Dear Laura, have a good day.

I've been having issues to enter Umberto and I was hoping you, or any of the Umberto forum fellows could help me with some guidance.

The issue is the following.

As I try to authenticate my license to launch Umberto NXT LCA, a pop opens with the warning "The license key has exceeded its expiry date", after I accept this warning and close the authentication window, another pop up opens with the message "This version of Umberto NXT LCA has expired. Please contact ifu Hamburg at

I sent a mail to this adress and to support almost a week ago and they have not replied yet. I'm in a serious hurry to finish some models I have pending.

Now, I wonder if this issues answer to a version issue, and I should update my Umberto in order to regain access to it.

Beforehand thank you for your help.

Kind regards,


General / Problems calculating cml with a raw sugar model
« on: February 15, 2017, 18:48 »
Hi There,

I'm modeling the manufacture chain for non centrifuged sugar in Colombia. I have set up all the phases (8 processes) of my model and calculated the total flows in order to check its consistency, everything seems to be ok. But at the moment that I calculate cml, the inputs and outputs of the calculation don't take into account the materials used in several phases (processes) of my model. I don't know what to do to get a proper calculation of the potential impacts of this production chain, in which all of the materials are included.

Also, as the cooking of the raw sugar uses bagasse as a fuel, I have included the CO2 emissions of the combustion process as outputs of the processes that require heat, but as it seems, Umberto is not adding these emissions to the cml calculation. What should I do to have these values included in the calculations?

I do hope someone can help me.

Thanks a lot.
