Abstract

In landfill, the control of degradable organics and related environmental impacts may be achieved by means of a series of options, including avoidance of putrescible fraction in landfilled waste (separate collection), prestabilization of waste prior to landfilling, in situ treatment to enhance biodegradation during landfilling and/or the aftercare phase, combinations, etc. Landfills that are purpose-designed and operated for the in situ treatment of degradable waste with the aim of enhancing conversion processes are known as landfill bioreactors. Possible in situ measures include leachate recirculation, introduction of water, natural or forced aeration, pH control, etc. Improved control of biochemical kinetics, moisture content, and redox conditions may result in a significant shortening of the aftercare phase and consequently, environmentally sustainable targets may be reached in a shorter time. According to biodegradation conditions, landfill bioreactors can be subdivided into four m...
