Digester

Crows waiting for some action above the digester which has been installed in the Sainbury's car park at Kiln Lane - at least I assumed that was what it was. However, in so far as I could see inside its enclosure, just visible at the bottom left of the snap left, it appeared to be just a large white tank, the sort of thing you might use to store liquified gas in. A large label on one end saying 'SCART'

While BH thought that these trees were where the crows had always perched, in between forays into the car park for child dropped snacks. Nothing to do with the digester at all.

Reference 2 talks of a photovoltaic system at Kiln Lane, which I take to be a fancy name for solar panels on the large flat roof rather than the tank in the car park. This being a web site which does recognise digesters. But I have no idea how comprehensive or accurate its listings are.

The corporate site for Sainsbury's has a useful search feature which turns up much talk of solar, some talk of geothermal and odd snippets about biomass. But I couldn't find anything specific about Kiln Lane.

Having been defeated by google, I was reduced to phoning them up at Kiln Lane and within seconds I was being told by a rather amused young lady that underneath the white tank there was a very deep hole, a very deep hole from which geothermal energy was extracted. There is another one such at Crayford should you be truly curious. So it looks like BH was right after all.

Presumably Aldi and Lidl don't go in for any of this green nonsense. Far too careful about their costs and their bottom line for any of that - no part of their mission to look after our future, which will just have to look after itself.
