Abstract
The sparse treatment of highly toxic leachates produced in landfills due to the
excessive generation of urban solid waste is a common problem worldwide. For this
reason, this research aims to show the convenience of the use of algal biotechnology in
leachate bioremediation processes. Nannochloris sp. species was used in this research. It
was isolated and cultured for bioassays. The leachate was diluted to 5 and 10% in the
microalgae cultures during a period of 8 d in which the growth of the species. Then
removal of nutrients (phosphate and nitrate) and the production of lipids by the
microalgae were measured. Nannochloris sp. removed more than 70% of the phosphates
and 60% of the nitrates from samples. This result shows the benefits of using these
microalgae to treat landfill leachate at low cost and also with the potential to obtain biolipids
that may be useful for biodiesel production.
