The aim of the present study is to assess the cost-effectiveness
of a 2S system in comparison to single stage (1S) alternative
processes. Three alternative 1S configurations (with electrostatic
precipitator as pre-dusting equipment, with fabric filter as
pre-dusting equipment, without pre-dusting equipment) all based
on the injection of NaHCO3, applied in several operating MSWI
systems, were selected as benchmarking technologies.
