I suspect that what would be even more useful than a Touchless Trashcan, would be Touchless Trash. However I could be wrong. $99.95.
‘The Touchless Trashcan uses patented invisible harmless infrared technology. Place hand or debris about 6 inches away from the infrared sensor near the lid. It will open instantly when you approach and will close automatically in 3-second after debris has been released and hand moves away.’
