Estimates of methane emissions and comparison with gas mass burned in CDM action in a large landfill in Eastern Amazon.

This work studied the methane gas production of the Aura landfill, the official destination of all Municipal Solid Waste of the Metropolitan Region of Belem (Brazil), operational until 2015. In 2007, the Aura Landfill was equipped with a landfill gas burning system in a CDM/UNFCCC project, with reported measured volumes of burned methane gas. These volumes were used to retrieve the methane generation potential (L) and the decay rate (k) parameters of single-phase, first order landfill emission model, yielding L=(61.
