Estudo da dinâmica em uma central de triagem em Campo Largo - PR e entendimento de uma comunidade quanto à separação e valorização dos resíduos sólidos

Abstract

The objective of this work was to sensitize residents and students in a pilot community for proper separation, disposal and recovery of solid waste in order to improve working conditions and income of recyclable materials collectors from a sorting center. The main methodology was action research, which involved three stages: exploratory, action and evaluation. The working dynamics study in a sorting center based sensitization actions, in exploratory stage. The main link between the source of solid waste and recycling industries is a sorting center that is why this study is important. Moreover, perception diagnosis of separation and recycling of solid waste was made with residents and students in a pilot neighborhood. New study was done in the evaluation phase to find perception changes and to know if sensitization actions interfered in the sorting center bottlenecks diagnosed. The main results showed that steps of sorting and tailings are bottlenecks, suffering interference from domiciliary segregation and deficiency of reverse logistics systems for waste disposal. Sensitization actions with students and residents improved the perception of sending clean and dry recyclable materials to selective collection. Also improved the knowledge of an association of recyclable material collectors and the importance of devoting hazardous wastes such as fluorescent lamps, to resellers, decreasing the receipt of this kind of waste at the sorting center. The results will be used to support discussions with the producers chain toward sustainable waste disposal. Actions have already been replicated in the city throughout municipal and state schools, and homes served by the program of community health workers.
