Under the point system for collection of recovered paper "Town ecomo," special collection boxes are installed in supermarkets and other places for customers to deposit recovered paper in exchange for points that are given according to the weight. These points are exchanged for gift certificates at supermarkets when customers earn the required points. The supermarkets motivate customers to visit them again and can advertise their ecological contributions. Customers can dispose of recovered paper anytime by visiting a store and can earn points.
