly a very long time to interrupt down.”
Over a two-month interval, Harry examined the biodegradability of three huge manufacturers’ flushable wipes and bathroom paper in 9 totally different circumstances together with recent, salt and native creek water and in several temperatures together with boiling water and refrigerated water.
He found that wipes deteriorate quickest in boiling water, though even then the speed was sluggish.

His analysis, undertaken in his final yr at Willoughby Public Faculty, was prompted by a presentation by Sydney Water at Taronga Park Zoo that confirmed how flushable wipes did not deteriorate once they have been agitated. Sydney Water estimates that one in 4 individuals in Sydney have been flushing moist wipes, with males the most important flushers.
Harry was shocked to seek out even his personal grandmother had flushed them . She’s since stopped.
His analysis found that wipes broke down quickest in boiling water whereas the speed was slowest for these wipes and bathroom paper floating in chilly water within the fridge.
As a result of the flushable wipes deteriorated so slowly, there was typically little for the younger scientist to report. His mom Megan Wooden stated Harry would verify the buckets each second day, and say, “I’ve obtained no outcomes, I’ve nothing to doc.”
Harry’s analysis challenge tracked the speed of decay over a two month interval, however he stored the samples for almost eight months, throughout which nothing a lot modified.
“Solely the bathroom paper had damaged down,” he stated.
Even the moist wipes that he’d positioned in compost have been intact eight months later, though the worms that when lived there appeared to have died as a result of the wipes blocked the oxygen, he stated.
“[The wipes] have been very black, however they nonetheless hadn’t damaged down.”
Sydney Water’s Keiran Smith stated Harry’s findings have been in keeping with analysis by water utilities.They confirmed each non-flushable and flushable wipes failed to interrupt down even after 20 hours of agitation in water.
He stated Harry’s analysis was one other reminder for individuals to cease flushing these merchandise as they will trigger critical injury to our community and to their very own sewer pipes at residence.
Along with the BHP Billiton Award for main faculty college students, the place Harry was considered one of 4 winners, he additionally gained a 2015 Younger Scientist Award and a 2015 award given to Younger Marine Scientists.
