A new study by Southern Cross University reveals that adult incontinence products are creating waste concerns with the products said to be a bigger waste problem than baby nappies.
The study involved the University of Queensland and was published in the journal Waste Management. It found that by 2030 waste from absorbent hygiene products (AHP) generated by adults will outnumber that produced by infants.
Lead author and environmental engineer Dr Emma Thompson Brewster of Southern Cross University says that while more AHP brands are presenting environmental-friendly marketing in Australia, all are sidestepping the elephant in the room.
“The burden on parents to choose the ‘best’ nappy product for their infants places unnecessary stress on many Australian parents, at a time while they are already experiencing the many stresses of raising small children,” she says.
“Used adult absorbent hygiene products (AHPs) receive far less public attention, but have a comparable or greater impact on our community health, environmental health and taxpayers.”
The research showed that while the waste from infant nappies will likely remain constant over the next decade, the waste from used AHPs will increase.
“This is due to the nation’s ageing population and associated age-related health conditions,” says Dr Thompson Bewster.
“While our expertise is on the waste management side of the problem, the trend highlights the heavily stigmatised issue of incontinence in the over-65 years population, which may have better solutions related to improved access to medical treatment like physiotherapy.”
Designed to contain human excreta (urine and faeces), AHPs for adults and babies are generally made of a combination of natural fibres, plastics, glues, and synthetic absorbent materials.
University of Queensland’s Professor Kate O’Brien has been investigating the environmental lifecycle of baby nappies for more than a decade.
“There’s lots of discussion about the environmental impact of babies’ nappies, but our study shows that adult absorbent hygiene products present a larger and faster-growing waste issue,” says Professor O’Brien.
“This study is about opening up the conversation to how we can better manage waste and consider other solutions going forward.”
