Abstract:

PurposeDespite the positive impacts of the construction sector on enhancing economic growth and ensuring societal well-being, its negative impacts on the environment from unsustainable resource consumption levels, emission of greenhouse gases (GHGs) and waste generation is monumental. Circular economy (CE) concept is identified globally as an avenue to address problems regarding adverse impacts of construction on the environment. This paper presents the principles of CE as an avenue for enhancing environmental sustainability during the pre-construction stage within Sri Lankan construction projects.Design/methodology/approachThis research was approached through a qualitative research method. Data were collected through semi-structured interviews with subject matter experts. The number of experts were limited due to lack of experts with knowledge on the subject area in Sri Lanka. Data were analysed using content analysis.FindingsFindings revealed a range of activities under each R principle of CE, that is, reduce, reuse, recycle, redesign, reclassification and renewability that could be implemented during the pre-construction stage, thereby providing a guide for construction professionals in implementing CE at the pre-construction stage. The need to expand knowledge on CE concepts within the Sri Lankan construction sector was recognized.Originality/valueThis study provides a qualitative in-depth perspective on how 6R principles of CE could be integrated to a construction project during the pre-construction stage. By adopting the proposed activities under CE principles, construction professionals can enhance the environmental sustainability of construction projects.
