i dont generally bring apples and bananas or things that have inedible portions to them on my rides, my gel packets obviously go straight in the back of my jersey once done, but for those that do bring bananas oranges apples and the sort, you're actually doing the environment more harm by throwing that stuff away in a trash bin. By throwing stuff in a plastic bag that gets closed up prevents decomposition and takes up more space in a land fill. By throwing your decomposable stuff in plastic bags youre effectively taking nutrients out of the natural cycle and harming the earth more. Technically paper is decomposable but dont just throw that stuff on the ground, shred it and send it to a recycling facility, obviously dont throw out or litter with plastics or glass, recycle that stuff. if by "properly dispose of" you meant compost your peals, then yes... but its the same thing when thrown in the woods... just dont throw it in an obvious place... burry it in a moist area whenever possible.
