Abstract(s)
Este projeto tem como objetivo analisar a gestão de Resíduos de Construção e Demolição (RCD) no setor de Construção Civil e o possível impacto económico que essa gestão poderá ter nesse setor. Neste sentido, foi efetuado um estudo de caso com base na informação disponibilizada por uma determinada empresa.
O principal objetivo do estudo de caso, foi analisar a produção e a gestão de RCD, com o intuito de verificar se a gestão de RCD poderá influenciar os custos associados à produção e encaminhamento dos mesmos, nos estaleiros de obras.
A empresa analisada neste estudo de caso, possui diferentes estaleiros de obras em várias regiões de Portugal, tendo sido estudado o nível de produção de resíduos, assim como os custos envolvidos em todo o processo, entre o período que decorreu entre 2016 e 2021.
Os resultados obtidos das análises efetuadas indicam que ainda existem várias barreiras (sociais, ambientais e económicas), referenciadas também na literatura, que originam falhas na gestão de RCD. Este estudo de caso sugere que uma correta gestão de RCD, mais concretamente uma melhoria na triagem dos resíduos produzidos, poderá afetar os custos associados levando à sua diminuição.
As conclusões apuradas levaram à sugestão de melhorias em futuros estudos, tais como: a elaborarão de uma análise a um conjunto maior de empresas e uma caracterização mais aprofundada sobre os estaleiros de obras, (ex.: área de implantação; tipos de materiais utilizados) na tentativa de antecipar a quantidade de RCD produzidos em futuras obras, assim como os custos associados apoiando os produtores de resíduos na tomada de decisões importantes sobre a gestão de RCD.
This project aims to analyze the management of Construction and Demolition Waste (CDW) in the Civil Construction sector and the economic impact that this management may have in this sector. This way, information from the case study company was provided based on certain information. The main objective of the case study was to analyze the production and management of CDW, in order to verify if the management of CDW can influence the costs associated with their production and forwarding at the construction sites. The company analyzed in this case study, has different construction sites in various regions of Portugal. This work aims to study the level of waste production, as well as the costs involved in the whole process, from 2016 to 2021. The results obtained from the analysis carried out, indicate that there are still several barriers (social, environmental and economic), as also referenced in the literature, which contribute to failures in the management of CDW. This case study suggests that a correct management of CDW, more specifically an improvement in the sorting of waste produced, may affect the associated costs leading to their reduction. For further improvements, there are following suggestion for future studies, such as: the elaboration of an analysis of a larger group of companies and a more in-depth characterization of the construction sites (ex.: implantation area; types of materials used). So it allows to anticipate the amount of CDW produced in future works, as well as the associated costs, supporting waste producers in making important decisions about CDW management.
