proportion of tailings generated can be observed in Table 3. This quantity of tailings
represents 34% of the total waste received.
In addition to data collection within ARLeV, the information obtained with two
other previously conducted studies was used to compare and confirm the results. One
in Campo Largo itself, the ASSUR association and the other from an association
of Minas Gerais. According to Santos (2014), tailings represent 34% of the total
quantity of waste received by ASSUR association. And for Aguiar (2010), the average
percentage of tailings that the Minas Gerais association sends to landfills is 32.2%.
The results from both studies were similar to this study.
A big quantity of non-recyclables materials, such as organic, sanitary and
hazardous waste was found in the tailing sample. According to Santos (2014), this fact
is due to the generating source, which is incorrectly separating its waste, impacting the
rest of the recycling chain. Materials with recycling potential have also been observed
in the tailings, it may be there due to inaccuracy or carelessness in the screening
process or because they are not sold as recyclable materials by the association due
to several factors.
4.3 Current System Analysis
Through the weigh-ins performed in ARLeV association and the analysis of previous
studies conducted by Aguiar (2010) and Santos (2014), it was possible to verify that
