[The sorting of recyclable waste and the variables inherent to the process: a case study in a cooperative]. / A triagem de materiais recicláveis e as variabilidades inerentes ao processo: estudo de caso em uma cooperativa.

Informal labor with recyclable materials is marked by social exclusion and discrimination, besides this activity being conducted in unsanitary conditions. The literature suggests that the problems associated with the sorting of recyclable waste are associated with lack of structure, contact with the "garbage", lack of government support, lack of training, lack of safety equipment, among others. The scope of this paper is to describe the process of sorting recyclable waste in a cooperative in França in the state of São Paulo. The specific objective was to identify the variables inherent to the process and investigate how workers adjust their work schedules to deal with these variables. The research method used is the case study with an operationalized ergonomic approach at some stages of the ergonomic analysis of work. Exploratory visits, indirect observations and semi-structured interviews were conducted. The results showed that the variables inherent to the process require that workers perform timely management sessions, which can be either collective or individual, though this invariably results in overload in the workplace, either by speeding up the work output or by demanding the increased concentration of those involved.

A triagem de materiais recicláveis e as variabilidades inerentes ao processo: estudo de caso em uma cooperativa / The sorting of recyclable waste and the variables inherent to the process: a case study in a cooperative

O trabalho informal com materiais recicláveis é marcado por desvalorização e exclusão social, além desta atividade ser realizada em condições insalubres. A literatura aponta que os problemas associados à triagem de materiais recicláveis estão relacionados à falta de estrutura, ao contato com o "lixo", à falta de apoio do poder público, à falta de treinamentos, à falta equipamentos de segurança, entre outros. O objetivo geral deste artigo foi descrever o processo de triagem de materiais recicláveis na cooperativa de Franca, SP. O objetivo especifico foi identificar as variabilidades inerentes ao processo e investigar como o trabalhador molda seu trabalho para dar conta destas variabilidades. O método de pesquisa é o estudo de caso com abordagem ergonômica operacionalizada por algumas etapas da análise ergonômica do trabalho. Foram feitas visitas exploratórias, observações indiretas e entrevistas semiestruturadas. Os resultados demonstraram que as variabilidades inerentes ao processo solicitam dos cooperados uma gestão momentânea que pode ser realizada de forma coletiva ou individual, mas que quase sempre causa sobrecarga no trabalho, seja acelerando-o ou aumentando a concentração.

Ergonomics in designing process: dialogue between designers, executors and users in the maintenance activity of radars in an oil refinery.

This paper aims to discuss the role of ergonomics in design process using the dialogue developed by designers, implementers and users in an oil refinery. It was possible to identify the need of minimizing the postural constraints, risk of accidents, mechanical shocks and to enlarge safety perception in the access and permanency of the users at the workspace. It has been determined and validated by workers and managers to implement different deadlines depending on programming, viability and execution time for the improvements proposed. In a long-term: it was proposed the substitution of the ladders with time planning according to the maintenance program of the tanks; in a short-time: it was suggested the expansion of the existing platforms, implementation of a walkway connection provided with guardrails between the upper access of the side ladder and the repositioning of radar set and aerial aiming at the usage by workers at the workstation of the new platform. It was also elaborated eight typologies of intervention, according to the request, type of tank, material stored, and its setting place. The design process arises from ergonomics workplace analysis that presents concepts for solutions which was a mediator tool to be settled between users and implementers.
