Don't flush disposable products! Researchers Barry Orr and Darko Joksimovic are continuing their research on disposable products by checking product dispersion in sewers with this purpose-built to-scale sanitary sewer in the Urban Water wet lab!
Barry and Darko are studying variable flow and shear stress conditions on the dispersibility of flushable consumer products and their potential to reduce sewer blockages over time.
Initial findings show that plastic fibres and regenerated cellulose fibres are less dispersible than paper products. More data collection will be occurring over the coming weeks.
