Análise do Metano no Setor de Resíduos Brasileiro

The report identifies the waste sector as a critical source of methane in Brazil, primarily due to the anaerobic decomposition of organic matter in landfills and open dumps. While Brazil has an ambitious regulatory framework, including the National Solid Waste Policy (PNRS) and the PLANARES plan, implementation is hindered by financial constraints, lack of technical expertise, and a failure to meet the 2024 deadline for closing open dumps. The document highlights opportunities in biomethane production, organic waste diversion (composting and anaerobic digestion), and international climate financing to help Brazil meet its NDC and Global Methane Pledge commitments.

• The waste sector is the third largest anthropogenic source of methane globally, accounting for approximately 20% of global emissions. In Brazil, methane represented 25% of total greenhouse gas (GHG) emissions in 2022, with the waste sector responsible for 15% of those methane emissions.
• Brazil generated 78.2 million tonnes of municipal solid waste (MSW) in 2023, with organic matter (food waste and gardening waste) comprising approximately 45.3% of the total. This organic fraction is the primary driver of methane emissions in the sector.
• Waste disposal remains a critical issue; approximately 26% of collected MSW is sent to inadequate sites (open dumps and non-sanitary landfills), and about 9% of generated waste is not collected at all. There are roughly 2,000 inadequate disposal sites operating across nearly all Brazilian states.
• Brazil failed to meet the 2024 deadline for the closure of open dumps under the 'Zero Dumpsites' (Lixões Zero) program, with 1,911 municipalities (34%) still relying on illegal and uncontrolled dumps.
• The National Solid Waste Plan (PLANARES) sets targets for 2040, including recovering and treating 13.5% of the organic fraction of MSW and utilizing over 60% of generated biogas, with a target installed capacity of 257 MW in landfills and 69 MW in anaerobic digestion units.
• The 'Future Fuel' Law (Lei do Combustível do Futuro, 2024) introduces a mandatory requirement starting in 2026 for the use of biomethane in the natural gas market, with annual GHG reduction targets and a compulsory inclusion rate of biomethane in distribution pipelines between 1% and 10%.
• Brazil's updated Nationally Determined Contribution (NDC) presented at COP29 targets a net GHG reduction of 59% to 67% below 2005 levels by 2035. The country also adheres to the Global Methane Pledge to reduce global methane emissions by 30% by 2030 compared to 2020 levels.
