Honestly this sounds weird but have you considered a couple of things to make the tasks less steps?

Small trash cans with no lids. (Small forces it to be taken out regularly, no lids means fewer steps to the task)

Have a couple of laundry baskets, also no lids. If she knows that she won’t reliably go to the bathroom and put it in that hamper, then have a couple of hampers in the house. She’ll be much more likely to put things in the basket if it’s right there than she would if it was two rooms down.
