The Choosing of a Landfill Site There is currently much debate on the desirability of landfilling particular wastes, the practicability of alternatives such as waste minimisation or pre- treatment, the extent of waste pre-treatment required, and of the most appropriate landfilling strategies for the final residues. This debate is likely to stimulate significant developments in landfilling methods during the next decade. Current and proposed landfill techniques are described in this information sheet. Types of landfill Landfill techniques are dependent upon both the type of waste and the landfill management strategy. A commonly used classification of landfills, according to waste type only, is described below, together with a classification according to landfill strategy. The EU Draft Landfill Directive recognises three main types of landfill: Hazardous waste landfill Municipal waste landfill Inert waste landfill Similar categories are used in many other parts of the world. In practice, these categories are not clear-cut. The Draft Directive recognises variants, such as mono-disposal - where only a single waste type (which may or may not be hazardous) is deposited - and joint-disposal - where municipal and hazardous wastes may be co-deposited in order to gain benefit from municipal waste decomposition processes. The landfilling of hazardous wastes is a contentious issue and one on which there is not international consensus. Further complications arise from the difficulty of classifying wastes accurately, particularly the distinction between 'hazardous'/'non-hazardous' and of ensuring that 'inert' wastes are genuinely inert. In practice, many wastes described as 'inert' undergo degradation reactions similar to those of municipal solid waste (MSW), albeit at lower rates, with consequent environmental risks from gas and leachate. Alternatively, landfills can be categorised according to their management strategy. Four distinct strategies have evolved for the management of landfills (Hjelmar et al, 1995), their selection being dependent upon attitudes, economic factors, and geographical location, as well as the nature of the wastes. They are Total containment; Containment and collection of leachate; Controlled contaminant release and Unrestricted contaminant release. A) Total containment All movement of water into or out of the landfill is prevented. The wastes and hence their pollution potential will rem... This is not the end of the termpaper!
