Análise do processo de regulação da atividade de triagem de materiais recicláveis: estudo de caso em uma cooperativa

Abstract

This dissertation discusses the construction of the operational methods in the conveyor belt of sorting recyclable materials in a collectors' cooperative. Cooperatives represent not only a way out of the problems of management of municipal solid waste, but also a possibility of integration and income generation for people who are outside the formal work. Nevertheless, the search for income and better life clashes with precarious working conditions. In this context, the aim of this study is to understand how the cooperative regulate their activity against the difficulties in the conveyor belt of sorting recyclable materials. The applied methodology includes a case study outlined by the Activity Ergonomics. The results indicate both an intense physical and mental effort associated with the collection of recyclable materials. During the activity, the cooperative members face few situations which may affect the objectives and regulate their activity without risking their internal state. Collective joints emerge from the conveyor belt as a possibility of collective regulation of the difficulties arising from the instantaneous overlapping variations (volume, variety and condition of materials) and ascending and descending requirements. These results indicate that the collection of recyclable materials is only possible through the inventiveness of the cooperative members to use perceptual exploration and solve problems facing the pace of work.
