Controle da prática de logística reversa na construção civil : um estudo de caso sobre a análise do desempenho operacional na empresa Ciclo Ambiental nos anos de 2014 a 2017

Abstract

This research had as objective to analyze the operational logistic control of the reverse logistics (LR) actions applied in the civil construction sector (CC) by the company Ciclo Ambiental, from 2014 to 2017. As to its typology it was characterized as an exploratory research -descriptive, with quantitative and qualitative approach, through the use of descriptive, inferential and content analysis. The research is a case study applied to Ciclo Ambiental company, pioneer in the management and treatment of CC waste (RCC), located in Camaragibe-PE and with capacity to process 900 tons of RCC / day. Data on the operational control of LR activities were made available in the period from 2014 to 2017, as well as documents, as well as visits were made to the company to verify the operationalization of the RCC treatment, from its receipt to its disposal for sale under the form of recycled aggregates and, finally, the application of a semi-structured interview with the manager Flavio Guimarães. In order to analyze the variables, we used descriptive statistics, Fridman test, as well as the construction of the trends of the percentage of input of the RCC and percentage of output of the recycled aggregates, through the construction of the multiple linear regression model, with the statistical software SPSS. For the analysis of the information obtained in the semi-structured interview, the content analysis technique was used to construct the word cloud using Nvivo Plus software as support. The results showed that, in applying the Fridman test under the percentages of RCC entry and exit of recycled aggregates, there was a significant difference (p <0.05) between 2014 and 2017. Regarding the analysis of multiple linear regression under the operational performance (input of RCC and output of recycled aggregates), it was found that only in the rubble was an average percentage increase of 19.23% of the repre- sentativeness of the rubble compared to the others input materials in the company and was the only RCC in which this trend was highly significant (p-value = 0.010). Based on the information obtained in the semi-structured interview it can be noted that the existence of environmental laws intensifies the adoption of the LR and that the recycled aggregates coming from the CC have an average value 40% lower than the first line products and can be used in pavements. However, there is still a lot of "prejudice" in the use of this aggregate, which makes it difficult to sell on a large scale. Based on the foregoing, it is concluded that for LR to provide sustainable benefits, cost reduction / profit maximization and competitive advantage, it is essential, besides the existence of legal mechanisms that intensify its practice, control policies by the competent bodies to ensure its adoption and compliance, as well as, for management purposes, the presence of control tools, such as the analysis of operational performance, so that through the management of this practice can be monitored, evaluated and rectified when executed.
