August 21st – I had stuff to do in Aldridge on the way home, and Northgate was solid with traffic, so I cut down past the back of the Vigo landfill to hop on the canal at Brickyard Road. I noticed that the final work seems to be going on with sealing this immense refuse tip. It was capped with a top layer of marl a while ago, and landfill gas is still being abstracted and used to power a large generating set, supplying power to the national grid; but amongst the bulkheads and snaking pipes, a plastic membrane has been laid and it’s being covered in topsoil, prior to final landscaping.
The membrane prevents rainwater from getting through the cap and soaking through the refuse, where it would be extracted and disposed of as a toxic brew called leachate, which is an ongoing, expensive operation.
Reducing leachate production also lowers the future chances of groundwater pollution.
Landfill is quite a high-tech operation these days, if carried out properly.
