Effect of carbonation on the leaching of organic carbon and of copper from MSWI bottom ash

Characteristics and application potential of municipal solid waste incineration (MSWI) bottom ashes from two waste-to-energy plants

“…Hence, if a water washing treatment is applied to reduce the amount of Sb in bottom ash, it could be expected that BAW would have a better washing efficiency. According to previous research, the leaching of copper from MSWI bottom ash is related to the organic matter content [72]. Hence, the slightly higher leachability of copper in BAW than in BAM could be explained as a result of a higher amount of organic matter.…”

Automotive shredder residue (ASR): Reviewing its production from end-of-life vehicles (ELVs) and its recycling, energy or chemicals’ valorisation

“…A possible way to decrease copper leaching below the limit value, is extraction with solutions of organic complexants, like ammonium citrate, or acid washing with dilute HCl solutions [123,124]. Another possibility is heating the bottom ashes (at about 400 • C) in order to destroy fulvic and humic acids that form extractable complexes with copper [71,125].…”

Effect of short-term natural weathering on MSWI and wood waste bottom ash leaching behaviour

“…When an ash treatment method must be chosen, much attention must be payed to investments and operating costs. In EU countries natural weathering of BA for 6-12 weeks after quenching is the most commonly employed method [29,32,13,[33][34][35].…”
