Pathways to circular construction: An integrated management of construction and demolition waste for resource recovery. This support can be granted by means of funding instruments, such as public investments or green fiscal policies, which should be studied and developed by governments, or by the allocation of capital by investors. Reduce, reuse, recycle and recover are essential interventions for a circular construction, with a systemic shift in the culture and mindsets of stakeholders. The excessive use of natural raw materials by the B&C sector is responsible for generating impressive environmental impacts that seem to be difficult to be recovered. Influence of Nano-Silica on the properties of recycled aggregate concrete. So how do we increase the quality and quantity of recycled content in the construction process? those of the individual author(s) and contributor(s) and not of MDPI and/or the editor(s). Facilities, 29, 224242. (2018). You are accessing a machine-readable page. Urban mining and circular construction are two approaches to the challenges facing architecture and urban design, using techniques such as reversible details and design for disassembly and tools such as material passports and databases. A schematic representation of the stream including how the ideas, measures and strategies discussed in this section can be put into practice is displayed in. The development and implementation of principles and guidelines of good manufacturing practices are essential tools in order to ensure that the materials and products developed at the production lines fulfil the intended requirements. If applicable, they should comply with the correct guidelines provided by the designers and the manufacturers while installing the recycled materials and products. An introductory note on the environmental economics of the circular economy. The use of natural resources can be remarkably decreased in case of using recycled waste as raw material, which is a major step to stop that serious drawback. https://doi.org/10.1016/j.conbuildmat.2017.01.055, Department of Civil and Environmental Engineering, Brunel University London, Uxbridge, UB8 3PH, Middlesex, UK, You can also search for this author in ; Gange, A.C.

Systems approach to scaling-up global upcycling: Framework for empirical research. RedwoodGrove Senior Member Northern California English, USA 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. To increase the reliability on the use of recycled materials and products further actions will be required. Author to whom correspondence should be addressed. The activities conducted in the building and construction sector should be guided by circular economy principles, which will result in the implementation of greener practices fostering both the development of economy and protection of the environment. ; Olsen, D.; Ahmad, I. Firstly, we need to 3D scan the materials geometry, then evaluate its structural properties and strengths, before collating these data points in a new digital model, and then formatting this data in ways that programs like Revit or Oasys GSA can understand. https://doi.org/10.1007/s10098-016-1323-8, Tons of solid waste generated.

Ghisellini, P.; Cialani, C.; Ulgiati, S. A review on circular economy: The expected transition to a balanced interplay of environmental and economic systems. Through close collaborations with academic, industrial, and legislative/ political partners the lab ensures the relevance of its work and promotes the direct and full-scale implementation of research results towards a more sustainable, low/ no-carbon, circular construction industry. The literature review that was performed revealed the existence of approaches, legislation, measures, documents and guidelines that are currently used to implement sustainable practices in the B&C sector. The most challenging task towards a circular construction is a full commitment of the stakeholders with the premises of circularity. You seem to have javascript disabled. 9-2003), prescribed by OMB Circular A-102 Resources, Conservation and Recycling, 135, 7082. Proud members of BOMA and ICSC. https://doi.org/10.3390/su2051204, Menegaki, M., & Damigos, D. (2018). Lacking a detailed account of existing materials current state, attempts at circular construction to date mostly involve recasting or chopping elements up for reuse, leading to the higher costs, and production of yet more CO2 emissions, diminishing the value of recycling in the first place. Circular economy indicators in relation to eco-innovation in European regions. It should be expected that state of the art circular construction techniques (such as recycling by crushing, mixing, etc.) The introduction of circular economy concepts during the design phase could be a contribution, for instance, to understand the reuse percentage of the materials that are going to be applied during each project [, Planning is essential: waste management should not be performed only at the construction site. The Innovate 18 project: Light weight aggregate for concrete. ; Laux, S. Leachate from land disposed residential construction waste. The key is to keep sight of digital tools power to scan, identify and catalogue elements at scale. The use of energy in a linear model of resource consumption is very significant during the steps involving the extraction of the raw materials from the environment and their transformation into commercially solutions [, Another important aspect is that the development of materials and products made from recycled waste to be used in the B&C sector is going to have a positive effect on the waste reuse and recycling rates, which must be improved as much as possible.

Equally important is, on the one hand, the development of legislation that forces companies to comply with greener and sustainable practices and, on the other hand, standards framing issues like the use of waste as raw material. (2018). ; Wan, H.W. Circular construction is a strategy for the construction sector in which energy consumption and recycling opportunities are crucial in the choice of materials and methods. Construction and Building Materials, 23, 872877. The first version of the lexicon was published in July 2019, based on the efforts of the action teams in 2018- An illustration showing how to construct a square circumscribed about a circle. 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. Prioritizing barriers to adopt circular economy in construction and demolition waste management. 20 Years of experience and is the 3rd generation of construction.

Transition to circular economy in the construction industry: Environmental aspects of waste brick recycling scenarios. A team composed by engineers, technicians and oversight construction staff will also be responsible to implement the best practices within the framework of demolition activities. We presume that, with the commitment and determination of stakeholders around these strategies, the achievement of a circular construction paradigm might become a reality in the next decade. Sustainable operations: Their impact on the triple bottom line. Circular construction is an emerging business strategy that promotes the reuse and recycling of as many raw materials as possible in a bid to minimise CO2 emissions and waste to landfill. Bynum, P.; Issa Raja, R.A.; Olbina, S. Building Information Modeling in Support of Sustainable Design and Construction. Indeed, commitments to net zero arent really achievable without these assessments. 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. The principles of the circular economy, the shift from take/make/dispose to design for reuse, have been slow to become the norm in the built environment sector. The methodology included in this work was drawn to respond to the following questions: What model could be designed to boost the transition to a circular construction paradigm? All these measures are contributions (some are important, while others are not so impactful) to combat climate change that is mainly caused by human activities and to achieve some of targets of the Sustainable Development Goals included in the United Nations 2030 Agenda for Sustainable Development [. future research directions and describes possible research applications.

In addition, tools should also be developed to monitor both the progress of the transition and whether the B&C sector is complying with the policies that will be in force. Circular construction - DTU Drawing a Path towards Circular Construction: An Approach to - MDPI Feature papers represent the most advanced research with significant potential for high impact in the field. The upcoming challenges involving the study and development of new commercial materials and products including waste will offer the opportunity of both improving the knowledge and foster the creation of new companies. https://www.mdpi.com/openaccess. 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). Advanced Powder Technology, 26, 368376. A branch of mathematics called non-well-founded set theory allows for the construction of circular sets. Building Information Modeling (BIM) for green buildings: A critical review and future directions. One of the main problems is the lack of quality of the waste resulting from those activities, whose very heterogeneous composition hinders its potential use in recycled materials or products. The use of new materials and products, different types of designing approaches or new operational processes will not be fully welcome. This process of quality control will assist the decision-making associated with the intended use of those materials and products. At the end of the process, a technical sheet revealing the properties of the materials and products should be generated. REPRESENTATIVE PROJECTS.

Journal of Cleaner Production, 182, 553566. There are environment agencies around the globe (e.g., the European Environment Agency [. Editors select a small number of articles recently published in the journal that they believe will be particularly Construction and Building Materials, 44, 464476. These three dimensions are related to their counterparts associated with sustainable development (society, economy and environment). There are many practical hurdles to overcome, like the need to develop so-called digital materials passports that capture and store information on the materials used for future users to work from perhaps decades into the future. https://doi.org/10.1016/j.ecolecon.2018.04.028, Kirchherr, J., Reike, D., & Hekkert, M. (2017). This work proposes and discusses an innovative approach based on a concerted strategy between stakeholders to accelerate the transition to a circular construction paradigm, which involves, as sustainable development, the definition of three dimensions to guide the process: (a) the assignment of key roles to the government and construction professionals; (b) the improvement of the industry to perform a proper management of construction and demolition waste; and (c) the development of sustainable practices at the construction site. Effect of synthesis parameters on the quality of construction and demolition wastes (CDW) geopolymers. For instance, solutions involving the combined use of natural resources and recycled waste appears to be an interesting starting point. "Reading like writers," students will explore the ways that stories are structured; then, "writing like writers," students explore organizational structures in their own writing. Construction and Building Materials, 55, 2937. Available online: Martnez-Lage, I.; Martnez-Abella, F.; Vzquez-Herrero, C.; Prez-Ordez, J.L. Sustainability., 2, 12041225. This task is of utmost importance in order to avoid the contamination of the recovered waste [. (2019). The insight delivered in this work provides key ideas to help clarifying the roles to be assigned to the government and construction professionals as well as some practices to improve sustainability at the construction site, which deals with a lack of planning in the use of materials and products, mistakes in the management of the C&D waste that is generated and an absence of projects and guidelines to perform the correct operational processes. What measures should be conducted at the construction site? https://doi.org/10.3992/1943-4618.14.4.155, Zhang, H., Ji, T., Liu, H., & Su, S. (2018).
