“…Through a series of established parameters, this research aimed to point out the possibilities of applying the elements of circular economy in a particular case from architecture, and thus contribute to better understanding of the concept. To that end, a preliminary analysis has led this study to establishing the fundamental list of circularity principles, among them, the biodegradability (recovery) is still insufficiently exploited in published literature [31].…”

To achieve material efficiency, the ongoing initiative to improve thermal properties of family houses in the Republic of Serbia should include harmonization with internationally established and nationally adjusted principles of circular economy. The overall aim of this study was to propose a methodology for optimal decision making between alternative materials and components for energy refurbishment of façades in existing family houses. Together with developed criteria, and their belonging indicators, the methodology was tested on selected case study houses located in the central zone of the city of Belgrade. Using the VIKOR method, five suggested scenarios and three sub-scenarios for façade thermal upgrades were assessed against five determined types of criteria: Economic Cost, Function, Circularity Features, Appearance, and Innovativeness. Obtained results—ranking lists of proposed scenarios—indicate that the optimal solution for energy refurbishment of façades in existing houses could include polyurethane insulation material in combination with the wooden window frames and low-E insulation glass. In future research, it will be necessary to introduce an additional assessment criterion related to the ecological quality of proposed scenarios, as the study revealed that a gap between circularity-related quality, and ecological sustainability, of building materials could be significant.

“…The life cycle of circular buildings should be a closed-loop system wherein components and materials are optimally used and retained at their highest value (Figure 1). The technical cycle consists of selecting materials and components that can be maintained to extend their service-life by reusing, refurbishing, repairing, and remanufacturing [21]. At the same time, recycling and incineration are final strategies.…”

“…Nevertheless, implementing CE strategies in buildings promises to be hindered by the ambiguity surrounding the concept. Despite the fact that the research output contributing to the development of a circular built environment is considerably increasing [21,22], there is still a lack of a thorough study that entails various facets of CE in buildings [7]. The present research will describe CE background, strategies, and approaches that can be applied in the construction industry according to recent studies, in an attempt to link theory to practice and provide better insights on the concept's uptake at the building level.…”

Population growth, along with a rapid urban expansion, is imposing a heavy pressure on the planet’s finite resources. It is widely acknowledged that the building industry consumes large amounts of raw materials while generating waste and emissions. To set apart economic growth from environmental repercussions, the Circular Economy (CE) arose as an innovative paradigm that can offer a fast-track towards a sustainable built environment. This paper will tackle a research gap that academia and policymakers often highlighted, which is how can we apply CE to assets that are predominantly meant to be demolished and their resources wasted when they reach their end-of-life. Globally, the paradigm aims at erasing the waste concept, relying on renewable and regenerative sources, and keeping the materials, components, and systems in use at their highest value as long as possible. The concept’s implementation would attempt to consider the built environment as a closed-loop system wherein resources are viewed as a scarce commodity. Although the CE seems straightforward, translating the circular thinking to the building level might be a hardship. The following paper will attempt to shed light on how to promote CE in buildings that will ultimately lead to healthier, more efficient, and more sustainable cities on a broader scale. The proposed framework considers CE implementation strategies throughout the building’s lifecycle and mainly deals with three innovative aspects: wise resource management, building design approaches, and digitalization of the building industry. In this sense, this study will explore these game-changing factors that are considered paramount to concretize the concept in practice and provide a smooth pathway for CE uptake in buildings.

“…The third type -the material circularity considers recycled content in the product together with the waste (linear flow) and usefulness of the product (expressed over a lifetime) [24,68,69]. Garcés-Ayerbe et al and Moraga et al, [23,35] make a point of change in the concept of end-of-life by the life cycle of restoration and closed-loop products and want to eliminate waste, maintain the value of products and materials, promote their use of renewable energy and remove toxic chemicals.…”

“…Compared to the linear scheme, the circularity is a more complex system [22][23][24] Complexity arises from material stocks, return flows and their management in different countries, as well as resource planning, logistics and recycling management, coordination of multi-level network activities, physical and information flow between network partners [25][26][27][28].…”

In this paper, the authors identified key elements important for circularity: (1) Background: The primary goal of circularity is to eliminate waste and to prove the constant use of resources. In the paper, we classify studies according to circular approaches. The authors identified main elements and classified them into categories important for circularity, starting with the managing and reducing waste and the recovery of resources; and ending with the circularity of material, and general circularity-related topics and presented scientific works dedicated to each of the above-mentioned categories. The authors analyzed several core elements from the first category aiming to investigate and connect different waste streams and provided a regression model; (2) Methods: The authors used a dynamic regression model to identify relationships among variables and selected the ones, which has an impact on the increase of biowaste. The research was delivered for the 27 European Union countries during the period between 2020 and 2019; (3) Conclusions: The authors indicated that the recycling rate of wasted electrical equipment in the previous year has an impact on the increase of recycling biowaste next year. This is explained as non-metallic spare parts of electronic equipment are used as biowaste for fuel production. And the separation process of the composites of electric equipment takes some time, on average the effect is evident in one year period.
