Exploring the enablers and barriers of circular economy and blockchain adoption in the construction industry

Şahin, Ufuk
Due to the take, make, and dispose of principle, which is the result of the linear economy model, massive natural resource exploitation of the construction industry (CI) results in various undesired environmental side effects. The circular economy (CE) concept emerged to alleviate negative impacts and change linear processes with circular ones. In this context, the successful use of CE in the construction industry can significantly contribute to remarkable reductions in gas emissions, massive natural resource consumption, and waste generation. Moreover, integrating digital technologies, particularly blockchain (BC), into the process is claimed to accelerate and enable CE adoption and success, while several barriers hinder such adoption. In this study, the enablers and barriers of adopting CE and BC were identified using a literature review and categorized according to the Technology-Organization-Environment (TOE) framework. Next, a survey was performed to explore the perspectives of construction-related professionals regarding the effect of each enabler and barrier on CE and BC adoption. Lack of sector awareness, BC and CE experienced stakeholders, lack of sufficient incentivization, inherent properties of CI, and difficulties in changing settled habits are revealed to be the prominent factors hindering adoption. The prominent enablers are educating sector participants, increased government incentives, and new regulations. The findings of this study can support decision-makers in planning and transforming the construction industry into a blockchain-supported circular economy.


Development of an IT-based tool for portfolio assessment and management for construction companies
Bilgin, Gözde; Dikmen Toker, İrem; Özorhon Orakçal, Beliz; Department of Civil Engineering (2019)
Development in the construction industry has leaded most of the construction companies to undertake more complex projects than before, which are generally executed concurrently. Therefore, project management routines of the companies may not support effective management of multi-projects. Project portfolio management approach has been suggested to meet requirements for coordinating multi-projects to meet strategic objectives under limited resources. Since project portfolio management requires a comprehensiv...
A Taxonomy for causes of changes in construction
Rahmani Mirshekarlou, Babak; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Department of Civil Engineering (2012)
Change is an inevitable and inherent factor of each construction project which is a result of the nature of industry and the uniqueness of projects. Risky and unstable environment of construction industry usually triggers the potential of occurring changes during a project life cycle. Effective management of changes usually leads to increasing the project success. Change prediction and evaluation is the major step of change management process which enables the project management team to have a clear perspec...
Investigating the relationship between the recent investments on construction sector and some economic indicators of Turkey
Aydın, Aykut; Özdemir, Özlem; Department of Business Administration (2016)
Construction industry is believed to constitute a significant part of the economic development and there are quite noteworthy studies that analyze the relationship between construction industry investments and economic development. This study attempts to find out this causal relationship by using Toda and Yamamoto Augmented VAR model for Granger Non-causality. In addition, two separate models are used in order to detect the effects of specific construction activities such as residential, commercial and indu...
Comparison Of Three Uncertainty-Analysis Methods To Assess Impacts On Groundwater Of Constituents Leached From Land-Disposed Waste
Ünlü, Kahraman; Chong, P.K. (Springer Science and Business Media LLC, 1995-02-01)
Assessment of the environmental fate and behavior of constituents that have the potential to leach from waste-disposal pits that are associated with petroleum exploration and production activities is a problem of interest to industry and regulatory agencies. A stochastic modeling approach for the migration of constituents in soil and groundwater was developed to assess the impact on groundwater at receptors that are downgradient from a waste pit. The model evaluates uncertainties in constituent concentrati...
Exploring the Adaptability of Daily Look-Ahead Meetings in the Construction Industry
Yılmaz, Anıl; Tokdemir, Onur Behzat (null; 2020-12-02)
Lean construction is a new approach, adapted from lean thinking, focuses an increase in productivity through control over the process to eliminate waste of project while maximizing the value offered by the project. The Last Planner System (LPS) is one of the production control and planning systems for project management in lean construction philosophy. It emphasizes reliable and optimized workflows by taking measures (Identification and resolving) for problems that may occur in advance collaboratively at th...
