New sampling methods for purifier sludge microplastics
Microplastics are under 5 mm in size. It has been estimated that more than 99% of microplastics are removed from water in municipal wastewater treatment plants, and large quantities of microplastics end up in sewage sludge. Now there are standardised methods for the characterisation of microplastics found in sewage sludge.
The Characterisation of Microplastics in Sewage Sludge project develops and validates sampling and characterisation methods for microplastics from sewage sludge and explores how selected sludge treatment processes affect microplastics.
The project also contributes to the following SDGs: 3, 13.
