This report identifies circular economy (CE) opportunities in the tourism sector in Cabo Verde, The Gambia, and Säo Tomé & Principe. The project focuses on enhancing circularity by advocating for policy changes, phasing out single-use plastics (SUP), and promoting innovative infrastructure and sustainable financing solutions. The Cabo Verde report provides a thorough diagnostic to identify opportunities and gaps within key infrastructure systems, including materials, waste, energy, and water, tailored to Cabo Verde's unique geographic and economic context. It includes firm audits and an extensive market assessment to determine the scope and size of CE products within the tourism industry. The report also outlines the results of the Multi-Criteria Analysis (MCA) to prioritize prospective business cases for further evaluation of their financial and technical viability. Additionally, it presents an overview of the Institutional & Regulatory Analysis and Roadmap, highlighting key market opportunities such as in-vessel composting, large water dispensers, rooftop solar PV, and greywater recycling. The findings emphasize the potential for CE interventions to foster economic growth, environmental sustainability, and resilience in Cabo Verde's tourism sector.
