“…Moreover, construction waste can be recycled or reused as building materials through integrated waste management systems that include waste sorting, reducing illegal dumping behaviour, promoting the government's nancial subsidy on waste recycling, and increasing waste land lling charges, which is an opportunity for extracting economic and environmental bene ts from waste as reductions in CO 2 emissions, energy use, natural resources and illegal land lls (Islam, 2019, Hao et al, 2019).…”

Background: Currently, most of the world’s population lives in cities, and this trend of the rapid urbanization of the population affects the increase in the demand for products, goods and services. To effectively design policies for urban sustainability it is important to know the trends of the flows of energy and materials that enter and leave the city. This knowledge is essential to recognize key elements characterizing the future urban growth and to be able to face supply challenges in the future. This paper presents the analysis of the flows of energy and materials (urban metabolism) in the city of Bogotá, covering a time span from 2001 to 2017. Urban flows are also characterized in terms of their temporal evolution with respect to the population growth, in order to compare and identify the changes in the main input flows, wealth production, emissions and waste in the city.Results: The results of the analysis are also compared with other selected large urban agglomerations in Latin America and worldwide, highlighting similarities and inferences. The results show that in Bogotá, there was a decrease in some of the material flow in recent years, such as the consumption of water and the generation of discharge, while there was an increase in the consumption of energy and cement and the production of CO2 emissions and construction materials. Solid waste production remained relatively stable. With respect to the other large cities considered, we observe that the 10-year growth rates of the metabolic flows with respect to the population growth are lower, in particular when compared with the other urban agglomeration of Latin America.Conclusions: The findings of this study are important to advance the characterization of the trends in material and energy flow in the city and contribute to the consolidation of a baseline that allows for the definition and evaluation of the different impacts of public policy that promotes the sustainability of the city in the coming decades.

“…e construction industry consumes more raw materials than other social activities, leading to the depletion of natural resources and the production of construction waste [1,2]. It is suggested that one of the most effective ways to reduce building resource consumption and achieve sustainable building practices is to use recycled materials made from waste and renewable materials [3][4][5]. Among sustainable materials, ecological composite materials are increasingly concentrated because of their advantages, such as reuse of waste, low overall impacts on the environment, and biodegradability and nontoxicity [6,7].…”

In the construction industry, an approach to alleviate the environmental problem is to apply ecological composite materials to the construction field. In this paper, the authors added the recycled aggregate and the rice husks to the concrete and measured the strengths of rich husk recycled concrete (RHRC) with different factors as well as determined the constitutive model. Subsequently, the flexural experiment of RHRC sandwich wall was carried out and analyzed in detail, which proved that it could bear the wind loads in normal use condition by the calculation of the experimental data. Then, the compressive experiment and analyses were conducted similarly. Moreover, the finite element method was applied to study the influence of tie bars on the flexural bearing capacity and to deduce the simplified calculation method of vertical bearing capacity of RHRC walls.

“…According to some estimates, India generated about 0.53 billion tonnes of C&D waste in 2013, thus making it the second largest generator of C&D waste in the world (Akhtar and Sarmah, 2018; Manuja et al, 2016). C&D waste contributes about 30–50% of the total solid waste generated worldwide (Akhtar and Sarmah, 2018; Galvez-Martos et al, 2018; Hoornweg and Bhada-Tata, 2012; Islam et al, 2019; Manuja et al, 2016; Tam and Lu, 2016). The provision of housing and associated infrastructure plays an important role in countries undergoing rapid development and urbanization.…”

The growth of the Indian construction sector is expected to result in a significant demand–supply gap with respect to construction materials such as sand, limestone, and aggregates. Additionally, the vast quantity of unprocessed Construction and Demolition (C&D) waste pose serious problems in some places, particularly in residential, institutional, industrial or commercial construction hotspots. While several waste quantification methodologies have been proposed in the literature, the quantification of waste generation in India is inadequate. This inadequacy can be attributed to the lack of appropriate hierarchical control mechanism, absence of a common C&D waste estimation method, and the lack of C&D waste processing knowledge among generators, collectors, operators, regulators, and the general public. The C&D Waste Management Rules 2016 were introduced to ensure organized collection, storage, transportation, treatment/processing, and disposal of C&D waste in India and fix responsibilities of all stakeholders for management of C&D waste. This comprehensive research attempts to analyze the existing legislation and challenges, and proposes an information framework for organized collection, storage, treatment/processing, and disposal of C&D waste. The C&D waste processing mechanism, potential application of recycled C&D waste products, its limitations, and the best practices of C&D waste management in India are important constituents of the proposed framework.
