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：建筑业在多数生产场景中会产生大量废弃物，由于未得到合理的末端处置，这些废弃物最终会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号决议及其后续修订案，制定了民用建筑废弃物的规范化管理导则。在此背景下，本文通过定量研究，旨在探明圣保罗州（São Paulo）里贝朗普雷图市的民用建筑废弃物（本文简称RCD）治理现状；研究以183.28 kg/m²的废弃物产生率为基准，通过许可施工面积与合规处置点位的清运量两个参数，核算该市的建筑废弃物产生总量，分别得到1112.35吨/日与561.98吨/日的核算结果。本研究进一步对上述数值开展关联性分析，得到该市人均建筑废弃物产生量为1.24 kg/(人·日)。综上，本文探明并量化了圣保罗州里贝朗普雷图市的建筑废弃物产生情况，可为后续与现有研究文献的对比分析提供数据支撑与参考依据。
