Negative Results for Resource Use

Hi

I am doing an LCA of bio-composites and the environmental impacts from the choice of polymer (PP, PLA or bio-PE. For my resource use category, the impact turns out to be negative (the most negative for PP). When I make a product system, just comparing the polymers, the results are all positive. I cannot find any errors when looking at it, and neither can my supervisor. How do I solve this problem?

Hi Frida,

unfortunately I cannot help you with respect to your problem. However, there's an easy workaround: you can export the calculation results of your product system to excel (see screenshot attached). Then you can plot the bar chart in excel / libreOffice / ....

I believe it would just represent a little extra work, wouldn't it?

Best
