Thank you for the answer, however, I still have some doubts.
Last year I got the access to ecoinvent database through Open LCA Nexus, OpenLCA Team sent me the following email.
"We received the login data for you from the database provider (ecoinvent), to give you access to the original files (not for openLCA) and background reports" in the mail I got the username and the password for academic free license for Educational user in a non-OECD country to get in to ecoinvent.
Reading again the email, I just notice that the access granted was just for the ecoinvent general files, not for using the database in OpenLCA. How can I download the inventory files for example "sodium silicate" to add it to the process in a openLCA database?
I need to run a LCA using OpenLCA and the database from ecoinvent, what should I do? Do I have to buy a special license or can I use the one I already have?
On the other hand, I read the handbook, section 4.4 Importing and combining databases, I did not see and explanation on how to convert ecoinvent files "2020-04-20_ecoSpold.spold.zip" to zolca.
