Last Tuesday, I went to the landfill facility that West London Waste uses in Calvert in Buckinghamshire. The science of these places is more sophisticated than you might think, with careful monitoring of possible effluents, the use of reverse osmosis to sterlise the leachate from the buried rubbish, and the harvesting of methane for electricity generation.
However, I was also told that some of the people who live on a new housing estate just by the landfill facility bought their houses without realising that they were near a landfill. Apparently, some people allow the property developer to handle all the administratio, including land searches, when buying a house. Extraordinary.
