Indeed, commitments to net zero arent really achievable without these assessments. Circular economy pillars: A semi-systematic review. As projects like the refurbishment of 1, Triton Square demonstrate, there is also a increasing interest and perceive commercial value to approaching buildings as forms that can be reimagined in situ, without the need to demolish, waste resources and start over from a blank slate. A total amount of 2337 million tonnes of waste was generated in European Union in 2018, being construction and demolition (C&D) waste one of the most impactful waste stream, accounting for roughly one third (35.9% in weight) of the generated waste [, One important aspect is that this waste stream has a very heterogeneous composition [, In the European Union, the new Circular Economy Action Plan [, Several issues related to the aim of achieving a more sustainable construction have been addressed previously. ; Ibez-Fors, V.; Arena, A.P. This should not just accelerate circular construction but also help develop a new and honest architectural language that celebrates the composite design approach and not tries to mimic an existing aesthetic using different materials.

The model was based on the three previously mentioned dimensions. Please let us know what you think of our products and services. Another important step to be considered would be the validation of the model displayed in this work, which might be accomplished considering examples encompassing the application of the principles supporting that model. However, transition and implementation of circular construction practices are slowed down by technical, social and legislative barriers. World Commission on Environment and Development: Our Common Future, Transforming Our World: The 2030 Agenda for Sustainable DevelopmentResolution Adopted by the General Assembly on 25 September 2015 (A/RES/70/1), Towards the Circular Economy Vol. There should be a strong will in order to acknowledge waste as a resource, assigning it more noble roles, such as reuse and recycling. The study performed in this work allows us to conclude that the proper transition to a circular construction paradigm involves the creation of legislation and standards, the availability of funding instruments, such as public investments or green fiscal policies, the motivation by construction professionals to develop and implement innovative but reliable solutions, well-trained staff and technicians, facilities with proper conditions to deal with recycled materials and the correct management of waste resulting from C&D activities. A related implication is that design-for-reuse should also lead to architectural forms that are inherently easier to deconstruct ,and thus where a far greater percentage of materials end up reused. Waste Generation, 2018 (Eurostat). The funders had no role in the design of the study; in the collection, analysis, or interpretation of data; in the writing of the manuscript; or in the decision to publish the results. Sustainable operations: Their impact on the triple bottom line. Almost all the steps in the process of taking existing building components from bin to BIM do in fact already exist and we are currently working on a system that connects the dots in the process flow. The most challenging task towards a circular construction is a full commitment of the stakeholders with the premises of circularity. The key is to keep sight of digital tools power to scan, identify and catalogue elements at scale. We considered that the more developed and calibrated the premises enclosing these three dimensions are, the faster the implementation of such an outlook. This novel conceptualization depends on the existence of different stakeholder partnerships that should be exploited to prepare the industry to new challenges involving the development of disruptive materials and products made from recycled C&D waste targeting their use in the B&C sector as well as the implementation of sustainable practices at the construction site. It should also be considered the possibility of these recycled centres attest the quality control of the materials that are produced, which will be a positive aspect targeting the increase of the reliability on those recycled materials. A conceptual foundation for effective construction and demolition waste management. 2023 Springer Nature Switzerland AG. Gimenez, C.; Sierra, V.; Rodon, J. Effect of synthesis parameters on the quality of construction and demolition wastes (CDW) geopolymers. - 208.113.186.1. The authors declare no conflict of interest. The development of strategies for achieving a circular construction should be based on three dimensions: (1) the assignment of roles to the government and construction professionals; (2) the development and improvement of industry to deal with C&D waste; and (3) the implementation of sustainable practices at the construction site. Waste Recycling in Europe. In addition to the action of governments, working groups and technical committees should be formed to work on the development of those instruments. Sustainability. The aim of this paper is to better understand the dynamics of circular construction projects and how these interorganizational projects contribute to the transition towards a circular economy.

What are the needs downstream of the construction site to close the loop on the materials and products employed in the B&C sector? Two hundred years ago if you knocked a building down, you just reused as much of the stone, bricks and timber as possible.

These three dimensions are related to their counterparts associated with sustainable development (society, economy and environment). Resources, Conservation and Recycling, 109, 6777. Circular economy (CE) is gaining traction in the construction industry, providing a responsible business model to decouple construction activities from excessive consumption of finite resources.

Recycling materials used to be a common practice in the built environment. Construction and Building Materials, 44, 464476. The chapter focuses on construction and demolition waste (CDW) and how potential new technologies developed for other applications can be utilised to bring circularity to CDW management.

Considering the properties of the recycled materials, which should be fully characterised within the framework of research and development activities, architects and designers should boost the use of these resources in engineering projects as much as possible, without neglecting the proper behaviour of the applications in which they are going to be applied.

A circular construction industry requires a radical redefinition of how resources are managed within the construction industry and the built environment. Editors Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. Mechanical recycling of EOL concrete into high-grade aggregates. To accomplish the research aim of this work, we decided to design a model that could be capable of giving answers to the demands of a circular construction. The collection, connection and creative use of data is transforming what is now possible in the built environment. (2019).

(2018). A branch of mathematics called non-well-founded set theory allows for the construction of circular sets. It is expected that the manufacturers responsible for developing materials and products involving the use of waste will have their own recycling facilities in the future to turn the C&D waste into a raw material. Weber, W.J. ; Arulrajah, A.; Bo, M.W.

(2017). Today, in the era of steel, concrete and glass structures, we have got into the bad habit of sending almost everything to landfill (only 6% of construction materials are reused in an industry responsible for 40% of CO2 emissions). In addition to the discussion about the different stakeholder partnerships that must exist, key ideas that should be adopted by industry to deliver recycled materials and products to the building and construction sector are proposed in this work. Molineux, C.J. The goal should not be the revolutionary replacement of the traditional materials and components by recycled materials but instead a progressive use of these resources as confidence and reliability on their performance increases. https://doi.org/10.3390/su14095314, Almeida, Filipe, Castorina S. Vieira, Jos Ricardo Carneiro, and Maria de Lurdes Lopes. Imagine digitally mapping not just buildings but whole cities, leading to catalogues of available in future building components. Peculiarities associated with each one of those dimensions and ideas as well as the interactions occurring between them will be discussed in order to understand how the model could work. (2021). This will be an important milestone leading to the adjustment and the improvement of plans being conducted in the B&C sector within the context of circular construction.
