Landfill management

It is expected that leachate characteristics will vary by country. This is because the soil under a landfill site, the composition of disposed waste, the climate, sampling and landfill management vary among countries.7-8...

The recently adopted landfill directive (a) demands high standards of landfill management, and also seeks to ban certain difficult wastes from landfill, and (b) seeks a progressive reduction in the land-filling of biodegradable wastes which account for a high percentage of wastes sent to sites. 

Thus for waste management, and landfill disposal, the objectives are clear and apparently achievable, and in this way. Agenda 21 represents a step towards the attainment of common standards across the world, (in those aspects of landfill management that are specifically referred to), and which helps to ensure progress towards sustainable waste management. Whether or not landfill is truly sustainable is a moot point, and one which will be considered throughout this book. The concept of acceptable risk and the "nature and assimilative ctqracity of the receiving environment" are important factors in this discussion and are considered later. 

With regard to the fundamental principles of landfill management, die key difference between the two systems is that under RCRA the "dry-tomb" tqiproach is implicit, while under the proposed European Landfill Directive, "control" of infiltration is required, rather than "prevention", as under RCRA. However, the advisability of the dry-tomb approach is now being questioned within the USA (e.g. Maurer, 1993 Lee and Jones-Lee, 1993) and is discussed further in Chapter 7. 

Some common sources of trace compounds, their generation within landfill, and implications for landfill management are discussed in Gendebien et al (1992). 

Although the USEPA also acknowledge the limitations of containment systems and weaknesses in the dry-tomb approach, the requirement for the "dry-tomb" approach to landfill management remains. 

The "dry-tomb" approach, which merely transfers the responsibilities and liabilities of waste management to future generations docs not represent an appropriate way forward for landfill management.
