BTW, do you also recall any use of cars that had processed charcoal in them,
or was this just this individual's memory of the coal usage that prompted
that?



Elden:

Processed charcoal is a component of the filters in water treatment plants.
It is used to absorb organic compounds in the water as part of the treatment
process. Filter beds are layered with sand and activated charcoal. The
charcoal needs to be changed infrequently. But a large plant with many filter
beds would have a need for an occasional charcoal shipment in covered hoppers.
