We use a lot of cardboard for sheet composting so I just posted this very
question to the compost listserv and the answer was mixed. Some were adamantly
opposed to using cardboard in compost because of --as of yet
unverified--information about heavy metals in the inks. Others were more
moderate in their opinions citing the fact that Rodale and others have used
cardboard in their compost without deleterious effect. Basically, the jury is
still out pending further science (which would be great if anyone would like
to volunteer some either way). However the general consensus was that it would
be best if paper was recycled back into paper rather than used on the land.
Thoughts?
