Construction and demolition waste management in developing countries: a diagnosis from 265 construction sites in the Lima Metropolitan Area

Abstract

The construction industry is a driver of economic and social development in developing countries; however, it is also one of the primary sources of entropic elements such as construction and demolition waste (CDW). Since construction is expected to continue growing, it is essential to study the CDW status under these scenarios. To the best of the author's knowledge, this is the first academic research in Peru that deals with CDW. The information for the research is collected from primary and secondary sources, which includes 265 surveys, interviews, and visits to construction and disposal sites. The results are obtained from a cross-analysis of the influence of different aspects (experience and education level of the construction site manager, dimension, or socio-economical level of the site, building use, among others) on CDW management. Further, significant findings related to each stage of the CDW cycle are presented. The obtained findings provide information for effective decision making in terms of policies and regulations on CDW, which will help improve its management, reduce environmental impact, and provide economic benefits, especially in developing countries.

Circular Economy, International Cooperation, and Solid Waste Management: A Development Project in La Paz (Bolivia)

“…The CDW management system implemented at the municipal level is totally informal. Before 2021, no formal collection and treatment systems were available in Bolivia, as is common in developing countries [23,24]. The amount of CDW generated in La Paz is estimated by secondary data.…”

Mapeamento de Pontos de Deposição Irregulares de Resíduos de Construção e Demolição da Cidade de Caruaru, Pernambuco

“…É necessária uma estimativa precisa dos quantitativos de geração dos RCD que ajudam a analisar sistematicamente as ineficiências dos processos e garantem que medidas de redução específicas sejam desenvolvidas (Xu et al, 2019). Estes resíduos podem se tornar potenciais geradores de bem-estar econômico e social e não um poluidor ambiental (Rondinel-Oviedo, 2021). A compreensão da dinâmica da geração de RCC é essencial para um plano de gestão com medidas de redução dos impactos à população que deve garantir ações na coleta, manuseio e destinação final (Yu et al, 2019;Bakchan e Faust, 2019).…”

Sustainability assessment of Construction and Demolition Waste management applied to an Italian case

“…Likewise, the results provided by Borghi et al (2018) demonstrate the environmental advantages of landfill avoidance, but the economic and social perspectives are left behind. Jain et al (2020) showcase that integrated wet recycling is environmentally sound alternative compared to landfilling in most of the cases, while Rondinel-Oviedo (2021) , after performing some surveys and interviews to the main stakeholders, underline the importance to provide incentives for selective demolition.…”
