Although some waste products may be used through recycling, reuse or composting, per capita production along with poor culture in solid-waste management is beyond the capacity of waste reuse. Landfills are the most commonly used method for controlled management of municipal solid wastes (Renou et al., 2008; * Corresponding author.

Chemical reactions -proper of biological activity- take place there, producing gases and leachate due to the moisture content of the residues (mainly the organic ones), compaction and water that inevitably pours into landfill. According to the Mexican Standard NOM-083SEMARNAT-2003 (SEMARNAT, 2004), a leachate is a liquid formed by the reaction, drain or filtering of materials constituting the residues. It may contain, either dissolved or suspended, substances that can infiltrate onto soils or drain from the sites where the residues are deposited. This can lead to contamination of soil and water bodies, causing their deterioration and posing a potential threat to human health and other living organisms. The leachate composition can vary considerably from one place to another, and even within the same site along the year (Yokoyama et al., 2009). Depending on the landfill’s age and composition, leachates are classified in young, medium-age or stabilized. Biological treatment processes (aerobic or anaerobic) are very effective on first-stage leachates of high biodegradability index (BI) (Calli et al., 2005). However, they generally fail when the leachate’s BI is low or when there are high concentrations of toxic metals (Deng and Englehardt, 2006). In addition to large amounts of organic matter, the possible presence of heavy metals and high concen (...truncated)
