production of dolime from dolomite scrbid

Methodology for the free allocation of emission allowances ...

Lime and dolime differ significantly in process emission (0.785 t CO 2 / t lime and 0.913 t CO 2 / t dolime) and are different products, also from a chemical point of view. It is therefore proposed to develop separate benchmarks for lime and dolime at least for the process emission part of the benchmark.
