Assessment of the consequences of a possible ban on phosphates in household detergents

Title:
Assessment of the consequences of a possible ban on phosphates in household detergents

Key Subjects in Danish:
Vaskemidler, fosfater, risikovurdering, renseanlæg

Abstract:
A screening and an initial risk assesment has been carried out for substances that may be introduced as alternatives if a restriction of the use of phosphates in household detergents is introduced. The results of the screening and the risk assessment indicate that a ban of phosphate in laundry detergents will not lead to toxic effects in the aquatic environment.

Effects on Danish wastewater treatment plants from a ban of phosphate will most likely result the in lower operation costs in terms of less use of precipitation chemicals and a lower sludge production. However expenses may be expected for modifications of processes and alterations of buildings and other constructions at the wastewater treatment plant.

Abstract in Danish:
Der er gennemført en screening og en indledende risikovurdering af stoffer, der kan anvendes som et alternativ, hvis der indføres et forbud mod fosfater i vaskemidler. Resultaterne af screeningen og risikovurderingen indikerer at et forbud mod fosfat i vaskemidler ikke vil føre til toksiske effekter i vandmiljøet.

Overordnet set vurderes den resulterende effekt på de danske renseanlæg at være en reduktion i renseanlæggenes driftsomkostninger som følge af et reduceret kemikalieforbrug samt en formentligt uændret slamproduktion. Der kan dog være udgifter forbundet med procesomlægning samt til- eller ombygning af renseanlæg.
