Cost-efficient and sustainable cleansing of PFAS-contaminated soils

Thanks to this partnership Milieutechniek de Vries & van de Wiel and Tauw, both soil experts, can now offer customers a total solution for washing PFAS's from sandy ground and granulate compounds.

Hybrid soil washing process

DEME Environmental has developed a ‘soil washing’ process that can be used to clean PFAS-based soils. It is a hybrid version of the wet extraction cleaning process which, besides separating fraction, primarily focuses on remediating process water. Cleaning yields of over 95% have been realised in the laboratory and in full scale applications.

Clean or apply for non-cleanable declaration?

However, it is expensive to dump PFAS-based soil (landfill levy) and it is certainly not sustainable or circular. Dumped soil is regarded as “waste”, while cleansed soil is given a second life. Valuable primary raw materials are also recovered when cleansed soil is reused.

The ‘DEME HYBRID SOIL WASHING PROCESS’ makes it possible to clean PFAS-based soil in a sustainable manner and to drastically reduce the amount of dumped material (by at least 60%).

Also suitable for you?
