(Introduction):

Several countries implement landfills where solid waste is collected and its accumulation generates greenhouse gas emissions. This is intensified in countries where the growing population generates waste collection with organic matter compositions.

(Objective):

To estimate the emission rates of methane CH4, carbon dioxide CO2 and organic compounds other than methane NMOC in the Doña Juana landfill for the closure periods.

(Methodology):

The estimate was made using LandGEM software from the solid waste disposed of in the landfill located in Bogotá Colombia, following the years of closure established by law 2022, 2040 and 2070.

(Results):

An average of 2 152 870.48 tons/year of waste was obtained and deposited in the landfill. The estimation showed: for CH4 year of closure 2022, a maximum of 2.39E+08 m3/year and the generation would be extended until the year 2106; for 2040, a maximum of 6.10E+05 ton/year of CO2; in 2070 a maximum of 3.07E+06 m3/year of NMOC is observed and its production would end in 2142.

(Conclusions):

The energy potential in terms of CH4 that can be obtained with the years of useful life of the landfill is highlighted. Estimates of CO2 and NMOC per year show the importance of complementing solid waste disposal with optimal treatments, since they represent greenhouse gases that are emitted in large proportions.
