May 2nd – Heading off the canal at Leighswood Bridge there’s a footpath that somehow, against huge odds, has managed to stay open despite wending a precarious way between Europe’s largest inland toxic waste facility and an immense marlpit.
The red marls that have been opencast here for centuries made the area of Aldridge and Stubbers Green famous for it’s brickworks and tileries, producing high-quality engineering bricks and building materials that an entire industrial revolution was built out of.
These days, marl is excavated in an almost robotic process. An excavator works down the face in terraces, and four huge trucks are filled in a constant relay, each carrying three excavator bucketfuls to the Wienerberger brickworks up top. At the base of the excavation, there’s a pool of drainage water. This is returned to a settling lagoon on the surface by a pump, floating on a raft, cleverly made out of empty drums. Note that the marl itself is quite dry, and not the clay-like material one would expect. Impervious to water, it makes an ideal void into which landfill of most grades can be dumped when the opencast is exhausted. This area is surrounded by landfill sites utilising former marl pits, and under it all, millions upon millions of gallons of toxic slurry dumped in the deep coal workings that also riddled the landscape.
There’s nothing so valuable as a hole in the ground.
In many countries, this would be considered environmental destruction. Here in the UK, we call it industry.
