“…This pipe should be bedded in drainage rock and at least two-thirds of the pipe diameter should remain open to provide for passive air inflow to the bottom of the landfill. Deep aeration was observed in lysimeter experiments to provide the quickest degradation of organic carbon as well as enhanced nitrification compared to injection of air at shallower waste depths (Wu et al 2014). Figure 14.11a illustrates air entry into the semi-aerobic bioreactor from the LCRS.…”

“…This simple change produced a difference of 22% in settlement. The authors suggested doing more research into aeration rates which has been done by Slezak et al [35] and extended to where in the waste mass the air should be injected by Wu et al [36].…”

This review aims at the treatment of the entire landfill, including the waste mass and the harmful emissions: leachate and landfill gas. Different landfill treatments (aerobic, anaerobic and semi-aerobic bioreactor landfills, dry-tomb landfills), leachate treatments (anaerobic and aerobic treatments, anammox, adsorption, chemical oxidation, coagulation/flocculation and membrane processes) and landfill gas treatments (flaring, adsorption, absorption, permeation and cryogenic treatments) are reviewed. Available information and the gaps present in current knowledge is summarized. The most significant areas to expand are landfill waste treatments, which in recent years has begun to grow but there is an opportunity for much more. Another area to explore is the treatment of landfill gas, a very large field to which not much effort has been put forth. This review is to compare different treatment methods and give direction to future research.

“…N 2 O is produced mainly through microbial processes, as a byproduct of nitrification and an intermediate product of denitrification (Ruser et al, 2006). Ammonium, a long-term pollutant in a traditional anaerobic landfill, can be dramatically reduced in an aerobic landfill because the introduced air can provide a favorable environment for simultaneous nitrification and denitrification (Ritzkowski et al, 2006;Wu et al, 2013). Recently, N 2 O emissions from aerobic landfill have begun to attract a great deal of attention globally because while landfill aeration induces nitrogen removal, it also promotes N 2 O production process (Powell et al, 2006;He et al, 2011).…”

“…The aerobic-anaerobic landfill method (AALM) is considered to be a novel landfill method, which simultaneously incorporates the advantages of an aerobic-type landfill and reduces operational costs (Wu et al, 2013). According the principle of AALM, a transient zone is created between aerobic and anaerobic zones.…”
