Negative Results for Resource Use
Posted: 11 Mar 2013 14:41
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?
