This thesisaims to analyze the impact of the circular economy on value creation within Algerian companies, using ENPC – Annexe Tlemcen as a case study. The central issue concerns how circular economy practices, particularly the 9R framework affect the company’s value creation. Our research is structured in two main parts: a theoretical section exploring the concepts of circular economy and value creation, and an empirical section based on a case study. The analysis is grounded in field observations, interviews with staff, and the examination of internal data. The findings reveal that the company implements several circular practices such as recycling Polyvinyl Chloride (PVC) and Polyethylene (PE) pipes, reusing recycled materials, and reducing waste. This contributes to creating economic, environmental and social value.frcircular economyvalue creation9R modelstrategysustainabilityThesis
