Well, a lot of major cities in Asia have already solved this by either changing how they handle the public garbage pickup requirements (e.g., Korea has special bags for regular trash and organic trash you need to purchase, else the garbage collectors won't take it), and also doing more frequent/regular pickups and having you sort your trash in order for it to be accepted. In my short time in Korea, just knowing you have a direct cost on the trash by means of the bags changes how you shop and produce garbage. I don't think this is something you need an app for. Maybe the city can use it to manage notifications, but they could do this just as easily through free SMS or through a unified public announcement system/site. It doesn't seem like something looking for disruption, except for those who want to needlessly introduce a middle-man into garbage collection.
