| Description
| - The investigation of the effect of moisture on the release and enrichment of heavy metals during pyrolysis of municipal solid waste (MSW) is essential. This is important due to: (i) the increasing amount of MSW per capita resulting in an increasing amount of metals in MSW, consequently leading to an enhancement of these metals in the solid product of pyrolysis beyond the normalized level; (ii) the effect of moisture on the overall cost of the pyrolysis process; and (iii) the utilization of the pyrolysis products. Seven metals were selected for evaluation and they included: As, Cd, Cr, Hg, Ni, Pb and V. The MSW samples with moisture contents of 0, 30, and 65 wt.% were investigated. In general, a diminution and an enhancement of metal content was observed for As, Cd, Hg, Ni, and V in both liquid and solid fractions of pyrolysis with an increase of the MSW moisture. A consistent trend was also observed for the relative enrichment index (REI) and release of heavy metals for the majority of metals investigated. That is, a reduction of REI and a release, ipso facto an increase of volatility, was observed for As, Cr, Cd, Ni, and V with an increase of the MSW moisture. Whereas, the inconsistent results were obtained for Pb and Hg. The effect of moisture on the REI and release was greater at the higher level of the MSW moisture (i.e. at 65 wt.%) than at the lower level (i.e. 30 wt.%) for Pb, and more remarkable at the lower lever of the MSW moisture than at the higher level for Hg. In summary, the results of this study demonstrate that drying of the MSW may not be a necessary requirement for the MSW management by pyrolysis, since an increase of the metals’ volatility enhances the removal of these metals from the solid product of pyrolysis and makes the process more suitable for commercial utilization.
