“…Figure 12 also highlights that 40% CDW is the optimal content in the soil, though the trend of the plots didn't flatten yet because CDW contain clay-sized cement and sand. The percentage of CDW in the current research is marginally higher than some previous researches because of the type and particles size of CDW and soil ( Jayatheja et al., 2017 , 2021 ; Suluguru et al., 2018 , 2019 ). Figure 12 Cohesion and angle of internal friction of soil-CDW mixtures.…”

“…Construction and demolition waste (CDW) is produced during the construction of any civil engineering structure or demolition project. Concrete, plaster, metal, wood, plastics, and other complex and non-biodegradable substances make up the most of it ( Poon et al., 2001 ; Jayatheja et al., 2021a ). Construction and demolition waste are diverse and influenced by the country's socio-economic status and local engineering practices ( Asprone et al., 2015 ).…”

Having in mind the objectives of the United Nations Development Agenda 2030, which refers to the sustainable principles of a circular economy, it is urgent to improve the performance of the built environment. The existing buildings must be preserved and improved in order to reduce their environmental impact, in line with the need to revert climate change and reduce the occurrence of natural disasters. This work had as its main goal to identify and define a methodology for promoting the rehabilitation of buildings in the Ponte Gêa neighborhood, in the city of Beira, Mozambique, with an emphasis on energy efficiency, water efficiency, and construction and demolition waste management. The proposed methodology aims to create a decision support method for creating strategic measures to be implemented by considering the three specific domains—energy, water, and waste. This model allows for analyzing the expected improvement according to the action to be performed, exploring both individual and community solutions. It encompasses systems of standard supply that can reveal greater efficiency and profitability. Thus, the in-depth knowledge of the characteristics of urban space and buildings allows for establishing guidelines for the renovation process of the neighborhood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
