- | The remarks below refer to production of cement clinkers and clinker grinding (only relevant as a source for particulate matter). The clinker-burning with intensive use of energy emits climate-relevant gases. CO₂ accounts for the great majority of these emissions, but heavy metals are important too. Information about the key source relevance can be found in [[[2-a-mineral-industry | 2.A Mineral Industry]]]. | + | The remarks below refer to production of cement clinkers and clinker grinding (only relevant as a source for particulate matter).

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.
