Accelerated carbonation of different size fractions of MSW IBA and the effect on leaching

•Degree of carbonation of IBA decreased as size increased.•This decrease is due to decreasing total Ca content and portlandite phase.•Percentage reduction in leaching did not correspond to degree of carbonation.•This reduction was attributed to decrease in pH and formation of secondary mineral.

Zusammenfassung:•Degree of carbonation of IBA decreased as size increased.•This decrease is due to decreasing total Ca content and portlandite phase.•Percentage reduction in leaching did not correspond to degree of carbonation.•This reduction was attributed to decrease in pH and formation of secondary mineral. Accelerated carbonation has been studied as a treatment method for MSW IBA, and the main advantage is that it can shorten the treatment duration from months to days, compared to natural weathering. This study investigated the effect of accelerated carbonation on different size fractions of IBA collected from two incineration plants in Singapore. The different size fractions were ground to
