Sustainability has long been an issue of concern to society, countries, and the economy. In this context, circular supply chain management is an advantageous strategy for minimising material consumption, waste, and carbon emissions while generating recycling possibilities throughout the supply chain. To ensure the successful integration of circular supply chain practices by Small and Medium Enterprises (SMEs) businesses, it is imperative to investigate the key barriers and main enablers that can drive its successful adoption. The scoping review methodology, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR), was used to analyse 188 selected publications. Five interrelated important entities, which are government agencies, industry stakeholders, SME management, customers and funding agencies were recognised as essential players in the effective execution of circular supply chain activities. The circular supply chain framework is envisaged to motivate the policymakers to adopt the suggested framework by increasing supporting legislative measures and implementing practical promotion and education strategies to promote its adoption.
