摘要: Abstract This research explores the material recovery from bottom-ash, which is a residue municipal solid waste incineration. The investigations aimed to characterize, evaluate, categorize and classify development status of projects in Canton Zurich, including two technology pathways, i.e. dry wet bottom-ash recovery. temporal scale commenced with exploration phase 2003 concluded technological both operating commercial 2017. A retrospective view allowed identification enablers barriers that affected projects. Further perspective results be communicated United Nations Framework Classification for Resources (UNFC). investigation showed main trends. Firstly, project was mainly driven by knowledge increase regarding sampling metal characterization readiness effectiveness technologies changes legal financial environment. Secondly, amount recovered (dry matter content) increased about 6900 tons 16,500 2017, congruent an rate 5 14 percent per weight. In particular, elements recoverable economic environmental benefit, such as copper, gold silver, increased. Correspondingly, residual particular content disposable (fraction 2–16 mm) decreased
