The way we handled dishware, cups and utensils while camping is that everyone has their own set. You lick them clean and polish, if you please, with your bandanna. Everyone has three bandannas minimum. That eliminated the paper plates, disposable plastic utensils, napkins and paper towels.

We never stopped using toilet paper but a Roman 'swabium', a communal hand mop used to clean the backside that is boiled out with wood ash, is an option. Newsprint or other paper can be allowed to weather to soften it. If water is available a water rinse and drip-dry is an option.
