How come the toilet doesn't have a built in garbage disposal?

[JVS]

I got a bag of apples on the cheap the other day, and a few of them aren't good, and even the ones that are good have cores.
It sure would be convenient to be able to flush them.

1. It would clog the sewer lines dumbass

Waste from toilets uses pipes that are completely separate from the pipes that sinks use

2. More to the point, why can't you flush a garbage disposal?

Without getting into specifics, I think it would save a lot of time.

4. Toilets on airplanes have always remind me of garbage disposals, with all the racket they make

5. The added expense of such a feature

might be more than the cost of a simple toilet and an ordinary disposal unit. Plus, it's probably a hundred times more convenient to have such a thing in the kitchen.

I guess you could skip the toilet altogether and just place a toilet seat over the kitchen sink.
