There is a dataset "soda bicarbonate" in the flows list of ecoinvent v.3.4 and it can be added to processes but there are neither providers, nor uses associated with this entry. If I use it in calculations, it does not form any contribution to the impacts. Also, I checked the ecoinvent database online and there is no such dataset (there are other similar - soda ash, etc.).
Is it an empty dataset deleted from older econvent versions or is it corrupted only in my downloaded zolca file?
