Development of Waste Management in the Last 30 Years
Landfilling often is not regarded as a technically and operationally highly demanding waste management option as e.g.incineration.In many cases landfills are seen as a cheap way to get rid of the waste.Mistakes in the design and operation often may become relevant after many years or decades and remediation will be in general become very costly.Siting,lining and drainage are key factors for the long-term functionality of a landfill.It always has to be kept in mind that these systems have to be operational “for ever.Landfills have to be operated in a way that the biologically degradable waste is degraded in a relatively short time(few decades after landfill closure); by these means the emission potential will be significantly reduced.Measures to reduce the aftercare phase are mechanical-biological pre-treatment and in-situ aeration.Important part of landfill operation is aftercare and release of a landfill from aftercare.Under which conditions can a landfill be released and does that mean that then no more care will be necessary? Open questions are also how to deal with high water levels and temperatures in landfills.Another important issue is the question how the bottom drainage system can be kept functional over long periods of time(avoid clogging and collapsing of drain pipes)and in case of damage how they can be repaired or substituted.
