In this is inventory results of the process: citric acid production | citric acid | Cutoff, S
I checked and there are 3 land use inventories that get flipped. (from input become output with a negative sign) after calculation is run
- Occupation, dump site
- Transformation, to forest, unspecified
- Transformation, to dump site
looking at the process inventory and then to the "inventory results" after calculation these flows from input do become outputs with a negative sign.
This is causing some issues in Land Use Methods I am calculating from Ecoinvent DB. while in the system process this is causing negligible changes in complex unit tree systems this difference is quite high.
I am using a dedicated python script to run multiple calculation and comparing them with what I get from open LCA. I get results that are equal openLCA to all indicators but not land use that is exploiting the natural flows mentioned above.
I am unsure why this flips happen and if this is the correct calculation behavior or not. it seems to me it is not. but in case then in Open LCA all LCIA methods usoing the land use flows are not computing properly
Looking forward to hearing from you
thank you in advance
