Veículo de tração mista a partir da aplicação da metodologia de tecnologia social em organização de catadores de materiais recicláveis

Abstract

The collectors of recyclable materials, essential to the effective management solid waste management, often perform daily activities in unhealthy conditions and without equipment to enhance the work of picking. The development and availability of social technologies, for this audience, are tools to change this reality. Thus, the present work had as main objective to evaluate the pplicability of the methodology proposed in the literature, for the development of a social technology, focusing on ergonomics, in an association of recyclable material collectors. The exploratory, participatory and experimental research was carried out from March 2016 to April 2019, with fourteen recyclable material collectors associated with ARENSA. In the first moment, a survey of the current technologies used by the study group was carried out, simultaneously with the ergonomic analysis of the work. Subsequently, social technology was planned and executed for the collection and transportation of recyclable materials with a focus on ergonomics, a mixed traction cart (human and electric). The methodology proposed by the literature for the production of a social technology has not proved to be totally effective, making it necessary to have an interdisciplinary team in the elaboration, execution and evaluation of the project and in order to avoid costs with prototypes, the use of data is recommended in virtual simulation software in three dimensions (3D), minimizing production costs and greater similarity to what the target audience wants. With this virtualization, there is a reduction in rework, in order to improve the stages of the project under construction. The developed prototype presented as positive aspects: Absence of the need for squats, weight lifting and trunk rotation; presence of two types of brakes; greater volumetric capacity, climate protection; Presence of electric motor, Open handles, with design and adjustment for height and opening; Megaphone; rear-view mirrors, reflective strips, greater visibility before society. Therefore, it is essential to invest in social technologies aimed at the professional practice of recyclable material collectors, in order to enable the implementation of the National Policy for Integrated Solid Waste Management and the socioeconomic insertion of these workers.
