Avaliação ergonômica do processo de separação de materiais recicláveis utilizando um sistema modular estudo de caso em uma cooperativa de catadores do Estado do Rio de Janeiro.

Abstract

The separation sector (sorting) of recyclable materials of a cooperative located in the state of Rio de Janeiro was the object of this study aimed to conduct an ergonomic evaluation of the process of recyclable waste separation carried out by waste pickers, using a "modular system". The methodological procedures consisted of bibliographic research with survey state of the art, field observations using the Ergonomic Work Analysis (EWA) and schematic models of engineering of methods, and performing two experiments (station-rampa and station-bancada) using the strategy for mounting cyclegrams proposed in Analysis Decomposition in Steps (ADS). The analysis obtained from the results of two situations showed evidence that the current separation process at the rampa is deficient, time consuming and tiring, let the waste pickers with back and spine pain, and in addition there are many time losses in the transport of materials not adding value to products, due to the distance where are the containers for the packaging of the separated material The bancada module indicated to be the best alternative to the physical arrangement of separation, shortening the distances, suppressing some movements of the body (rotation and bending of the trunk), reducing the risk of spine injury. Different from the physical arrangement currently adopted, the station-bancada possible to reduce the average duration of the cycle and the frequency of extra activity cycle (EACs). The recommendations for improving the activity in the studied organization aimed at preserving the health and increase productivity. They were prepared, considering the physical arrangement, method of work and worker skills.
