This is an exciting idea!!! I like the idea of creating a mobile app, and the rewards system (exchanging the compost for food credits) is genius. I agree with Angela Holtzen: How can we spread this idea nationally?
Do you feel that it is more beneficial to work on this project in a place that is densely populated and less environmentally savvy --where the idea will bring great benefit but will have a difficulty getting similar support -- than it is to introduce the idea in an area that is more environmentally savvy, such as Denver CO, where there may be considerably more support & engagement of the project?
I'm totally biased in this perspective, given that I live in Denver. But from an outside perspective... inquiring minds want to know :)
