and favourable aesthetics, but they may be sensitive to the impact of differential settlement
(Pacey et al. 1996). If the leachate is planned to be recycled by direct spray irrigation onto
landfill surfaces covered with vegetation it would be beneficial to aerate the leachate prior
to recirculation. Such pre-treatment of the leachate leads to its partial mineralization which
supports vegetation growth by providing nutrients (Robinson et al. 1982).
• Adapting the mechanical strength parameters of the landfill’s base and side walls, as well
as those of the LFG collection and leachate drainage systems, to the conditions arising as
a result of the increased weight of waste. The addition of liquids to solid waste increases ...
