Corporate Responsibility in Practice: Co-processing …
291
It is currently spent per year to send ARLeV’s tailings to the landfill about
R$15,597.47. With the implementation of the co-processing project, it was found
that 73% of the material will no longer be allocated to the landfill. It will reduce the
costs of both transportation and landfill charges. From the calculations, it was found
that the total annual cost with the proposal would be R$2741.07. So, the city would
have a gain of R$12,856.39, equivalent to savings of 82%, only with the ARLeV
association. If the analysis were to expand to the 4 associations, the annual gain
would be about R$51,425.57. This analysis can be verified in Fig. 11.
It is possible to note that the gains correspond to transport (fuel) and the landfill
charges. Another requirement for the proposal to be implemented is that it will
be necessary for the material destined for Itambé to stay in a reserved place in a
separate container from the rest of the tailings that would be forwarded to landfill
