Abstract

The Energy Research Centre of the Netherlands (ECN) develops high-quality knowledge and technology for the transition to a sustainable energy management. Within ECN, the group environmental risk assessment focuses on the environmental risks associated with the (re)use of contaminated materials from energy production and waste to energy plants. The research is particularly aimed at the potential “leaching” of contaminants from materials. Leaching is defined as the release of contaminants as a result of contact with (rain)water, in which contaminants may dissolve. The environmental risk of contaminants present in a material is determined by the “leachable” fraction, as opposed to the (often large) fraction that is bound to the matrix in such a strong way that it will not be released. The assessment of the potential leaching of contaminants is of relevance for these waste materials that are increasingly being re-used as a construction product. After the leaching process, contaminants may be further transported through soil and groundwater. These transport processes are also subject of study in the group. The group has developed a generic approach for environmental risk assessment which is also applied to other policy fields, e.g. Construction products, contaminated soils, sludges and landfills. The presentation will give an overview of the environmental risk assessment approach. Examples of results and implications of the research will be addressed.
