I am running openLCA 1.10.3 and have a license for ecoinvent 3.8. I've recently come across the US government LCA Commons which has processes/product systems particular to Lime and Gypsum Manufacturing. (See here https://www.lcacommons.gov/
After downloading a few of these product systems I realized that some of the flows do not have providers. Some flows start with the word CUTOFF which I think mean that they have no provider. I was on the openLCA nexus, and saw that you can purchase and download the LCA commons linked to ecoinvent 3.5, but it costs 500 EURO. .
I already have a license to ecoinvent -- so is there some way that I can easily link these databases? Would it be best to access the LCA commons through the collaboration server? Under documents at this link https://nexus.openlca.org/database/LCA%20Commons%20(complete)
it has some information on "connection with ecoinvent (version 3.5)" this outlines how some of the missing providers were connected to ecoinvent.
Any info would be greatly appreciated! Many thanks!
