Diagnóstico da geração de resíduos da construção civil (RCC) no município de Medianeira/PR e proposta de implantação de uma unidade de gerenciamento e valorização

Abstract

The construction sector plays a crucial role in economic and social development, but it also generates significant environmental impacts due to its significant generation of waste and the way in which it is disposed of. With this in mind, the National Environmental Council (CONAMA) approved Resolution No. 307 in 2002, which establishes guidelines for the management of construction waste (RCC). This study aimed to estimate the amount of RCC generated in the municipality of Medianeira/PR, using data from construction licenses issued between 2016 and 2022. It was estimated that during this period approximately 99,822.89 tons or 83,186 m³ of RCC were generated for new works, with around 90 thousand tons equivalent to 75 thousand m³ of RCC Class A. An increase of around 80% in the number of RCC buckets per day was observed during these years. With an estimated population of 54,369 inhabitants in 2022, the average amount of RCC per inhabitant was 377.75 kg per year. The analyzes showed that the growth of built areas in the municipality follows a linear trend, with projections indicating an increase of approximately 50% in the built area by 2033, reaching 203,492 m². To better manage and value this waste, a plot of land measuring 261,750.00 m² was selected to implement an RCC management unit. This complex will include structures such as fencing, plant barriers, guardhouse, road scale, administrative headquarters, public and equipment parking, transshipment and sorting area, as well as specific locations for storing different classes of RCC, crushing and temporary storage of processed waste from the Class A.
