The message
from "Franz Heymann" contains these words:

Nothing survives an well executed composting process My Council
jollop looks as near to perfectly composted material as I have ever
seen. Time will tell if it only looks good, or if it actually
benefits the garden.

In rec.gardens archive in google, you should be able to find the
threads about their equivalent of council compost containing high levels
of plant-toxic chemicals. These were supposed to have arrived on
clippings from treated lawns.
