POF is measured in non-methane volatile organic compounds equivalent (NMVOC eq). Comparably to OD, some studies did not consider POF. The standard scenario reached 3.98 kg of NMVOC equivalent per t of cement, against 11.8 kg of NMVOC found in this study. Again, the influence of transportation is evident and corresponds to the main cause of the difference. Excluding this step, POF is mainly affect by atmospheric emissions in the clinkering step and raw materials. In transportation, the contribution regarding the acquired clinker, considered as raw material, cannot be neglected.
