Garbage disposals are dirty,nasty, stinky,and loud. We know these things to be true. They also are handy and versatile. Keep it fresh by grinding lemon peels. keep it fresh by grinding a mix of baking soda with ice-cubes. Save the nasty stuff like potato peels and coffee grounds for use in the compost heap. Remember to grind the good smelling stuff last and use plenty of water to flush it away. Todays disposers are made to be quieter than granpas old bonecrusher you just shouldn't be crushing bones in it cause it doesn't have the power to do it effectively. I don't know what the disclaimer language on a modern disposal units packaging says but I'll bet it advises against using it to dispose of the usual things one normally does.
