Análise do manejo e de alternativa para destinação final do óleo lubrificante usado ou contaminado (OLUC) no município de Itacoatiara-AM

Abstract

This study aimed to analyze the management and alternative for the final destination of used or contaminated lubricating oil (UCLO) in the municipality of Itacoatiara-AM. For this, a survey was initially carried out on the number of existing mechanical workshops in the central region of the municipality, after which a qualitative and quantitative form was applied. In addition, an experiment was carried out to analyze the use of UCLO in replacement of a termitecide as an alternative form of preservative treatment for wood. For this, the samples were conditioned in the oven in order to remove their moisture. Afterwards, treatments were applied to the test specimens with UCLO, termitecide and control, and were exposed to the attack of termites. Each stage lasted three weeks, totaling three stages and nine weeks. To determine the efficiency of the treatments, two weights were used to calculate retention rate and mass loss. In the central region, nine workshops were found, one small and eight medium-sized. One of the workshops reached an UCLO generation value of 3000 liters per month. It was identified that the main destination of UCLO is its receipt, where the value of the liter was R$ 3,00. In the second part of the study, it is taken care that UCLO has a greater retention in the sample compared to the termiticide. Both UCLO and the termiticide had the same efficiency, since all Experiments were not tried, unlike the controls that had mass loss in all their Demonstrations. Therefore, it is concluded that all UCLO residue generated in the central region does not have a correct destination, which can generate several impacts, an alternative would be the use of UCLO as preserved in wood of any type, in order to increase its durability and against xylophagous attacks.
