Franmar's claim to fame with Beeniedoo is that it breaks down plastisol into a " drain safe" liquid. We use beeniedoo for all of our screen de-inking, we don't actually flush down the drain, but into sand. Any particulate that gathers over time becomes a solid which we then roll up like a big fruit roll up and goes in the trash. That's the main reason we chose beeniedoo for our main ink-degrader, something with how their soybean oil compound interacts with the plastisol. It's awesome stuff, not caustic on your employee's skin, smells like cake batter rather than a harsh chem smell, and as soon as you scrub it in, plastisol dissipates immediately, we love it.
