Cement kiln - Wikipedia
The rotary kiln systems of the cement industry destroy these trace components virtually completely.  Polycyclic aromatic hydrocarbons (PAH) PAHs (according to EPA 610) in the exhaust gas of rotary kilns usually appear at a distribution dominated by naphthalene, which accounts for a share of more than 90% by mass. The rotary kiln systems of the cement industry destroy virtually completely the PAHs input via fuels.
