Samenvatting:
Waste materials are increasingly being recycled as construction products instead of being landfilled. The recycling of waste materials into functional applications is beneficial from both an economical and environmental perspective, as it reduces the use of costly primary materials, while the need for space-consuming landfills and the associated long-term monitoring and aftercare is reduced. However, waste materials often contain increased levels of potentially toxic trace elements compared to natural materials such as soils. The potential environmental risk associated with the application of such waste materials in the environment (e.g., the application of incineration ashes in road bases or sound barriers) depends on many physical and chemical factors such as the application scenario (e.g., whether the material is exposed to rain- or groundwater), the contaminant concentration, its chemical form, toxicity, and ability to migrate towards vulnerable compartments such as soil and groundwater.
