Evaluating the environmental consequences of landfilling or utilization of these residues, for example using life-cycle assessment (LCA) tools, makes it necessary to quantify the potential leaching from the residues according to the relevant disposal scenario. If the leaching potential is not estimated, a complete environmental assessment cannot be performed and potential future consequences cannot be accounted for. As such, quantification of potential longterm release of contaminants is an integral part of LCA on residue treatment and disposal
