Could you do it pneumaticly?
You might do better in materials handling or like forum.

Even better, don't take the word of a random idiot on the Internet; talk to a pump manufacturer, supply them some samples of your plastic bits, and ask them to recommend a closed impeller large enough to pass your stuff, or an open impeller, a paper stock impeller, or even a trash pump impeller. Pumping bits of plastic in water is not new technology.

Question: how do you ensure the plastic floating on top ends up in the pump inlet?

Your suggestion has merit, the problem will be finding the best submergence so as to entrain the plastic while not entraining excessive air putting the pump off prime.

A floating pump with one of the impellers which Mike suggested should work.Thanks a ton.

What is the output of your grinder? Is it already in water? Dry?
A water ejector pump might work for you:

- feed plastic to tank bottom with long auger
- feed plastic to tank top, and mix
Or have a small tank with a mixer, you submerge the plastic bits by mixing and pump from there.

Some sort of paddle mixer or agitator would seem to be a good idea
