CChl is so assumed to be representative for the "CChl cluster", consisting of 17 categories (CChl, CChs, FAc, FEc, FNeu, HCT, HnCT, IRa, MEu, LOb, LTb, MRu, OLd, PMF, POf, TAc, WSc). For the sake of completeness , the outcomes of full and detailed LCIA are reported in the Supplementary Information Table . Results are reported in two forms: elementary flow perspective (histograms on the left) and process perspective (histograms on the right). This visualization allows to extrapolate and to better split the information and to get the relevance and importance of each phase of the system. Error bars plotting uncertainty ranges are included. The LS results highlight that the main contributor to the environmental impacts (93%, CChl) is the electricity consumption. Indeed, it represents the most relevant flow also for the other categories (except FEu), going from a minimum of 90.0% (LOb) to a maximum of 99.8% (WSc).
