“…LCA methodology is often used for the environmental assessment and comparison of aggregate (natural and recycled aggregate) and concrete (ordinary concrete and recycled aggregate concrete). Many comparative studies using this methodology have been published [4,8,13,16,20,23,24,60,[73][74][75][76][77][78][79][80][81][82][83][84][85][86].…”

The main goal of this study was to compare two use cycles of natural aggregate concrete and recycled aggregate concrete, which is another way to compare the environmental impacts of recycled materials. A series of concrete mixtures with various replacement ratios of primary resources with recycled ones were prepared for this study. The mechanical properties of concrete mixtures were examined and were used for the design of structural elements in the same utilized properties. The two use cycles of a structural element were compared using life cycle assessment (LCA). In the first use cycle, the LCA of the structural element containing only primary raw materials was assessed. In the second use cycle, the LCA of a structural element in which primary materials were partially replaced by recycled ones was assessed. The obtained results confirm the potential use of high-quality recycled aggregate originating from local sources in some applications in building structures. Furthermore, the environmental assessment indicates the benefits of using recycled materials, such as environmental savings, especially the reduction of primary resource use, embodied energy, and embodied emissions, as well as reduction of the pressure on landfill sites.

“…In other words, the results of the content analysis indicated that the current focus of reverse logistics literature in the construction industry is primarily on end-of-life waste management.

A Review of Reverse Logistics: An Upstream Construction Supply Chain Perspective

2019

Construction industry activities, from material extraction to the end of the structure life, affect the environment negatively. For a sustainable construction process, economically, environmentally, and socially friendly practices are essential, and reverse logistics is one solution that can provide such an approach. In reverse logistics, obsolete products are reused in a new production, while reducing negative effects to the environment. In this study, we assess the current state of research on reverse logistics practices in the construction industry. The study presents a comparative data mining analysis, followed by a content analysis. The results show that the construction industry literature ignores the impact of reverse logistics practices on upstream construction activities. We argue that industry practitioners must take reverse logistics decisions in the early phases of the construction process by considering both upstream and end-of-life construction activities, and we recommend a reverse logistics decision framework for successful reverse logistics implementation. The findings of this research are significant for decision-makers in the industry. We urge that sustainable practices be employed in the industry. Furthermore, a quantitative analysis is suggested to strengthen the arguments made in this article.
