Dear all, I performed simulations for Biogas production in the Ecoinvent 2.2 and 3.1 databases. I find substantial difference in results. Main differences are in the impact categories "Terrestrial ecotoxicity" and "Freshwater aquatic ecotoxicity". In Ecoinvent 2.2 I used the process called "biogas, ...

Dear all,
I found out that the process called "treatment of manure and biowaste by anaerobic digestion" is the process I was looking for in Ecoinvent 3. Indeed the outputs of this process are biogas and digestor sludge.

Dear all, I am looking for raw biogas (55% CH4) in Ecoinvent 3, but the only flow I can find is "purified biogas", also called "biomethane", at 96% purity (96% CH4). In Ecoinvent 2, there is a flow called biogas (output of the process called "biogas, from biowaste, at storage"), but there is no info...

Dear all, I would like to assess a process using syngas (synthetic gas) as inflow. But I cannot find Hydrogen Production via Natural Gas Steam Reforming in the Ecoinvent 3 database. Hydrogen is used in refineries for desulfurization, but in the desulfurization process I find only Hydrogen from wood ...
