This thesis investigates how the Grondstoffenstation, a Circular Community Initiative in the Afrikaanderwijk in Rotterdam, creates multiple forms of value and how this value creation can be structurally supported by policy and governance frameworks. The study uses a Participatory Action Research approach and participatory observation, interviews, content analysis, and a focus group as it methods. It was explored which ecological, social, cultural, aesthetic, and financial values are contributed by the GSS to the Afrikaanderwijk. Through the Circular Value Flower (CVF) framework, these values are mapped across stakeholder groups, highlighting diverse perspectives and practices based in co-operation. The research demonstrates that while some values can be meaningfully quantified, others are best conveyed through qualitative narratives. The findings show that structural and bureaucratic barriers hinder long-term collaboration between initiatives and public institutions, despite alignment in objectives. The thesis concludes that initiatives like the GSS should be regarded not merely as temporary projects, but as public service providers and as agents for public value contestation. Recognising their broader societal impact requires more inclusive, long-term, and value-driven policy approaches.
