The paper investigates reusable packaging business models for fast-moving consumer goods (FMCGs) to address global environmental challenges caused by their disposable nature. It focuses on identifying success factors, drivers, and barriers in a circular business model pursued by a company operating in both in-store and e-commerce contexts. Through interviews and a consumer survey in Berlin, the study highlights five success factors, including partnerships, operations efficiency, and consumer participation. Environmental concerns motivate consumers, while logistics and costs are major barriers. Recommendations for scaling these models are provided based on the findings.
