Mexico City (DF) mayor Marcelo Ebrard has confirmed the closure of the Bordo Poniente sanitary landfill.
The landfill, one of the world's largest, has closed ahead of the December 31 deadline under an agreement reached last year between the federal and DF governments, according to a release.
Closure of the site, estimated to cost between 800mn (US$58.1mn) and 1bn pesos, will reduce CO2 levels by 2Mt/y, the release said.
The DF government plans to publish a 25-year concession tender for the extraction, capture and use of biogas at the site for electricity generation in the coming days.
Prior to the scaling down of operations earlier this year, some 12,600t of garbage were delivered to the site each day.
