Ficha informativa sobre a análise do metano no setor de resíduos do Brasil

The document outlines the state of methane emissions in Brazil's waste sector, identifying that 15% of national methane emissions in 2022 came from waste, with 68% of those originating from solid waste disposal. It details the institutional framework, current waste management statistics, and key challenges such as low recycling rates and the persistence of open dumps, while recommending improvements in organic waste treatment, landfill gas recovery, and regulatory enforcement.

• In 2022, the waste sector—comprising municipal solid waste and wastewater—accounted for 15% of Brazil's total annual methane emissions, and approximately 97% of all greenhouse gas emissions from the waste sector were methane.
• Solid waste disposal, including managed landfills, unmanaged landfills, and open dumps, is the primary source of methane in the sector, contributing approximately 68% of its total emissions.
• Brazil's waste management infrastructure faces significant gaps: while 91% of the population has access to collection services, only 36% have access to selective collection, and only 4% of waste is recovered for recycling and treatment.
• The final destination of collected municipal solid waste is dominated by landfills (70%), while 26% go to open dumps or uncontrolled landfills, and 9% of generated waste is not collected at all.
• Brazil has established several legal frameworks to manage waste and mitigate methane, including the National Solid Waste Policy (Law 12.305/2010), the Basic Sanitation Legal Framework (Law 14.026/2020), and programs such as Lixão Zero and Metano Zero.
• Key barriers to methane reduction include a fragmented management approach, lack of data, financial constraints, and limited infrastructure for organic waste treatment, such as composting and anaerobic digestion plants.
