Circular Economy (CE) is a necessary intervention for enabling resource efficiency, energy conservation, waste minimization, and sustainability within the construction industry (CI). Among its many facets, circular procurement (CP) nascent concept that enables CE in CI. Despite extensive literature review studies conducted on intricacies, critical documenting barriers to adoption of CP CI remain scarce. This study systematically reviews existing retrieved from Scopus database. A systematic was 46 shortlisted articles published between 2010-2023 using Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) protocol, key were identified. The results reveal both hard (HB), such as lack design production, reverse logistics, standardization, reliable information management, profitable business models, soft (SB), stakeholder engagement, trust routes, resistance change, perceived performance issues collaboration impediments Further, measures strategies mitigate identified also are presented current study.

Опубликована: Янв. 15, 2025

Purpose The increase in waste and carbon emissions from the construction industry continues to fester although sustainable design approaches such as designing for adaptability (DfA) have been approved a viable option minimize greenhouse gases while providing cost savings on building projects. This paper examines views of professionals challenges implementing DfA Ghanaian (GCI). Design/methodology/approach A critical comparative review related literature was conducted international adaptability. After review, 16 were identified used basis questionnaire survey context. By using quantitative approach, close-ended structured seek 236 operating GCI regarding these factors. Data retrieved analysed descriptive inferential statistics. Findings findings revealed key among Ghana include “limited funding adaptable buildings”, “lack collaboration between professionals, contractors clients towards realization demand buildings” education training programs practices”. Originality/value novelty or originality this study lies its focus GCI, an area where concept has rarely examined practice despite recognized potential benefits reducing emissions. offers detailed comprehensive understanding multifaceted faced by Ghana. level detail is crucial devising targeted strategies promote region.

Challenges in the Design for Disassembly of Light Timber Framing Panelized Components

Buildings, Год журнала: 2025, Номер 15(3), С. 321 - 321

Опубликована: Янв. 22, 2025

The construction sector generates more than one-third of global waste. Although there is a consensus on the need to reduce it, empirical research evaluating current systems develop circular solutions remains limited. Using full-scale model, this article evaluates disassemblability corner joint between two prefabricated lightweight timber-framed walls, system widely adopted in residential North America. analysis deconstructed disassembly actions, identified their level difficulty, and classified recovered materials into three categories: reusable, recyclable, results reveal that lack design criteria for significantly limits system’s circularity, as it prioritizes assembly speed energy performance. predominant use nails fasteners complicates separation layers, damages materials, restricts reuse. This highlights urgent redesign enable efficient disassembly, promote component recovery, extend time circulation. study establishes foundation evolution panel toward aligned with circularity principles.

Bamboo as Sustainable Building Materials: A Systematic Review of Properties, Treatment Methods, and Standards

Buildings, Год журнала: 2023, Номер 13(10), С. 2449 - 2449

Опубликована: Сен. 26, 2023

Bamboo is the building material of past and future. It offers numerous properties that make it versatile for various applications, including construction. Its impressive strength-to-weight ratio enables to bear substantial loads stresses, while its good elasticity allows efficient energy absorption. However, mechanical can vary based on factors such as species, age, locations, methods, treatment. Treating bamboo essential enhance durability. The literature provides natural chemical treatments some but also reported drawbacks regarding higher temperature, content, duration. This paper reviewed 57 articles from Scopus database, specifically focusing article–document-type publications years 2003 2023. Additional references were incorporated address concerns in properties, treatment, standards provide systematic understanding. With extensive assessment articles, following gaps observed, recommendations further study made: bamboo’s development centralized guidelines procedures preparation processing; exploration alternative materials reinforce without compromising ductility; joint connections, testing considering seismic, wind vibration. For treatment standardization using natural, chemical, or a combination. Lastly, codes standards, existing bamboo, highlighting potential limitations areas, uniformity, differences with all similar standards. By filling these gaps, support reliability robustness sustainable material, fostering promotion adoption construction industry.

Опубликована: Янв. 31, 2024

As the construction industry moves toward sustainable building practices, incorporating wood-based materials into envelope systems has become a priority. This paper investigates environmental impact of three custom bio-composite Façade System Modules (FSMs) through an Embodied Carbon Assessment (ECA), focused on Global Warming Potential indicator life cycle stages from cradle to practical completion (A1–A5). The evaluated FSMs were developed within Basajaun H2020 project (G.A. 862942), by substituting and combining conventional with other products form hybrids bio-based polymers wood. A benchmark ECA was conducted, simulating alternative devised common practice solutions for curtain wall façade facilitate comprehensive comparison. inventory encompassed detailed technical information, fostering utilization primary data accuracy. study particularly highlights considerations over technological modules that incorporate increased use components novel material: frame profiles, insulation equipment, seal system. Despite challenges due FSMs’ weight, findings reveal replacing currently used bio-composites reduced embodied emissions, aluminum profiles. insights presented here offer indicators circular, environmentally conscious, bio-composed envelopes, emphasizing need continued analysis refinements as consequence increasing accuracy available supply chain concerning end-of-life scenarios.

Опубликована: Янв. 1, 2025

The predominance of a linear economic model and the limited integration circular strategies in design execution building projects—particularly construction sectors developing countries—have resulted ongoing pressure on natural resources, high levels waste generation, reduced productivity, frequent time cost overruns. Collectively, these issues contribute to unsustainable development, adversely impacting social, economic, environmental dimensions sustainability. This study explores perceptions professionals regarding benefits, awareness, implementation Design for Deconstruction (DfD) within Nigerian industry (NCI). Data were collected through structured questionnaire distributed electronically experts Nigeria's South-South geopolitical zone using snowball sampling technique. With 40.10% response rate reliability index above 0.800, data analysed Exploratory Factor Analysis (EFA) Partial Least Squares Structural Equation Modelling (PLS-SEM). Findings reveal that awareness DfD is moderate, but its adoption remains low. EFA identified five key categories benefits: (1) business (2) (3) (4) green certification technology integration, (5) social benefits. PLS-SEM results show all have positive significant influence decision adopt NCI. contributes theoretical advancement practical understanding practices, particularly DfD, with implications reducing waste, improving resource efficiency, supporting achievement Sustainable Development Goals (SDGs) 3, 9, 11, 12, 13.
