Methane Menace: The World's Landfill Giant Confronts Climate Change

A landfill near Santiago, Chile, has been identified as a major source of methane emissions, according to a UN study. Dubbed Lomas Los Colorados, the site tops the list of global methane emitters, raising alarm about its impact on climate change beyond regional borders.

Despite environmental concerns, the landfill also serves a dual purpose. Since 2007, it has been capturing methane to generate biogas, which powers a local power station. This process offers a cleaner energy solution, helping to reduce greenhouse emissions equivalent to nearly 2 million cars annually.

Calls for improved waste management are growing. Experts emphasize the need for systems that better separate and process organic waste, potentially through anaerobic digestion or composting, to minimize bad odors and environmental impact.
