Summary: The National Solid Waste Policy(NSWP) brought as one of the main guidelines the requirement implementation of municipal selective collection programs. Despite being essential, the municipalities are adapting and starting to implement their programs, but not all of them can reach the efficiency levels. In this work were used the selective collection modalities drop-off points, door-to-door, by Waste Pickers Organizations(WPO) and the use of more than one of those, called blended, to identify the influence that they have and the municipal selective waste collection efficiency. To analyze the influence of the modalities was used gravimetric compositions data of recyclable dry waste provided to WPO in 2017, from 55 municipalities from ES.
Besides that, were collected municipal selective waste collection route data, service frequency and the routine of the WPO, to create a database from which the work discussions were generated. Was identified the contribution in kg of the dry waste by selective collection modality in the year of 2017, being the blended modality with most contribution (58,5%) from the waste collected. Besides that, considering the research clipping, 55% of the population from ES was attended by the selective collection service. In terms of the service management there is a predominance in ES to use the WPO in the selective collection execution. Still, was identified the selective collection its nearly 2,5 times bigger than the conventional collection when executed by the WPOs and 4,4 times bigger when carried by third-party companies. Was possible identify the gravimetry composition from the dry waste collected in the ES, composed
by paper group and tetrapak with most participation (54%), followed by plastics (17%), residues (10%), glasses (9%), others (7%) e metal (3%). Furthermore, was calculated the medium per capita of 12,79 kg of dry waste collected/habitant fulfilled/year and 6,58 kg of dry waste collected/habitant total/year in ES in 2017. In the end, were realised statistics to emphasize the correlation between the sample data of the modalities considered.
