Mexico's federal district (DF) public works department has launched a tender to clean up the city's Bordo Poniente sanitary landfill and carry out waste-to-energy operations at the site.
The awardee will be responsible for cleaning up the landfill and using biogas from the estimated 72Mt of waste held there for fuel or electricity generation under a 25-year concession, according to information published in the city's official gazette.
A waste-to-energy plant at the site would have capacity of between 40MW and 70MW, city public works head Fernando Aboitiz told BNamericas previously. Authorities aim to use power generated at the landfill to run the city's metro system.
The eventual operator will have to register the project as a clean development mechanism (CDM) so it can generate carbon credits.
Bidding rules will be available for purchase from March 29 to April 4, with a site visit scheduled for April 11. The works department aims to open bids on July 3 and award the concession contract on July 31, according to the schedule.
The Bordo Poniente landfill, one of the world's largest, closed in December last year under an agreement reached between the federal and DF governments.
