"Treating dirty waste water solves one environmental problem but creates
another by releasing large amounts of climate emissions. As microorganisms
break down sewage, they release carbon dioxide, methane and nitrous oxide –
three potent greenhouse gases.
Our new research found a surprisingly simple way to cut greenhouse gas
emissions from open wastewater treatment lagoons: growing plants on buoyant
rafts.
Water treatment companies have made progress in reducing emissions from their
operations, including switching to renewable energy. But the greenhouse gases
produced by the biological and chemical processes used to treat wastewater -
particularly in open treatment ponds - are harder to tackle.
The first, full-scale trial of its kind worldwide, our project on Phillip
Island in Victoria showed reductions in greenhouse gases by nearly a third over
two years."
