I have on occasion disposed of banana skins in the undergrowth of a hedge or woodland (out of sight) when on country walks locally in Sussex, and given banana skins decay rapidly in that climate and the countryside in Sussex is heavily altered by human activity, I don't see the problem there.
Apparently it still takes up 2 years to biodegrade. Don't be part of the problem, leave no trace every time!
