Rapid population growth and urbanization have led to an increase in Construction and Demolition (C&D) waste, prompting government and industry bodies to develop better waste management practices. Waste trading has emerged as a targeted intervention to divert waste from landfill sites and create a second life for waste material. This paper examines key barriers and enablers influencing the creation of a marketplace for waste trading. A systematic literature review was undertaken to examine global efforts in creating a marketplace for C&D waste. A framework on enablers and barriers for developing a marketplace for C&D waste emerged from the review, based on market-based, operational, and governance factors. References demonstrated that markets for materials such as glass and metals have already been established, but there are increasing marketplace opportunities for other recycled materials. Technology-based market applications are emerging as targeted interventions to facilitate online trading, which will provide a more accessible and user-friendly marketplace for sellers and buyers. Further research should test the complex interactions between people and technology associated with online waste trading platforms, as well as help develop the business case for a C&D waste marketplace.

Construction and demolition waste are the major issue as a direct consequence of increased global urbanization. It impacts the environmental efficiency of the construction industry, contributing to 35% of the global landfill. This research considers the two main fundamental factors affecting the demolished building waste management, which are the management hierarchy including the 3R strategies and the project life cycle and management tools. The inappropriate treatment and disposal of Construction and demolition waste give rise to the environmental pollution, land price, and natural resource consumption. This paper scrutinizes the concept of Construction and demolition waste management and review the extant studies in the managerial areas of Construction and demolition waste. These findings are aimed at clarifying the current and future practices of Construction and demolition waste management practices with an understanding for the sustainable governance. Keywords: Construction and demolition waste, management, review.

Three Dimensional Virtual Worlds (3DVW) have been substantially adopted in educational and pedagogical fields worldwide. The current study conducted a systematic literature review of the published research relevant to the application of 3DVWs in higher education. A literature search was performed in eight high-ranking databases, and following scrutiny according to inclusion criteria, 164 papers were selected for review. The systematic literature review process was summarized, reviews undertaken by the authors, and results about the applicability of 3DVWs in higher education were extracted. A wide variety of application areas for the 3DVWs in higher education were found, and were classified into five main categories. Various 3DVW platforms and virtual environments used for educational goals were also identified. The results revealed Second Life as the most popular 3DVW platform in higher education. This study also found that by using 3DVW technology a wide range of virtual environments and virtual tools have been designed and applied in teaching and learning for higher education.

PurposeThe aim of this paper is to present the main findings of the studies in the field of quality management (QM) in primary and secondary education. Grouping these findings into themes and these themes, in turn, into broad categories as well as prioritizing the themes of findings are also aims of the present study.Design/methodology/approachA systematic literature review (SLR) of articles focusing on QM in primary and secondary education was carried out based on major publishers, namely Emerald Online, Taylor and Francis, Elsevier/Science Direct, Springer Link, Sage Publishing and Online. In total, 133 articles published in 62 journals during 1983–2019 were collected. The affinity diagram was applied in order to group the findings of the QM studies into logical themes and these themes into broad categories. Moreover, the Pareto diagram was applied to prioritize the themes revealed.FindingsA plethora of articles focusing on QM in primary and secondary education have been published in the last decades. The findings of the QM studies presented in the 133 reviewed articles are grouped into 43 themes and these themes, in turn, into 6 broad categories, namely management practices, school characteristics, teachers, stakeholders, government and pupils. The analysis also reveals themes that can be characterized as “vital” and “useful.”Practical implicationsResearchers and school managers can take into consideration the findings of the QM studies in primary and secondary education as well as the themes of high priority for the design of future studies and QM implementation plans, respectively.Originality/valueThis is the first literature review study which presents analytically the findings of the QM studies in primary and secondary education. This study also contributes to the literature by formulating meaningful themes of these findings and broad categories of these themes and by prioritizing the themes revealed.

Construction and demolition waste (CDW) accounts for at least 30% of the total solid waste produced around the world. At around 924 million tons in the European Union in 2016 and 2.36 billion tons in China in 2018, the amount is expected to increase over the next few years. Dumping these wastes in sanitary landfills has always been the traditional approach to waste management but this will not be feasible in the years to come. To significantly reduce or eliminate the amount of CDW being dumped, circular economy is a possible solution to the increasing amounts of CDW. Circular economy is an economic system based on business models which replaces the end-of-life concept with reducing, reusing, recycling, and recovering materials. This paper discusses circular economy (CE) frameworks—specifically material recovery and production highlighting the reuse and recycling of CDW and reprocessing into new construction applications. Likewise, a literature review into recent studies of reuse and recycling of CDW and its feasibility is also discussed to possibly prove the effectivity of CE in reducing CDW. Findings such as effectivity of recycling CDW into new construction applications and its limitations in effective usage are discussed and research gaps such as reuse of construction materials are also undertaken. CE and recycling were also found to be emerging topics. Observed trends in published articles as well as the use of latent Dirichlet allocation in creating topic models have shown a rising awareness and increasing research in CE which focuses on recycling and reusing CDW.
