In the German cement industry, dust separated from clinker burning exhaust gas is returned to the burning process. As a result, there is no need to take account of significant losses of particles via the exhaust-gas pathway. - On the other hand, particulate matter emissions occur during clinker grinding. | In the German cement industry, dust separated from clinker burning exhaust gas is returned to the burning process.

Emissions of HCB are not applicable according to a research result. The table of EF is related to two different AD sets. For purposes of the most pollutants the AD is burnt clinker. For purposes of emission estimation of PM the AD is grinded clinker (included further materials as domestic burnt clinker). NFR tables could provide only one AD (burnt clinker). | Emissions of HCB are not applicable according to a research result. The table of EF is related to two different AD sets.
