The garbage is disposed in a dump in the open air, is the most common way to eliminate municipal solid waste
in Mexico, such is the case of the former ex drump called “Bordo Xochiaca” which has received more than
1,200 ton of municipal solid waste from Mexico city, who has operated since 1975, but in 2006 was definitely closed
and sanitized, today this site is a mall and sport center. With 13 years elapsed with its closure and following the
protocols of Mexican standar continue to generate a significant amount of leachate. A focus on the treatment of
leachates is to make use of the municipal solid waste that was extracted from the final disposal sites with more than
eight years buried, this waste is called “stabilized material” and is used as packaging material in bioreactors that
present important efficiencies in COD and BOD removal. This is why the present work proposes to make use of the
recirculation of a leachate from the closed disposal site and inoculate it with rumen of cow origin, in a bioreactor
packed with stabilized material from the same site, which will operate in anaerobic conditions, which will allow
decrease stabilization times in a final disposal site to accelerate the release of biogas due to the proximity to crowded
places. The high efficiencies in bioreactors are attributed to the existence of microbial communities in the stabilized
material that have been acclimated to high concentrations of contaminants, developing a capacity to degrade organic
matter. This treatment will allow leachates to be used for internal uses in the final disposal sites, converting it from
a contaminating liquid to a potential resource, in addition to avoiding such liquids may infiltrate in the basement or
in the bodies of surface water drainage.
