Ecuadorian Waste Sector Methane Analysis

Ecuador's waste sector accounts for 18% of the country's annual methane emissions, with a significant portion concentrated in the cities of Guayaquil and Quito. While the government has established a legal framework promoting the waste hierarchy and inclusive circular economy, implementation is hindered by a lack of long-term planning, insufficient funding for infrastructure, and poor data quality. Current mitigation efforts are limited to landfill gas capture in the three largest disposal sites, while organic waste treatment remains largely decentralized and under-prioritized. The report recommends developing a national integrated solid waste management plan with specific methane targets and improving waste tariff systems to ensure financial sustainability.

• The waste sector is a major source of methane in Ecuador, representing 18% of the country's annual methane emissions, and on average 92% of all greenhouse gas emissions from the waste sector are methane.
• Methane emissions are highly concentrated in urban centers; 15 municipal solid waste disposal sites account for 64% of total emissions, with Guayaquil and Quito alone responsible for 42%.
• Ecuador's waste generation is increasing rapidly, growing from over 5 million metric tons in 2022 to a projected 15 million metric tons by 2030.
• Landfill gas capture is only practiced at the three largest disposal sites: Pichacay in Cuenca, Las Iguanas in Guayaquil, and Inga in Quito. Active capture and flaring are not legally required; only passive venting is mandated by the Ministry of Environment, Water and Ecological Transition (MAATE).
• Organic waste, which makes up approximately 70% of Ecuador's waste composition, is under-prioritized. While composting is common for market waste in 51 municipalities, anaerobic digesters are not used in the country.
• Financial sustainability is a critical barrier, as only 40% to 60% of waste management costs are recovered through tariffs, and many municipalities do not conduct the necessary studies to set accurate rates.
• The informal recycling sector is highly productive, with approximately 20,000 recyclers recovering up to 208,000 tons of inorganic waste annually, yet they rarely receive financial compensation from municipalities.
• Data quality and availability are poor, with municipal data often estimated rather than measured. There is a lack of harmonized information between the National Institute of Statistics and Census (INEC) and MAATE's GRECI project.
• Ecuador's long-term climate goals include a National Climate Change Mitigation Plan 2024⁰, which targets a 50% decrease in total GHG emissions by 2070 and the elimination of 100% of open dumps by that date.
• The regulatory environment is characterized by a lack of enforcement of the waste hierarchy and a lack of long-term planning, often resulting in the use of 'emergency cells' when landfills reach capacity prematurely.
