For those that do wear disposable gloves to dump, please properly dispose of them when you're done. Toss them in your trash can (or the nearest bio-hazard bin if you think it appropriate). Don't toss them on the ground or rinse them into the park's sewer. They won't cause anything but problems there.
If you're wearing them to keep from getting dirty then any old waste bin will work. If you're wearing them for fear of biohazard they should be placed in proper red biohazard containers. Otherwise, you're just spreading the possibly infectious material around.
