As I gather from the originator this is a general P2 program question -
whether or not to promote vegetable based inks or not. The original
question led me to believe the originator was questioning the validity
of advice and/or inquiring about further research on veg. inks.

What question do you have about waste disposal? Primarily the pigments
in inks are inert materials (non-haz), unless formulated with heavy
metals to produce specific colors or metallic inks.

I have also read reports that vegetable based inks emit lower VOC's than
petroleum based. But, I thought the remaining environmental problem was
the pigment, especially in black ink. Is waste ink disposal in question
for Boulder or just emissions?
