There is a significant deficiency in addressing the unique characteristics of construction and demolition waste (C&DW) United Kingdom (UK) as it remains primary contributor to landfills. Circular economy (CE) practices are explored address this risk shortfall management comprehend reduction strategies for C&DW. Using Fuzzy Delphi approach, study maps assesses uncertainties associated with identifying indicators ranked CE adoption barriers achieve agreement twelve respondents. Consensus was also achieved C&DW measurement indicators. Concurrently, eleven separate interviews were conducted understand CE's effectiveness improving management. The results indicated that most barrier inefficient recycling policies ensure high-quality recycled materials. findings underscore influence design, managerial, legal surpasses social, knowledge, culture. Despite highlighting focus on recycling, reusing, reducing raw materials, deeply established tendencies prioritise linear economic models exist widely, resource conservation less considered. This provides concrete implementation responsible consumption production, challenges adoption, offers 25 industry-specific measuring implementation.

Опубликована: Фев. 3, 2024

The adoption of circular economy (CE) holds significant potential to mitigate the challenges posed by conventional linear economic model. building sector in Saudi Arabia continues experiencing rapid growth, often marked a consistent annual rise number projects. incorporation CE principles into this expansion presents opportunities optimize resource utilization, minimize waste generation, and enhance overall environmental sustainability. This study explores current levels awareness, perception, implementation among local stakeholders assesses for region. Additionally, it seeks rank identified barriers enablers while exploring interconnected relationships between such barriers. A literature review was conducted explore enablers. followed an online survey which amongst 139 respondents from diverse stakeholder groups. relative importance index (RII) employed enablers, findings were subjected statistical analysis using Statistical Package Social Sciences (SPSS). outcomes highlight lack awareness regarding stakeholders, with very low rate. To break inertia encourage practices, suggests need CE- supportive policy legislation, provision financial incentives.

Cultivating Sustainable Construction: Stakeholder Insights Driving Circular Economy Innovation for Inclusive Resource Equity

Buildings, Год журнала: 2024, Номер 14(4), С. 935 - 935

Опубликована: Март 28, 2024

Due to its intricate production processes, complex supply chains, and industry-specific characteristics, the construction industry faces unique challenges in adopting circular economy (CE) principles that promote resource equity. To address this issue, study aims delve into identifying stakeholders’ opinions perceptions regarding key CE strategies across different stages of building life cycle (BLC). Both European non-European stakeholders within “CircularB” COST Action network beyond participated research. Three methods were employed assess opinions: an online survey, a structured survey with semi-guided workshop, creative thinking round table discussions. Natural language processing (NLP), specifically topic modelling sentiment analysis, was used analyse data collected from which gathered text-based 209 participants on cost-benefit aspects circularity strategies. The 43 workshop participants, evaluated perceived importance various BLC phases assessed adoption selected current or past projects. Finally, Six Thinking Hats® activity, discussions, generated ideas 25 professionals broader implementation opportunities construction. research findings highlight need bridge gap between theory practice by fostering active stakeholder involvement transition model. analyses through three activities contribute proactive collaborative efforts aimed at advancing equity sector promoting just inclusive use. In summary, offers comprehensive understanding provides guidance for development targeted policies accelerate integration industry.

Turning Agricultural Biomass Ash into a Valuable Resource in the Construction Industry—Exploring the Potential of Industrial Symbiosis

Buildings, Год журнала: 2025, Номер 15(2), С. 273 - 273

Опубликована: Янв. 18, 2025

This paper presents a circular business model (CBM) designed to promote the valorization of agricultural biomass ash for producing an alternative binder in construction, aiming reduce CO₂ emissions and landfill waste. The economy framework emphasizes regeneration restoration minimize resource energy use, waste generation, pollution, other environmental impacts. Aligned with these principles sustainability, construction industry, sector food processing industry can establish shared interest through industrial symbiosis. In proposed CBM, from one becomes input another. leverages symbiosis by using sunflower husk (SHA) as hydroxide activator alkali-activated materials. A case study companies Republic Serbia that produce SHA forms basis this model, featuring promising results experimental testing three mortars produced activating ground-granulated blast furnace slag (GGBFS) different contents (15, 25 35 wt% GGBFS), instead commercially available activators. potential was assessed flow diameter compressive strength at 7 28 days curing. highest 28-day attained addition 25% (28.44 MPa). provided valid CBM development. is stream-based, resulting merging upgrading two existing symbioses. highlights benefits while addressing challenges barriers its implementation, offering insights into possible integration sustainable practices.

Exploring Circular Economy Strategies in Buildings: Evaluating Feasibility, Stakeholders Influence, and the Role of the Building Lifecycle in Effective Adoption

Applied Sciences, Год журнала: 2025, Номер 15(3), С. 1174 - 1174

Опубликована: Янв. 24, 2025

The concept of circular economy (CE) has emerged as an effective strategy for addressing resource depletion, waste generation, and environmental challenges, offering a promising path towards more sustainable future. In the building sector, adopting CE principles can significantly mitigate impacts, minimize lifecycle costs, promote sustainability throughout building’s lifecycle. Using mixed-method approach via pre-interview questionnaire semi-structured interviews with 10 experts, this study analyses significance 15 strategies in construction projects, assessing their importance ranking potential adoption. Furthermore, evaluates feasibility applying to different types, including storage, industrial, commercial, residential, business, healthcare facilities. role stages initiation planning, design, procurement, construction, operation maintenance, end life is examined identify phases highest successfully embracing principles. stakeholders driving change also analyzed. outcomes reveal that most feasible include use renewable energy, design durability longevity, prefabrication, offsite construction. findings indicate business (office) buildings are application, while planning identified critical Owners designers emerge greatest influence on implementation. results provide comprehensive overview adoption sector. These offer valuable insights inform development targeted support
