• In the high temperature environment in gasification, larger molecules such as plastics are completely broken down into the components of syngas which can be cleaned and processed before any further use.

  • Dioxins and furans need sufficient oxygen to form or re-form, the oxygen-deficient atmosphere in a gasifier does not provide the environment needed for dioxins and furans to form or reform.

  • Dioxins need fine metal particulates in the exhaust to reform; syngas from gasification is typically cleaned of particulates before being used.

  • In gasification facilities that use the syngas to produce downstream products like fuels, chemicals and fertilizers, the syngas is quickly quenched, so that there is not sufficient residence time in the temperature range where dioxins or furans could re-form.

  • When the syngas is primarily used as a fuel for making heat, it can be cleaned as necessary before combustion; this cannot occur in incineration.
