Can I put prickly pear skin in the disposer?

How it behaves in the disposer

Prickly pear skin looks harmless, but in the drain it behaves differently. It would never reach fine particles in the chamber: it would sit in the trap, or further along where the pipe narrows. The very fine spines stay in the sink and on your hands: wrap the skin in paper and put it in the food waste bin. The fine spines stay in the sink: it goes in the food waste bin. The right route is the food waste bin, with the rest of the kitchen scraps.
