Scott,
I used to sell landscape products going back a
couple of decades ago. One of our suppliers used
to offer a budget mulch that was partially made
from old wood pallets.
We sold this product for a couple of months but
kept finding foreign objects in it, the objects
were exactly things that you would find in
household rubbish.
I did an audit on one load and found all sorts
of nasty stuff in it and found over 40 different
types of contaminates . We stopped buying the
mulch.
If someone could explain why we found tampons
in our mulch they could probably explain why
there was asbestos in mulch recently.
Even today some of the really cheap mulches
have bits of plastic in them.
