I don't think that is the case Hope. A number of years ago I did an OU Science/Technology foundation course as part of a degree and we had a short project looking at waste disposal - and the conclusion that our group came to was that incineration was the best option. It requires little sorting, metals are easily extracted from mixed waste and you can reclaim a useful amount of energy.
Of course that kind of common sense approach doesn't mesh with today's Green Dogma which likes to pretend that everything really is recycled (rather than shipped off halfway round the world where no one seems to know what happens to it)

In my view, incineration is a cop out. It sees metals as the only thing that can be recycled, whereas there are many other valuable elements of waste, from glass to paper, cardboard to plastics.
The problem with incineration is that it assumes that we have plenty of raw materials with which to carry on making all these other products - sand, trees, oil, ... Yes, there are plenty of these particular examples, but not always easily available, and not always appropriate for removal in this way.
Regarding your Guardian article, I've driven along the side of one of the waste mountain they have in China. It was enormous - spreading over a massive area and tens of metres high. This is the unacceptable side of waste disposal - though quite how much of that particular mountain was Western waste and how much was Chinese waste, I'm not sure. However, that article is 12 years old, and I am also aware that more and more UK aste is being processed here in the UK - but by no means all.
Finally, I'm aware of the potential hazards that incinerator plants pose. There is a fairly new one in Cardiff, run by a company called Viridor. It was, and is still referred to as a 'recovery' plant, but there is evidence that it is burning waste. Currently, there seems to be an on-going debate as to were to dump the ash that it produces and all that that contains. There used to be an incineration plant near Merthyr Tydfil - I think that was the Valley it was in - which was closed some years ago because of the links between its emissions and childhood cancers. I appreciate that that was an old plant, and probably pretty inefficient and woth poor filtration procedures, but several others that have been built more recently have also been shown to have the same, or similar links.
