Sustainable temporary architecture after a disaster includes temporary buildings designed to meet the emergency housing needs of disaster victims. This approach minimizes the use of waste and natural resources, reduces the environmental impact, and assumes an important responsibility to maintain the long-term ecological balance. Within the scope of this research, comprehensive and systematic results are presented by analyzing disaster issues with the “reuse” strategy, which has started to be frequently encountered in the current literature. The studies were scanned in the Web of Science and Scopus databases under the heading “Title/Abstract/Keywords,” and the data were analyzed in detail. The findings indicate research trends in the literature and gaps for future research. The results highlight the innovative approach for sustainable post-disaster temporary architecture in the context of reuse strategies and present the field’s challenges, limitations, and opportunities. This study is expected to help researchers, practitioners, experts, and politicians understand the evolutionary implications of disaster reuse strategies and develop other theoretical and practical initiatives that can be applied in this field.

The effort to preserve historic buildings for the future has always been on the agenda of experts on local and global scales and been supported by many initiatives and strategies. Within the scope of this research, the concept of “adaptive reuse” which is often preferred as a conservation strategy for historic buildings, is discussed. The focus is on the adaptive reuse studies of historic buildings in literature that have managed to physically survive in the face of changing conditions; comprehensive and systematic research with a bibliometric analysis is presented. The study has been scanned in the Web of Science database under the heading “Title/Abstract/Keywords” and the data has been analyzed in detail with the VOSviewer program. The findings indicate the research trends in the literature and gaps for the future research. The results highlight the innovative approach for historic buildings in the context of the adaptive reuse strategy and present the field’s challenges, limitations and opportunities. It is expected this study will help researchers and policymakers to understand the evolutionary implications of conservation strategies and develop other theoretical and practical initiatives to be applied in this field.

Urban freshwater ecosystems have many critical functions, such as providing water to all living things and supporting biodiversity. Factors such as water pollution, increased water consumption, habitat loss, climate change, and drought threaten the health of urban freshwater ecosystems. Looking for solutions to these challenges, this article aims to recycle water and return it to its life cycle using a climate-sensitive water collection strategy. The model focuses on the biomimetic method as a basic strategy. In this regard, the concept of water-harvesting has been examined in detail by conducting a deep literature review, including architecture and engineering disciplines. With all these data obtained, a synthesis/integration study was carried out by developing a model proposal based on adaptive building façade elements to solve the water problems experienced in cities. The model proposal, which is directly related to the titles of “Clean Water and Sanitation (SDG 6)” and “Sustainable Cities and Communities (SDG 11)”, which are among the Sustainable Development Goals (SDGs), aims to provide different perspectives on the disciplines with its superficial and functional features. In this context, it is anticipated that the article will become an indispensable resource for other researchers working on the subject.

Construction and demolition waste (CDW) represents one of Europe’s largest materials flows and a critical challenge for achieving circularity in the built environment. Drawing on comparative case studies from Latvia, Estonia, Greece, Cyprus, Slovenia, Romania, and Turkey, this paper analyzes how diverse CDW management models: centralized recycling hubs, on-site demolition processing, closed-loop manufacturing systems, public-led circular construction initiatives, and digital or technology-enabled waste prevention strategies influence material recovery outcomes, environmental performance, and market dynamics. Using a structured cross-case analytical framework, the study compares technological, regulatory, and operational features across cases to understand how collection, sorting, and processing systems shape circularity potential. Results demonstrate that advanced automated sorting, integrated value-chain models, and digital tools can substantially increase landfill diversion rates, reduce CO₂ emissions, and preserve virgin resources. However, persistent barriers including insufficient market demand for secondary materials, lack of end-of-waste criteria, regulatory inconsistencies, and cultural resistance, limit broader uptake. Stakeholder insights further highlight the role of political incentives, economic competitiveness, and technological readiness in enabling or constraining CDW circularity. The findings contribute to a clearer understanding of how European CDW sorting and processing practices can support a high-value circular construction transition and identify priority areas for policy and industry action.

The high consumption of raw materials and the generation of construction and demolition waste (CDW) represent significant sustainability challenges. The circular economy (CE) offers a promising pathway but requires effective legislation. Although considerable attention has been devoted to the technical and economic aspects of CE, comparative analyses of national regulatory frameworks remain scarce. This study addresses this gap by conducting a comparative analysis of the regulatory environments of nine countries: Cyprus, Estonia, Greece, Latvia, Poland, Romania, Slovenia, Switzerland, and Türkiye. With a retrieval-augmented generation (RAG) architecture based on a large language model (LLM), national and regional legal texts were analysed and fact-checked by experts. The results reveal substantial differences in regulatory maturity, enforcement mechanisms, and data platforms, resulting in the identification of three country clusters. The findings indicate that effective CDW management depends on legislative harmonisation, institutional capacity, data openness, and economic incentives. In addition, the study suggests that LLMs can serve as powerful instruments for comparative legal analysis in multilingual sustainability research.

Construction and Demolition Waste (CDW) represents a key barrier and opportunity in advancing circularity within the built environment, as countries intensify efforts to reduce waste and recover resources more effectively. Its valorisation increasingly relies on the combined influence of technological capabilities, economic feasibility and social acceptance. This study brings together national data from eight countries: Cyprus, Estonia, Greece, Latvia, Romania, Slovenia, Switzerland, and Türkiye to explore how economic, technological and social perceptions shape the potential of CDW in circular construction. The analysis examines the main economic opportunities and challenges in CDW recycling, including national market gaps and the availability of certified CDW-based products. It also highlights the growing role of digital tools, such as material-tracking systems, which support more reliable and transparent reuse pathways. From a social perspective, public perceptions and user preferences regarding recycled materials are analysed, along with stakeholder roles across the CDW value chain and the social implications of waste management. The study shows that an integrated approach that combines economic incentives, digital technologies, and stakeholder and community participation can effectively transform CDW into a valuable secondary raw material. It aims to guide policymakers, local governments, and industry professionals in creating diverse, practical initiatives from a comprehensive perspective, while also helping establish a strategic waste management framework.
