Hello everyone, I created the "Test tile production" database, then I imported the "Pet Bottle" database available for free. I created the "Test tile production" process and then I inserted all the products of the input as the raw material of the recipe for the production of ceramic tiles and as output the tile (1 ceramic tile - unit of measurement "item"). For the material and/or energy not present in the imported database, I created specific flows that I then added as input in my process.I can't calculate the impacts of the only process that I created using the existing database that I imported completely into my database that I called "Test tile production". If I try it doesn't return any impact. Regards
