Bioreactor is a modern landfills introduced in solid waste management, thus this concept are not fully universally applied yet. The objective of this bioreactor landfills involving disposal solely of inert materials after universally applied. Therefore, it is likely that landfills will continue to receive a variety of materials with potential for environmental impact. As the leachable materials are land disposed, impenetrable barriers are provided and waste stabilization is enhanced and accelerated so as to occur within the life of these barriers (Lee & Jones- Lee, 1996). That is, the landfill must be designed and operated as a bioreactor. This bioreactor landfills is equipped with liners and leachate collection systems. It operated and controlled to rapidly accelerate the biological stabilization of the land filled waste. The crucial process in bioreactor landfills is leachate recirculation, which leachate is recycled back to the landfill, to create the environment favorable to rapid microbial decomposition of the biodegradable solid waste (Lee & Jones- Lee, 1996). Additional advantages of the bioreactor landfill include increased gas production rates over a shorter duration, improved leachate quality, and more rapid landfill settlement. Instead of that, bioreactor operations protect the environment and reduce long- time liability and associated monitoring costs (Reinhart & Townsend, 1997). The rapid treatment of the waste facilitates the operation of a bioreactor landfill
