Fate of engineered nanomaterials in managed waste facilities
Managed waste facilities (“reactors”) act as crucial conduits for engineered nanomaterials (ENMs) prior to release to the environment . Key reactors include wastewater treatment plants, solid waste and dedicated sewage sludge incinerators, and landfills. Within each reactor, ENM can be physically (aggregation) and chemically (speciation) transformed, and the initial coating may be replaced by other substances (‘eco-corona’) or biologically degraded. The physical-chemical properties of the transformed ENMs are however are still very poorly investigated. Thus, the aim of this project is to establish transformation and release rates of ENM during their passage through different reactors.
