I'm trying to input cellulose fibre boards for an LCA for a 3D printing process (As an approximate equivalent to UPM Formi 3D which is a cellulose fiber filled plastic composite). I have created a process with the reference flow as the product flow for fibre board production. I have made sure this is a product flow and I am using the free ELDC database.
The problem is that the provider options are blank, and so there is no contribution to the impact assessment from the material production. Is there any other reasons than this might be happening.
