After the end of the Carnival festivities in Rio Branco, approximately 120 tons of waste were collected, prompting concerns about environmental impacts linked to waste disposal. In the adjacent city of Cruzeiro do Sul, which is the second-largest in Acre, over 60 tons of waste were also reported. This significant increase in waste during Carnival highlights the challenges faced by local authorities in managing post-festival waste, which not only poses a threat to the local environment but also affects the quality of air and water in the region.

Edson Guilherme, a professor at the Federal University of Acre and coordinator of the Recicla Ufac project, discussed the consequences of the waste generated during these celebrations. He pointed out how improper waste disposal can lead to pollution in water sources from which the community draws drinking water, as well as contributing to atmospheric pollution through the release of harmful gases. These emissions can exacerbate existing environmental issues and pose health risks to local residents.

The report emphasizes the need for more effective waste management strategies during high-traffic periods such as Carnival. It raises awareness not just about the quantities of waste produced but also about its long-term implications for local ecosystems. Sustainable practices and better recycling initiatives are essential to mitigate the adverse effects of festival-related waste and ensure the protection of both air and water quality in Acre's cities.
