Análise da geração de resíduos sólidos, consumo de água e energia elétrica no canteiro de obras: um estudo de caso na cidade de Campo Mourão - PR

Abstract

The civil construction sector has shown technological advances in recent years, but the environmental aspects associated with the activity of civil construction are also highlighted, due to the considerable amount of environmental resources used, as well as the amount of solid waste generated. Studies that bring data referring to the environmental performance of projects tend to corroborate so that better environmental management practices are adopted. In this context, the present study aimed to analyze the generation of solid waste, the consumption of water and electricity in a commercial residential project, in the infrastructure and suprastructure phase, in the city of Campo Mourão, Paraná. Records of destination of construction waste (RCC) and invoices for water and electricity consumption from the concessionaires were used to collect and analyze the data, both made available by the construction company responsible for the work. It was found that, in the period analyzed, from 2017 to 2020, 238.6 m³ of RCC were generated, which corresponds to approximately 0.063 m³ per constructed m². When specifically analyzing the quantity of RCC Class A, the generation indicator is approximately 0.037 m³ per constructed m². The total water consumption was 497 m³, which corresponds to approximately 0.131 m³ per m² built, and the total electricity consumption was 9561 kWh, around 2.52 kWh per m² built.
