Well, in many regions, trash collection is a municipal monopoly, so your customers are going to be city councils, not people.

Also, in many places, "curbside sorting" of the type you describe already takes place. Here in Norway, I get three trash bins from the city-- one for regular trash, one for paper, and one for food trash. About 25 years ago I lived in Montpelier, Vermont and there we had two streams-- one for recyclables like paper, plastic, and metal cans, and one for everything else. Both of these are based on weekly pickups-- daily pickups would be prohibitively expensive, it seems to me, and would also enlarge the environmental footprint (in terms of fuel required.)
