Printech Archive, July, 1999: Paper Recycling with Water-Based and Soy Inks

Paper Recycling with Water-Based and Soy Inks

We received a request for information on difficulties faced when recycling
paper that contains water-based or soy inks. In particular, it has been
said that conventional methods for removing solvent-based inks from process
water are ineffective for removing water-based inks.
Does anyone have any information that confirms or refutes this? Any
related information would be appreciated, as well. I am searching the
question myself and will post anything I come up with. Thanks.
