“…To date, more than a hundred billion tons of CDW were generated in the world, while approximately 30% to 50% of them were waste concrete [2]. However, this considerable amount of waste concrete is mainly disposed of in landfills, resulting in a severe environmental problem [3][4][5][6]. In order to protect the ecological environment and achieve sustainable development, reducing, reusing, and recycling construction waste is a desirable approach to preserve the ecological environment [7][8][9][10][11].…”

Experimental Study on the Seismic Performance of Recycled Concrete Hollow Block Masonry Walls

et al. 2019

This paper aims to manufacture recycled concrete hollow block (RCHB) which can be used for the masonry structure with seismic requirements. Five RCHB masonry walls were tested under cyclic loading to evaluate the effect of the axial compression stress, aspect ratio, and the materials of structural columns on the seismic performance. Based on the test results, the failure pattern, hysteresis curves, lateral drift, ductility, stiffness degradation, and the energy dissipation of the specimens were analyzed in detail. The results showed that with the increase of aspect ratios, the ductility of RCHB masonry walls increased, but the horizontal bearing capacity and energy dissipation of RCHB masonry walls decreased. With the increase of compressive stress, the bearing capacity and energy dissipation performance of RCHB masonry walls were improved, and the stiffness degraded slowly. The results also demonstrated that the RCHB masonry walls with structural columns, depending on whether the structural columns were prepared by ordinary concrete or recycled concrete, could increase the bearing capacity, ductility, and energy dissipation of specimens. The research confirmed that RCHB masonry walls could meet the seismic requirements through thoughtful design. Therefore, this study provided a new cleaner production for the utilization of construction waste resources.

“…One of the material’s flow-paths refers to unrecoverable CDW. Fu et al (2017) and Xu et al (2018) verified that after the separation process, irredeemable CDW may transpire due to waste contamination and/or lack of recycling technology.…”

“…The actual size and complexity of a facility depends upon available regional technology and the quality of sorting processes, as performed on the previous node ( Hiete et al, 2011 ; Wang et al, 2004 ). Similar to the ‘ CDW regional separation centres ’ node, these facilities can be managed by private ‘ waste recovery companies ’ ( Rahimi and Ghezavati, 2018 ; Xu et al, 2018 ) or ‘ government ’ ( Nunes et al, 2009 ) – both have similar goals of planning, executing and controlling the CDW recovery process, in conformity to required quality standards and at the lowest possible cost.…”

“…The final swim lane represents the distribution of products and different kinds of waste, for example, products that can be recycled or remanufactured. Waste distributed can also include unrecoverable CDW, such as heavy metal scrap and some types of plastic ( Fu et al, 2017 ; Xu et al, 2018 ).…”

“…Both ‘ government ’ and ‘ landfill operator ’ actors, when responsible for its operation, share the same objective which is to plan, execute and control the CDW disposal process. Xu et al (2018) state that the recycling ratio of CDW is directly influenced by the disposal fee – this illustrates that government can leverage the volume of CDW recycling to protect the environment through the landfilling fee. This happens because it is cheaper for contractors to dispose of CDW directly to landfills than to implement RL ( Chileshe et al, 2016a ; Hosseini et al, 2014 ; Rameezdeen et al, 2016 ).…”

Reverse supply chain conceptual model for construction and demolition waste

et al. 2021

View full text Add to dashboard Cite

Construction and demolition waste (CDW) substantially contributes to environmental degradation because of its intrinsic characteristics of fast and high generation volume, low recycling rate, and low revenue margins. A systemic problem is that recycling facilities are not usually a part of a reverse supply chain (RSC) specific for CDW. This makes the recovery process costs prohibitive, especially where companies are unable to receive and process large volumes of waste continuously. This paper presents a systematic analysis of the extant literature and utilizes the results accrued to develop a conceptual RSC model for CDW. In so doing, the research seeks to provide clarity on this phenomenon, while simultaneously stimulating wider academic discourse and further research endeavours. A mixed philosophies epistemological design was adopted using both interpretavism and constructivism to undertake a qualitative systematic analysis of the literature. A process diagram was produced to represent the conceptual model (CM) and thematically group the nodes into three key swim lanes that delineate the boundaries between distribution, manufacturing, and sourcing and warehousing processes. Within each swim lane, stakeholders were incorporated as key actors. A further layer of nuanced complexity was added to illustrate the key actors involved in the process, government strategies, and activity flow paths. This novel CM offers both practical and theoretical contributions to existing knowledge and signposts a future research direction. Such work will demystify reverse logistics for managing CDW, and assist government policy-makers to develop informed policies that reduce the negative environmental impact of construction activities.
