Emission factor summary
The activity generating the emissions is market for anhydrite rock. The Reference Product is anhydrite rock. The product "anhydrite rock" represents the natural anhydrite rock, milled (comprising mostly of calcium sulphate, CaSO4). It is mined together with gypsum in open pit mining. The intermediate products are composed of about 65% natural gypsum (CaSO4 * 2 H2O), 34% natural anhydrite rock (CaSO4) and 1% soil and gravel that are deposited back in the mine. The material is gained by blasting and digging. The output of the mine is crushed and sorted. Anhydrite rock is used by the cement industry; it has to be finely ground for use as cast plaster floor. The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is market activity.
