FLUIDIZED BED GASIFICATION OF SEWAGE SLUDGE: THE CASE STUDY OF CAMPANIA REGION

The potential of the fluidized bed gasification as a sustainable waste-to-fuel technology to handle the growing amount of sewage sludge (SS) generate from wastewater treatment plants located in the Campania region has been assessed in the present work. To this aim, the properties of SS relevant to its thermochemical conversion have been extensively investigated and the obtained results are briefly described in the present paper. Preliminary results from the gasification of SS in small-scale fluidized bed reactor are also presented and discussed, with a special focus on the composition of residual bottom ashes.
