Resumo

O setor da construção tem se tornado um dos grandes motivos de preocupação ambiental, principalmente quando se trata da emissão de dióxido de carbono e geração de resíduos. Uma forma de mitigar tais impactos consiste na substituição de um sistema linear para um modelo de Economia Circular (EC). Nesse modelo, a reciclagem de Resíduos de Construção e Demolição (RCD) consiste em uma prática bastante estudada há mais de 20 anos, enquanto pesquisas sobre o reuso de elementos construtivos a partir da metodologia de projetar para desconstrução (DfD, Design for Deconstruction/Disassembly) tem ganhado destaque apenas nos últimos cinco anos. Dentre tais pesquisas, a avaliação da sustentabilidade por meio de indicadores ambientais é ainda mais escassa. Desta forma, o presente artigo faz uma revisão sistemática da literatura, reunindo trabalhos que apontam os principais avanços da prática DfD, com foco em estruturas de concreto armado sob a perspectiva da Avaliação do Ciclo de Vida (ACV). Com base nos artigos analisados, foi observado que, apesar da ausência de método unificado para quantificar seus benefícios, a prática de DfD se mostrou vantajosa para atenuar os impactos ambientais do setor da construção.
