As COP26 redoubles efforts against the gas, a new plant tackles plume visible from space
Trucks arrive at the brown hill like an army of ants, then crawl up, whipping dust into the sky before dumping trash unceremoniously at the top. What happens later sets the Buenos Aires landfill apart from most others in South America: Planet-warming methane leaking from the trash is turned into power, Bloomberg News reports.
Norte III — a 1,200-acre site whose garbage hills draw the eye in table-flat Buenos Aires — recently activated a new power station that runs on gas piped from under the hill through tree-trunk-sized black tubes. The five megawatts generated by landfill operator Ceamse may be enough to run only several thousand homes, but they represent a victory in a global campaign against methane that’s gathering momentum at the United Nations climate summit in Scotland.
Methane rising from the hill known as module D became a global hot spot, with rotting food creating a plume so dense that it could be seen from space, according to a June image from geoanalytics firm GHGSat.
