    What is this, I thought that landfill was a thing of the past? They leak, they pollute, they take up so much land and they waste so much energy that could be reused- I just cant believe this.

    Are there appeal processes to go through, does anyone know?

    At least burn it and get some energy back!!

    Whatever gave you the idea that landfill was finished. Even if you incinerate the waste there is toxic ash that will have to go to landfill.

    Whatever waste disposal technology you use there will always be some residue that cannot be disposed of other than through landfill. This can be for several reasons, but the most obvious ones are that incinerators, for example, leave up to 30% ash (as has already been pointed out in this thread) and that ash is of limited use for anything being heavily loaded with heavy metals and slag. The other issue is that there is always a law of diminishing returns, where the residues exist in small quantities and it is not cost effective to attempt to do anything with them.

    In any case, a properly designed and engineered landfill, particularly if used solely for process residues, is not necessarily polluting. And believe me, the degree of engineering required nowadays by the multitude of regulations, is massive and very expensive. Historically, landfills that caused problems (and Ireland is full of them) were simply holes in the ground where mixed wastes, and even septic tank emptyings, were dumped without controls. The result was methane and hydrogen sulphide leakage, and leaching of liquids to water courses. Any local authority or contractor doing that nowadays would be in very serious trouble indeed.
