“…This methodology contributes to the improvement of information processing, better communication flow [ 11 ], data interoperability throughout the work team, and provides the opportunity to have a common language available to all at any time; allows being aware of project changes in real time and performing verifications before implementation, whether it is convenient or not, according to its principle of inference detection [ 22 ]; and also contributes to improve the sustainability of the project [ 33 , 34 ]. The methodology is used in a very limited way [ 35 ]. Its use should go beyond the 3D (level where the 3D model is made), where it is frequently used.…”

“…"Reduce" refers to the reduction of consumption and waste generated, "reuse" includes the reuse of building products or material at the end of life, and "recycle" involves processing to break down and reproduce materials and new products [23]. There have been many iterations of the R principles that subdivide the 3 Rs into 14, 22, and even up to 38 Rs [24,25]. The 38 identified by Reike et al [26] are listed here in alphabetic order: "re-assembly, recapture, reconditioning, recollect, recover, recreate, rectify, recycle, redesign, redistribute, reduce, re-envision, refit, refurbish, refuse, remarket, remanufacture, renovate, repair, replacement, reprocess, reproduce, repurpose, resale, resell, re-service, restoration, resynthesize, rethink, retrieve, retrofit, retrograde, return, reuse, reutilize, revenue, reverse and revitalize".…”

Building construction accounts for a significant proportion of global greenhouse gas emissions, raw material extraction, and waste production. Applying circular economy (CE) principles in the building construction industry would considerably reduce these values. However, uptake by the industry is relatively slow, which is largely attributed to sectoral barriers, including limitations in knowledge and experience. This review paper aims to assess and contribute to diminishing these obstacles by offering a comprehensive review of circular material usage principles and strategies within the construction sector. Opportunities and facilitators of change are also presented, including innovations and emerging technologies in recycling, digitization, robotic systems, novel materials, and processing. Finally, four case studies demonstrate the application of circular theory via a novel block system, recycled aggregate, modular kitchen reuse, and an energy efficiency retrofit. The conclusions show that future efforts should prioritize the development of strong regulatory frameworks, awareness initiatives, and international cooperation. In this regard, the integration of technological advancements, such as AI, robotics, and blockchain, is essential for optimizing waste management efficiency. Furthermore, education on circular practices plays a critical role. Through global collaboration, standardizing circular construction approaches can promote a more sustainable and resilient building construction industry.

“…Buildings, like other products, are affected in their life cycle by the consumption of resources and environmental pollution during their manufacture, use and disposal. 6,7 Since buildings are more durable products than most, the unintended consequences of unsustainable construction may become apparent too late to sufficiently influence short-term motivated deci-sions. The awareness of these problems has grown recently, but changes are only being implemented slowly.…”

Low‐vacuum scanning electron microscopy (low‐vacuum SEM) is widely used for different applications, such as the investigation of noncoated specimen or the observation of biological materials, which are not stable to high vacuum. In this study, the combination of mineral building materials (concrete or clay plaster) with a biological composite (fungal mycelium composite) by using low‐vacuum SEM was investigated.Fungal biotechnology is increasingly gaining prominence in addressing the challenges of sustainability transformation. The construction industry is one of the biggest contributors to the climate crises and, therefore, can highly profit from applications based on regenerative fungal materials. In this work, a fungal mycelium composite is used as alternative to conventional insulating materials like Styrofoam. However, to adapt bio‐based products to the construction industry, investigations, optimisations and adaptations to existing solutions are needed. This paper examines the compatibility between fungal mycelium materials with mineral‐based materials to demonstrate basic feasibility. For this purpose, fresh and hardened concrete specimens as well as clay plaster samples are combined with growing mycelium from the tinder fungus Fomes fomentarius. The contact zone between the mycelium composite and the mineral building materials is examined by scanning electron microscopy (SEM).The combination of these materials proves to be feasible in general. The use of hardened concrete or clay with living mycelium composite appears to be the favoured variant, as the hyphae can grow into the surface of the building material and thus a layered structure with a stable connection is formed.In order to work with the combination of low‐density organic materials and higher‐density inorganic materials simultaneously, low‐vacuum SEM offers a suitable method to deliver results with reduced effort in preparation while maintaining high capture and magnification quality. Not only are image recordings possible with SE and BSE, but EDX measurements can also be carried out quickly without the influence of a coating. Depending on the signal used, as well as the magnification, image‐recording strategies must be adapted. Especially when using SE, an image‐integration method was used to reduce the build‐up of point charges from the electron beam, which damages the mycelial hyphae. Additionally using different signals during image capture is recommended to confirm acquired information, avoiding misinterpretations.
