Considering the results (Fig. 3) after the redefinition of the
system boundaries, it can be affirmed that the process with the
greatest impact on climate change was energy consumption
(57.83% of total emissions), mainly related to the energy produced
from fossil sources. Second were the waste management processes
from different establishments (23.34% of total emissions). These
results suggest that Tetra Pak should focus on energy consumption
among its plants. These results are consistent with Tetra Pak’s
objectives and the company will perform direct interventions
regarding energetic efficiency and energy production from
renewable energy sources.
