Scenario 2, the prevailing sub-stage in absolute terms in almost every impact category is palm cultivation in Malaysia, accounting for between 53.3% and 99.4% of the whole impact, except
in POCP (10.4%), ADP elements (23.6%), ADP fossil (30.4%) and ODP (33.1%). This is due to the use of pesticides and fertilizers, whereas GWP is almost entirely caused by the carbon uptake during palm cultivation. All impact values from this sub-stage are negative (except in GWP), since it appears subtracting in the system under study. With regard to GWP, palm oil extraction in Malaysia is also responsible of 30.6% of the impact. The prevailing sub-stage in the rest of categories is UCO ME production in Spain, causing 73.9% of the impact in ADP elements, 53.2% in ADP fossil and 42.1% in ODP, mainly because of the energy production, and the transport and production of the chemicals.
