For RCA-C, infrastructure does not exceed 3% of the total impact. In contrast, infrastructure has the largest influence on the total impact of NCA production. Regarding the NCA production, the contribution analysis shows that the production of NCA has stakes distributed in a greater number of stages than the recycling process.
