The event will present the experience of CETRO-BV (Composting Center of Boa Vista), a pioneering initiative in the Brazilian Legal Amazon that transforms urban organic waste into high-quality compost, preventing its disposal in landfills and reducing greenhouse gas emissions. The project promotes circular economy, urban resilience, and climate adaptation, while also fostering social inclusion and income generation for Venezuelan migrants and Indigenous communities in vulnerable situations. The CETRO-BV experience demonstrates that innovative environmental solutions can be effectively implemented through coordinated action between local governments, civil society, and the private sector, offering practical and replicable responses to the challenges of urbanization, food security, and climate change in Brazilian cities.
