Authorities Monday shut down Mexico's -- and possibly the world's -- biggest garbage dump and said they would invite bids to exploit methane gas generated by the decomposing waste.

Waste Management Commission chief Fernando Menendez called the closing "historic" as "it is the world's largest (truck-filled open-air) dump."

The Bordo Poniente dump for years saw 200-250 trucks a day cast off their waste -- up to 6,000 tons a day at its peak. Dumping had slid recently to some 2,800 tons a day, as it neared capacity.

Mayor Marcelo Ebrard was on hand for closing day, and insisted that using the offset was key.

The dump, thought to hold millions of tons of compressed waste, towers over 17 meters high.
