Study of the rate of generation of waste from construction in new works in the city of Ribeirao Preto-SP

Abstract: In the construction industry, many waste products are produced most part of the time, because they do not have a correct end, end up causing strong impacts on the environment. To this end, CONAMA Resolution No. 307/2002 and its amendments thereafter determine the guidelines for the management of civil construction waste appropriately. In this context, this article aims, through a quantitative study, to identify the situation of civil construction waste, called here as RCD, in the city of Ribeirao Preto, determining the amount of waste generated through two parameters; licensed areas and volume disposed of at authorized locations, from a generation rate of 183.28 kg/m2, generating 1,112.35 t/day and 561.98 t/day respectively. The work sought to relate the values and obtained a per person generation of 1.24 kg/inhab × day. Thus, the article identified and measured the generation of construction waste in the city of Ribeirao Preto-SP, providing subsidies and information for comparisons with existing bibliography.

摘要：建筑业在多数作业场景下会产生大量废弃物，由于缺乏合理的末端处置方案，最终对环境造成严重负面影响。为此，巴西国家环境委员会（CONAMA）第307/2002号决议及其后续修正案，明确了民用建筑废弃物的规范化管理指南。在此背景下，本文通过定量研究，对圣保罗州里贝朗普雷图市的民用建筑废弃物（RCD）处置现状展开调研：基于183.28 kg/m²的产生率，以合规作业区域规模与授权处置点位处置量为两项参数，分别测算得到日均产生量1112.35吨与561.98吨。本研究对上述数值进行关联分析，最终得到该市人均建筑废弃物产生量为1.24 kg/人·日。综上，本文完成了圣保罗州里贝朗普雷图市建筑废弃物产生量的识别与测算，可为后续与现有文献的对比研究提供支撑依据与参考信息。
