As landfills become more sophisticated and take on the role of massive waste to energy
bioreactors (methanogenic digesters), the demand for odour management will become more
critical. The principles which need to be adopted are to minimize the number of sources of
odour generation which exist on site; undertake direct management of those sources which
can give rise to problems; ensure natural attenuation is available for those emanations which
cannot be directly managed. The mitigation of odour can be achieved by the followings:
