Chlorine input and chlorophenol emission in the lab-scale combustion of municipal solid waste

Article Abstract:

Emitted chlorophenols and HCI from a micromodel reactor mimicking the primary combustion chamber of a municipal solid waste (MSW) incinerator processing samples of regular and processed MSW were measured to examine the relationships between the origin of chlorine in the feed and the formation of products of incomplete combustion. An increase of the PVC load in the MSW resulted in a slight increase in the level of emitted chlorophenols (CP). CP emission level also does not change even with the replacement of the compostables and other important chlorine-carrying fractions by cellulose and NaCl.

Application of surface complexation precipitation modeling to contaminant leacing from weather municipal solid waste incinerator bottom ash

Article Abstract:

An applied surface complexation/precipitation modeling effectively described the leaching of contaminants from weathered municipal solid waste incinerator (MWSI) bottom ash. Results revealed that sorbent mineral and sorbate concentrations can be obtained by utilizing a combination of selective chemical extractions and leaching at pH values not ideal for sorption. Most model calculations were based on the Diffuse Layer Model and a database of sorption constants for hydrous ferric oxide.
