Release of pcdd/fs during a hydrothermal carbonization process of organic waste residues

In this paper the polychlorinated-dibenzo dioxins and furans (PCDD/Fs) release is analyzed during an hydrothermal carbonization process of the organic fraction of municipal solid waste (OFMSW). Two models to estimate the quantity of PCDD/Fs that can be released during this kind of process are presented in this paper. The first model follows a mass balance approach; the second one develops a phenomenon description based on the desorption mechanism. Finally, the effects of temperature and pressure on the whole yield of dioxins and furans are discussed.
