On the other hand, the SUCP scenario shows higher impact reduction when compared with SU. In particular, employing the cold pressing technique instead than hydrodistillation the impact associated to the raw material decreases from 1.09 (73% of the direct impact) to 0.09 kg of CO2 eq/FU (18%) thanks to the consistently lower heat consumption during the virgin limonene manufacturing. This enforces again the role of the energy consumption on the environmental impacts of products. Similar considerations are valid for the FEu category, where the byproduct valorization choices showed an even higher influence of energy use on the final results, since the NPK substitution allows to abundantly compensate the environmental impacts, while the biogas conversion into electricity allows to reduce the direct impacts only of 0.26%.
