As long as supply chains are voluntarily changing, this will stall the transition, some obligatory outside influence can refine the incentives to change. This is critical to address, because the difficulty stalls the CE transition and suspends its benefits. So, it is essential for the demolition waste mitigation plan in the building's demolition phase. - BRIQS Fit-Out Mastery. Multiple case studies, spanning new builds and refurbishment, were undertaken to examine systemic mechanisms that lead to components being discarded. A review of the strengths of and challenges facing existing and emerging practices can be used to identify significantopportunities to integrate circular economy approaches within the built environment and construction sectors in Africa. This perceived lack of industrywide awareness, supported by the survey and breakout session findings that parts of the supply chain, such as clients and designers, have little knowledge on how to adopt circular economy principles is likely to impede uptake of circularity in the short term. Driving the Transition to a Circular Economic Model: A Systematic The key challenges identified by the survey respondents for adopting circular economy industrywide are shown in Figure 2. An appropriate rating was provided from '1' - the lowest level to '4' - the highest level. endobj The findings show that at an individual level, the majority of the survey respondents were aware of the circular economy concept. The research was undertaken through surveying the UK construction industry by way of an electronic survey and undertaking breakout sessions at an industry event. Moving towards a circular economy system provides an opportunity to address this through the reduction of the use of primary materials, protecting material resources and reducing the carbon footprint (EMF and MCK, 2014; Pratt and Lenaghan, 2015). 14 0 obj An analysis by the type of organisation shows slightly different results with manufacturers, researchers and consultants rating designers with a high level of awareness. It is then suggested that demonstration projects perform important roles in circular building niche formation, and under certain conditions constitute important factors for the dissemination of circular building. Little. endobj Out-of-date and fragmented policy and regulatory frameworks, as well as limited implementation and enforcement capacity, have resulted in unregulated and sometimes dangerous and unhealthy living and working environments. 45-60. Circular Economy: Industry Perspective On Opportunities & Challenges Secondly, the study focuses on the analysis of local experiments (i.e. World Economic Forum, Geneva, Switzerland. Circular economy concept and principles. A certain standardisation scheme to facilitate circularity, needs to be developed. Manufacturers were considered to be the most aware (2-19); this could be due to the existing work of various material sector trade associations on sustainability. x+ | Design considerations including the lack of consideration for end-of-life issues at a building level (3-19) and the complexity of buildings (3-23) were also thought to be significant challenges.

Utilising the results from a survey and a follow-up workshop, this paper provides an analysis of an industrywide perspective of circular economy awareness, challenges and enablers. Volume 471, John Wiley, New York, NY, USA. {9 "WpQ)K(,2V Journal of Cleaner Production 115: 36-51. It was noted that the European standards (CEN TC 350 (AFNOR, 2016)) has a renewed focus on end-of life-issues, known within the formal construction life cycle as Module D. One of the largest challenges for adopting circularity in the built environment is the unclear financial case, which ranked number one for the majority of stakeholders; having a clear business case was the most important enabler (3-61). Circular economy in the construction industry: An - ResearchGate The absence of incentives to design products and buildings for disassembly and reuse at their end of life is a significant challenge. org/images/stories/112212%20GCB%20Circular%20Economy% 20April%202016%20v3.pdf (accessed 22/05/2016). Circular economy in the built environment. endobj The application of the concept of circular economy thinking in construction, which is in its infancy, has been largely limited to construction waste minimisation and recycling. The circular economy (CE) is arising as a novel economic system that is restorative by design. This paper is the first in-depth review of the state of the art of environmental impact indicators for adaptive reuse of cultural heritage (ARCH) buildings from a circular economy perspective. Cost and associated profit was seen to be the dominant factor in any decision-making process which can be compounded by the short-termism of many clients. Waste Management 32(1): 1-2. <>stream and a testing challenge for the construction industry within Europe. While alternative business models have been explored in other sectors (Bocken et al., 2014; Lewandowski, 2016; Tukker, 2015), with Schult et al. The survey was available for completion over a 2-month period and resulted in 110 valid responses. Collaboration has been identified as a key requirement for progressing the circular economy (Chamberlin et al., 2013; Preston, 2012) and this should be explored within the procurement and supply chain management activities, as well as within the information sharing capabilities of BIM. Breakout sessions were held to discuss the challenges and enablers in the adoption of the circular economy in the built environment, with ~25 attendees at each session. Brick Development Association, London, UK. Collaboration has been identified as a key requirement for progressing the circular economy (Chamberlin et al., 2013; Preston, 2012) and this should be explored within the procurement and supply chain management activities, as well as within the information sharing capabilities of BIM. The starting point is the Horizon 2020 "CLIC" project (Circular models Leveraging Investments in Cultural heritage adaptive reuse), which focuses on adaptive reuse as a key strategy for CE implementation in historic cities and regions.

Contracts based on performance/function was viewed as important by contractors (3-15) but less so for other stakeholders. This was exemplified by one respondent stating 'there is a technical challenge of how a component designed 150 years ago can be envisaged to be reused'. For the event, the attendees were broadly representative of the construction industry comprising clients (5%), designers (9%), manufacturers (10%), contractors (23%), consultants (30%), government representatives (12%), and trade and professional associations (9%). x Inst. x+ | The findings enable the formulation of an overarching design centred framework to not only create, but also to develop and sustain circular value throughout the whole building life cycle, as presented in this paper.

The fragmented supply chain was viewed as a key challenge by researchers and consultants (3-32) and contractors (3-14) with a number of survey respondents criticising the lack of a holistic approach; this was also echoed in the breakout sessions along with the competitive nature of the construction industry. endobj In the Circular Economy models, the end of life building materials should be reused and their components and parts deconstructed, to act as material banks for new buildings, keeping the components and materials in a closed loop (Hopkinson et al., 2019), just as EMF proposes in the general Circular Economy concept.

A view from the tabulated responses was of the risk of changing practices, in particular the time and cost implications and how any initial cost could be offset. The survey results for the circular economy enablers are shown in Figure 3. Countries such as China and Germany have used the term within their legislation, although the emphasis can vary (Benton, 2015).
