title: Eco-efficiency assessment of options for metal recovery from incineration residues: a conceptual framework.
abstract: Residues from municipal solid waste (MSW) incineration in Switzerland have been a hot topic in recent years, both in the research and practice communities. Regarded by many as an economically and environmentally sound solution to this issue, technological retrofitting of existing grate incinerators has the dual purpose of enhancing the metal recovery of bottom and fly ashes and improving the inertization of residues to be landfilled. How does context influence the economic and environmental performance of this particular technological option? Under which conditions would this technological option be implemented nationwide in the future? What are stakeholders' views on sustainable transitions of MSW incineration? We propose a three-stage methodological procedure to address these questions.
