Given the complexity and challenges involving the recovery of recyclable materials from urban solid waste, especially paper/cardboard, this research aims to investigate how this activity develops in the Brazilian context. Therefore, the research explores a garbage sorting plant operated by a cooperative of waste pickers in Lençóis Paulista, State of São Paulo, where it develops such activity, in order to verify if the practice promotes environmental, social, and/or economic benefits, and if the paper/cardboard recovered is fit for recycling. This study seeks to understand the recovery process employed and the reason for using it; the representativeness of the paper/cardboard on the total mass of sorted waste and on the other recovered materials; types of paper/cardboard mostly recovered and the criteria used in this classification; general physical and chemical characteristics of paper/cardboard resulting from the process used. The method adopted was the exploratory study case and the investigation techniques used were: data collection, analysis files, interviews, observation, photographic records, physical artifact and laboratory analysis. It was found that the paper/cardboard was the most recovered material by weight, and the second that generated the most income for the cooperative pickers in the period analyzed. However, it was found that the process used in the recovery is extremely rudimentary, unhealthy and inefficient, and that the paper/cardboard extracted from waste is visibly dirty and damp. It was concluded that the activity promotes social benefits, providing jobs and income for a marginalized population; it contributes to the reduction of some municipal public spending, since it operated by the cooperative pickers; but leaves questions about the effectiveness of environmental benefits. In those observed conditions, it is unlikely that the recovered paper can be utilized as raw materia ...
