Unlocking circular economy potential: knowledge requirements of design teams in Australian construction and demolition waste management

Purpose The Circular Economy (CE) knowledge of design professionals plays a critical role in the effective management of Construction and Demolition (C&D) waste, yet it remains insufficiently explored in the current literature. Accordingly, this study aims to identify the key information, skills and values that support design teams in implementing CE principles to manage C&D waste during the design stage of construction projects. Design/methodology/approach Nineteen semi-structured interviews were conducted with CE design professionals within the Australian construction industry. The qualitative data collected were analysed using reflexive thematic analysis. Findings The findings are synthesised into a three-layered knowledge framework, conceptualised as a “knowledge wheel,” comprising values (core layer), information (middle layer) and skills (outer layer). Twenty values influencing CE adoption by design teams were identified across six categories: financial, environmental, operational efficiency, commercial, social and moral. Eight categories of information: regulatory, project-specific, applicable CE concepts, stakeholder participation, tools and technologies, design methods, material and waste encompass 49 distinct information requirements. Additionally, 23 required skills were classified under analytical, design, communication and managerial domains. Practical implications By framing CE through design-stage knowledge requirements, this study contributes to Sustainable Development Goals (SDGs) 4, 8, 12 and 13, advancing education, green economic growth, sustainable production and climate action, respectively. Originality/value This study offers the first in-depth investigation into the specific knowledge requirements for design team professionals to implement CE principles for the effective management of C&D waste in construction projects.
