Hybrid bioreactor landfill

In addition to accelerated waste decomposition, the other important advantage of hybrid bioreactor landfill technology is the high efficiency of nitrogen removal from the leachate. Oxy-

The aerobic-anaerobic bioreactor landfill technology is not widespread in the world. It was applied in the field scale in North America at the Metro Recycling/Disposal landfill in Wisconsin (Kidman et al. 2011).

Hybrid (aerobic-anaerobic). The hybrid bioreactor landfill accelerates waste degradation by employing a sequential aerobic-anaerobic treatment to rapidly degrade organics in the upper sections of the landfill and collect gas from lower sections. Operation as a hybrid results in an earlier onset of methanogenesis compared to aerobic landfills.
