It has been observed that some people tend to discard their food remains in public places, such as in parks, on the subway, at scenic spots and in other places. This results in an unpleasant environment as well as waste pollution. To alleviate this social problem, Tissue with Sack is designed as a new kind of disposable napkin with a carrying bag. After food consumption, a napkin may be taken out for cleaning purposes. The same napkin can be converted into a bag to hold the rest of the food waste before disposing the entire bag into a garbage can. This is an easy and clever design that targets the problem.
