Abstract
There is a growing need for construction projects to upgrade and create new infrastructures, not only in developing but also in developed countries. During this development process, substantial amount of natural resources are being used. But such developments does not come cheap. During this process, significant amount of material waste is produced. Therefore, circular economy culture is inevitable to avoid the depletion of natural resources. But the culture of circular economy is yet to develop in construction industry. In order to dig out the barriers in circular economy and its enablers, a comprehensive literature review was conducted. After going through a filtering process, around fifty (50) different research papers are consulted. Major barriers identified through literature include non-availability of environmental bylaws, governmental preferences, lack of recycling materials market and worker’s behaviour in waste control. Further, major strategies to promote circular economy are development of business models for wasted materials, formulation of bylaws to implement waste control strategies on construction sites, financial support from governments in the form of subsidize. In the end, usage of latest tools such as building information modelling, radio frequency identification and global positioning system for different waste control processes are described.
