“…Additionally, interviewee C was identified as a recommendation from interviewee B. To date, only a few built examples are available due to the complexity that CBD entails (Cambier et al ., 2021), and amongst the examples, the representation of MBs was found to be low. Therefore, some interviewees were approached even if their circular building project was in the conceptual phase.…”

PurposeThere is a renowned interest in adaptability as an important principle for achieving circularity in the built environment. Circular building adaptability (CBA) could enable long-term building utilisation and flexible use of space with limited material flows. This paper identifies and analyses design strategies facilitating CBA to propose a framework for enhancing the implementation of the concept.Design/methodology/approachInterviews were conducted with professionals experienced in circular building design to explore the questions “How do currently applied design strategies enable CBA?” and “How can CBA be implemented through a conceptual design framework?”. The interviews encircled multi-residential building examples to identify currently applied circular design strategies. The interviews were analysed through qualitative content analysis using CBA determinants as a coding framework.FindingsThe results show that all ten CBA determinants are supported by design strategies applied in current circular building design. However, some determinants are more supported than others, and design strategies are often employed without explicitly considering adaptability. The design strategies that enable adaptability offer long-term solutions requiring large-scale modifications rather than facilitating low-impact adaptation by dwelling occupants. The proposed conceptual design framework could aid architects in resolving these issues and implementing CBA in their circular building design.Originality/valueThis paper’s contribution to CBA is threefold. It demonstrates design strategies facilitating CBA, proposes a conceptual design framework to apply the concept and identifies the need for a more comprehensive application of available adaptability strategies.

“…The combination treatments between the auxin and cytokinin are very importance in order to get the high amounts of callus for using in other experiments, and auxins directly affect cell expansion by increasing some enzymes activities, in response to wall flexibility and increasing permeability [54]. Due to their ability to trigger the manufacture of some important proteins and the creation of RNA, cytokinins are crucial for cell division [55]. Results displayed that callus induction demands the existence of 2,4-D as auxin used to fundamental inducement.…”

Nanotechnology, consider as one of the newest important methods towards improve the production of callus using plant tissue culture. The objective of the current work was to create a unique callus induction methodology. and proliferation from Capisum annum in vitro. Therefor different concentrations of Mg nanoparticles were used which synthesized using green method. For callus inducement, young foliage, and stem from the sterile germinated seedlings using Sodium hypochlorite (NaOCL) 6% for 10 min were used as explants. They were cultivated in MS media supported by several combinations of kinetin and 2, 4- Dichlorophenoxyacetic. The maximum percentage responsive reached 100% from leaf explants at 2, 4-D 1.5 mg/L and Kin 1.0 mg/L. While 2, 4-D 1.5 mg/L and Kin 0.5 mg/L achieved the highest fresh weight for callus proliferation. The best MgNPs concentration for callus inducement and proliferation of capsicum leaves and stem explants was MS media supported with 1.0 and 0.3 ml/L respectively. While the highest proliferation mean value for callus was recorded at the concentration of 6.0 ml/L MgNPs in MS medium reached 6.1 gm. AFM photographs prove that MgNPs were in nanometer size and had the spheres and the rods shape. The average grain size of the MgNPs was 23.8 to 38.24 nm.

The uptake of a circular economy (CE) in the building sector is challenging, primarily due to the complexity associated with the design process and the dynamic interaction among architects, engineers, and construction (AEC) stakeholders. The standard and typical design process and construction methods raise concerns about building life cycles. Buildings should not only fulfill current needs, but one also needs to consider how they will function in the future and throughout their lifetime. To address these complexities, early planning is required to guide designers in holistically applying systems thinking to deliver CE outcomes. This paper outlines a critical review of CE implementation in buildings, with a proposed trifecta of approaches that significantly contribute to the development of circular buildings (CBs). The findings outline a proposed visualized framework with a conceptual formula that integrates CE design strategies to simplify and enhance AEC stakeholders’ perception of the circularity sequence in buildings. By strategically integrating loop-based strategies with the value retention process (VRP) and design for X (DFX) strategies, along with efficient assessment tools and technologies, it becomes feasible to embrace a CE during the design phase. The outcome of this review informs AEC stakeholders to systematically and strategically integrate the critical dimensions of a CE throughout the building life cycle, striking a balance between environmental concern, economic value, and future needs.
