Levantamento dos índices dos resíduos gerados em obras de uma construtora em Londrina-PR e Maringá-PR

Abstract

The civil construction sector undergoes constant changes over time, seeking improvements in construction methods in order to generate less and less waste in construction sites, minimizing impacts on the environment. The Civil Construction Waste Management Plan (PGRCC) is an important tool in this process, as it is possible to estimate the volume of waste that will be generated on the construction site, in order to manage and minimize the waste of materials in the construction of the project. Therefore, the rate of generation of construction waste must be in accordance with reality in order to have an accurate quantification of waste in the PGRCC. Thus, this work aims to obtain these indexes, in addition to establishing a comparative view between the volumes produced for each class of RCCs in two situations: including and excluding the volume of soil generated. For the generation of indexes and percentages, PGRCCs of 13 works were used, 5 in the city of Maringá-PR and 8 in the city of Londrina-PR, provided by the partner construction company. The enterprises in Londrina showed Average Indexes higher than those presented in the city of Maringá. When taking into account the volume of soil generated in the construction of the project, the difference in the Average Index was 0.32431 m³.m ², while when excluding soil waste, the difference was 0.03564 m³.m ². This difference shows that due to the variability it is better to compose the Index excluding the soil. The percentages of class A waste in both cities were above 64% when soil was included and above 54% without this waste.
