G'day Steven,
My direct reply would be that AD adds NOTHING (as in chemicals) to the
waste, so the arsenic is in the manure (or water!)! Thus AD may well be
beneficial in that it is likely to reduce the amount of arsenic (or any
other heavy metals/pollutants) reaching the waterways as it may bind them or
at least let them be applied to land!
Happy digesting,
HOOROO

Hi Group,
I overheard one of our more local strident activists, when asked about
AD for poultry comment that the by-product compost from poultry
digesters contained significant amounts of arsenic.
Can anyone comment on this or other known or potential anti-AD
Environmentalist issues. Here on the "Delmarva" peninsula
over-application of raw chicken manure onto the farm fields, and the
subsequent runoff into our abundance of estuaries and bays is a big
issue. Our goal of introducing absolute containment with solar heated
bladder/ batch systems and a more environmentally acceptable compost
byproduct .... is supposed to attract a positive response from activists.
Comments, Information, Suggestions?
Thanks!
Steven
