In recent years, the presence of noticeable occupational hazards in recycling sorting facilities has been pointed out in national and international literature. Most of these risks are credited to the poor quality of the separation carried out by the population, resulting in the sending of dirty and hazardous waste for the selective collection of recyclables. Damage to the health and safety of workers who handle such materials may arise if the structural conditions, technologies, work’s organizations and preventive measures adopted are not properly managed. Objectives: identify the occupational risk factors in two sorting facilities in the city of São Paulo; quantify injuries and diseases which had occurred before and during the study period; correlate risk factors with the injuries and diseases identified and recommend actions to minimize the damages to these workers’ health. Methodology: it is a multiple case study, exploratory, with quantitative-qualitative approach. It was initiated with a systematized review of the literature, focused on the health of recyclable waste pickers, covering two bibliographic databases in health science: PubMed and LILACS. Two sorting facilities were selected for this study after a preliminary survey of the situation in five cooperatives associated with the Selective Collection Program of the Municipality of São Paulo. The qualitative study incorporated data obtained through in situ observations and measurements, review of documents and focus groups with waste pickers. The quantitative data was collected through the application of a questionnaire and individualized clinical evaluation of the 83 participants of both cooperatives. Data obtained was integrated, analyzed and compared with other studies in Brazilian and foreign sorting facilities. Results: few improvements in working conditions were achieved by cooperative waste pickers working in recyclable sorting facilities compared to those acting in open dumps or streets. The level of productivity is low, as well as the consequent wages. They do not have the necessary background to give support in management, organization, or operations. Measures to promote health, prevention of accidents or diseases are punctual and minimal. Several risk factors (physical, chemical, biological, mechanical, accidental, ergonomic and psychosocial) were identified and correlated with diseases and accidents revealed by participants. The most frequent clinical manifestations were: musculoskeletal pain (77%), body injuries (48%) and respiratory problems (43%). Cuts or perforations were reported by 69% of the participants. Conclusion: some previously unknown and unexpected attitudes and risky operational practices have been revealed and certainly require immediate and indispensable interventions. The outcomes of this study are important in order to stimulate reflection, broaden discussions and contribute to decision-making in various spheres of management (health, welfare, work and environment), as well as serving to the interests and needs of workers and society.
