“…The data show that their use is still very inefficient, given the high amount of waste generated disposed of in landfills and not recovered as also in the case of C&DW and WEEE. CE proposes to rethink and reverse the pattern of the linear model of consumption of natural resources by means of different solutions for improving production and consumption efficiency and having as central the concept of waste elimination by design, design for disassembly, repair/reuse/recycling/refurbishment (Oluleye et al, 2022). We have underlined that framing the concept of urban mining in the CE practical model is a central message that this study would like to convey as it is relevant for the optimization of the whole urban mining process and prolong the use of virgin materials for achieving more sustainable patterns in their consumption.…”

“…Good practices beyond recycling can also be found for C&DW across Europe and at the global level (Legambiente, 2016(Legambiente, , 2017Ramakrishna et al, 2021;Oluleye et al, 2022). Several building projects show that, by means of the creation of a synergy between circular design and production, it is possible to design buildings that are easily disassembled at the end of life, and their C&D materials can be reused again for new buildings .…”

“…The concept of "urban mining" is the key in the CE model and the parallelism with the traditional mining activities help in understanding why it is so important. Let us remember that the concept of CE emerged in response to the need for reducing the demand of finite natural resources and better use them in the whole life cycle of products, components, and materials (Ghisellini et al, 2016;Geissdoerfer et al, 2017;Kirchherr et al, 2017;Panchal et al, 2021;Oluleye et al, 2022). It is suggested that, under a CE, the global society would live on Earth within the means of its energy and material resources (Deutz, 2020) being conceived as a closed system (Boulding, 1966).…”

This study evaluates the perspectives of urban mining in the framework of the circular economy (CE) and starts with a brief analysis of the size of global and urban metabolism and the role that plays materials and waste streams such as construction and demolition waste (C&DW) and waste from electronic and electrical equipment (WEEE). These can be considered as temporary stocks or deposits to be mined in the future, thus shedding light on the concept of recycling potential, end-of-life functional recycling, and material concentration. The recycling potential could be very variable as in the case of metals. The average concentration of some metals (e.g., gold) in WEEE shows that it is higher per ton of electronic product compared to the amount in mining ores. This explains the importance of the concept of urban mining in the circular economy (CE) transition, given that the CE concept was born to address the challenges of high resources consumption rates and worsening environmental problems. The urban mining phenomenon becomes timely and extremely important for cities as they are relevant hubs of materials and energy consumption and source of environmental and social impacts in external areas due to mining and extraction activities. This study points to the need for creating and establishing strong synergies between the concept of CE and urban mining and the role of cities as innovators in finding circular solutions by incorporating more socially just urban mining activities to improve urban resource management, land use, and local and global wellbeing.

“…Further, the collected data is conducted through bibliometrics and visualization VOSViewer (Van Eck & Waltman, 2018), aimed to observe future research trend and agenda. Reviews of current and future research have been carried out using bibliometric studies, such as those carried out to find out powertrain technologies (Conway et al, 2021), logistics Internet-of-Things (Abdul et al, 2021), remediation of microplastics using constructed wetlands (Xu et al, 2022), Constructed wetlands in 1991-2011 (Zhi & Ji, 2012), sous vide processing in the meat industry (Thathsarani et al, 2022), and circular economy research on building construction and demolition waste (Oluleye et al, 2022).…”

Digital economy serves as one of the agenda of Association of Southeast Asian Nations (ASEAN) in undertaking the Fourth Industrial Revolution. Additionally, the Indonesian government is committed to conducting research and innovation related to digital economy. Therefore, this study aims to reveal trends and future research under the topic of digital economy in Indonesia. This study utilizes big data methods, conducted through Scopus database, while the analysis is conducted through bibliometrics and visualization VOSViewer. The results of this study indicate that financial technology becomes the most published topic by authors with affiliation from Indonesia, although the topic has been widely discussed in international journals. Meanwhile, future research topics include research on digital payments, technology acceptance for the Micro, small, and medium enterprises (MSMEs), digital transformation for e-learning, and e-government.

The main relevant difference between recycled concrete aggregates (RCAs) in comparison with the companion natural ones, is the presence of the Attached Mortar content which confers to the RCAs higher porosity and, consequently, higher water absorption capacity. In the last decades, several studies have been performed worldwide for unveiling the role of the employed RCAs on the resulting concrete mixture performances at both fresh and hardened states. On the other hand, the effects of RCA on the early‐age and/or long‐term concrete deformations (e.g., shrinkage) are still very limited. In this context, this article summarizes the results of a wide experimental campaign aimed at evaluating the influence of RCAs on the autogenous and drying shrinkage of normal (35 MPa) and high (60 MPa) strength recycled aggregate concrete (RAC) mixtures. A total of 10 mixtures were realized by considering the variation of both the original source and size of employed RCAs. The results showed a clear correlation between the intrinsic properties (i.e., Attached Mortar content) of the employed RCAs and the resulting concrete deformation. Moreover, although the drying shrinkage is higher for RAC mixtures, the presence of a more porous aggregates mitigates the observed autogenous shrinkage. Consequently, the overall total shrinkage result to be almost unaffected by the presence of the recycled particles.
