The objective of the present work is to present a physical characterization of the
polymeric wastes conducted in the conventional collection of the municipality of São Carlos, SP.
The method adopted for physical characterization was by sampling, where the number of
samples involved all of the sections, with the weight of each sample obtained by quartering.
Characterization was performed in the winter and another one in summer. The results that stand
out are the percentage of polymeric wastes, in weight of 10,47%, composed by PET (35,96%),
HDPE (26,42%), PP (16,25%), PS (7,96%), Other (7,85%), PVC (3,76%), and LDPE (1,79%). It
was observed that the percentage of polymeric wastes destined to the sanitary landfill is still
high, considering the existence of selective collection, and that the PET resin was considered the
largest in the participation index, overcoming PEAD, traditionally the one considered the most
abundant discard of household wastes.
