Waste Management in Brazil

The video discusses waste management in Brazil, highlighting that only 32.3% of municipalities have selective collection programs. Despite this, Brazil leads in aluminum can recycling. Waste can be disposed of in open dumps, controlled landfills, or sanitary landfills, each with different environmental impacts. Open dumps cause pollution and health risks, while sanitary landfills use impermeable layers and drainage systems to manage leachate. Incineration is used for hospital waste to prevent contamination. Recycling involves sorting inorganic waste for industrial reuse, and composting processes organic waste into fertilizer and methane gas.
