free idea #1
weight- or volume-based trash collection
users pay a per-pound fee for landfill use and receive per-pound refunds for recyclable materials. deffenbaugh industries (local trash hauler) already has mechanical arms that pick up containers. these could be outfitted with a weight sensor of some sort that electronically updates your account each week, resulting in a dynamic balance for each pay period. per-pound fees could be calculated based on research of average amount of trash disposed of by an average household. this would ensure the company would not lose money, and in fact may even make money.
