I lived in Bali for 2 years and this was all there was. Either you burned your trash or you were a westerner that had money to pay for someone to collect it. They gave you bins and taught you how to separate it. You get very conscious of what you can and can't throw away when it doesn't just magically disappear. But I think it'll be hard to convert people who are not used to thinking of their trash as a cost they are burdened with. Most Americans are used to thinking of it as right. In italy we have to pay a tax trash and it's usually a contract given to a private company In the town I live they provide special bags and you put out certain materials on fixed days. In other words, it's done in many places, but whether it's profitable is another story. I think you have to find a way to really convince people how right it is and find someone to supply the "trash" to who ideally pays you something for the raw material.
