A massive landfill in Argentina is reportedly the largest in Latin America. The Complejo Ambiental Norte III, located near Buenos Aires, spans 500 hectares and receives a significant portion of the country's waste. The landfill is said to receive around 436,000 tons of waste each month.

A study by the University of California in Los Angeles has also identified it as a major emitter of methane, a gas contributing to global warming and climate change. Further details on the landfill and the controversy surrounding the study's findings are available from the source, including reactions from scientists and local operators who question the methodology used.
